What can you use instead of a soldering iron - Metals and their processing

What can you use instead of a soldering iron?

Any soldering can be successful only if all requirements for the procedure are met. One of the main conditions is to use a multicomponent flux or regular rosin.

There are a sufficient number of ready-made products on sale. Rosin is considered the most affordable and popular. It happens that the material is not at hand, but something needs to be soldered urgently.

We have to figure out what can replace rosin without compromising the result of the work. Fortunately, a large number of special fluxes are produced, and in addition to them, you can use improvised means.

Material requirements

Any flux is designed to remove oxide deposits on metal parts, prevent oxidation during soldering, and improve the distribution of solder mass in the work area.

Rosin copes with the task successfully. The connections are high quality and durable.

When thinking about how to replace rosin at home, you should remember the need to perform all functions with solder.

The replacement must meet a number of the following requirements:

have a low melting point and low density;
melts well with a soldering iron;
do not spread outside the working area;
effectively dissolve oxides;
evenly distributed over the surface;
do not react with metal parts and solder;
can be easily removed upon completion of work.

Flux decomposition products, together with dissolved oxides, should be easily pushed out of the weld formation zone by the solder melt.

Natural light yellow rosin, similar to a glassy mass, is ideal. Experienced craftsmen suggest what can replace it.

Aspirin and battery electrolyte

Many experts consider the most affordable option to be the use of pharmacy aspirin.

Please note that it will not be possible to replace rosin with effervescent tablets. They contain fillers (sodium compounds) that are not needed for soldering. Therefore, the most common simple aspirin is used.

The tablets should be crushed to a powder and dissolved in water or regular wine-vodka alcohol. You can use cologne as a solvent.

Acetylsalicylic acid dissolves well. Its properties are often sufficient to clean the surface and remove dirt. It can replace rosin without difficulty.

The inconvenience is the need to work under a ventilation hood or in a ventilated place. Solders without rosin with aspirin release sharp-smelling, harmful gases when heated. It is not necessary and impossible to breathe them.

If aspirin is not available, it is recommended to replace rosin with electrolyte from a used salt battery. It is important that it is not alkaline.

Fat, resin, amber

Animal fat melts well and is distributed on the surface. Any fat, both food and industrial, will do.

Odors during work are unpleasant, but they can be tolerated for some time without ventilation.

Many craftsmen, especially those living surrounded by forests, use ordinary tree resin. It melts easily and spreads well over the surface of the working area.

There are positive reviews about the use of spruce and pine resin. It is collected in ordinary tin cans, crushed as much as possible, and then slowly melted in a water bath.

The melt must be constantly stirred, removing needles and wood particles from it. This material is as close in composition as possible to rosin. Therefore, you can replace it in this way without any problems.

To solder iron, it is recommended to dissolve wood resin in food vinegar. Please note that you cannot use essence or concentrated acetic acid.

Amber is very suitable for use as a flux. The advice is acceptable for residents of regions where amber is mined. For everyone else, it is difficult to replace rosin with amber. The price is too high.

Non-standard methods

If there is no rosin nearby for soldering, you can use material for rubbing bows. It's better cleaned. All properties are saved. The cost of replacement will be significant.

Savvy craftsmen who have solders with flux suggest soaking it in alcohol and waiting until the rosin has completely dissolved. It takes a little time.

They say that such an alcoholic extract can successfully replace rosin. The alcohol component will gradually evaporate. The solid component meets the requirements for fluxes.

When working with old equipment, you can replace rosin with residues in places of old soldering. You need to touch the wire and soldering iron there and make a connection. This method is acceptable for extreme situations with not very high requirements for seams.

Acids with stearin

It happens that there is nothing suitable for replacement nearby. Then any acid except concentrated sulfuric and nitric acid is suitable for removing oxides.

To prevent oxidation of the metal, you can thoroughly clean it and the solder, then coat them with stearin. Stearin (paraffin) can be taken from candles.

Before applying a protective layer to the metal, stearin must be melted without overheating. The protective layer will prevent contact with oxygen. Soldering should be carried out under the stearin layer.

Some craftsmen, in order to replace rosin, spread the well-known BF-6 glue onto the cleaned metal surface. In this case, you need to solder while pressing the soldering iron firmly.

The above methods are a “first aid” for a solderer. In unexpected situations, a way out can always be found using simple and accessible means. But still, for the quality of soldering, it is better to use special tools.

The wire that was soldered has come off the garland, is it possible to repair it without a soldering iron, how else can this wire be attached?

Usually, a broken wire can be returned to working condition if you simply connect its two ends together at the break point - in theory, for electric current, it is not even necessary for the wire to be a single whole and it will flow, even if the wires are just tightly adjacent to each other . Therefore, to restore the working state of our device, it is enough to simply, for example, twist the wires together (only when the electrical appliance is turned off, of course. For extra safety, you can even wear rubber gloves), and then wrap the fastening area with electrical tape.

If you still need to solder the wires, then in the absence of a soldering iron you can use solder paste.

Without a soldering iron, you can firmly attach the wiring to the wiring in order to further use it for its intended purpose.

It’s not news to anyone that wires can be twisted by hand, having first disconnected them from the electrical network. Twisted wires must be well insulated with insulating tape.

Improvised means for replacing rosin

Any soldering can be successful only if all requirements for the procedure are met. One of the main conditions is to use a multicomponent flux or regular rosin.

What can be used instead of solder when soldering?

MiscellaneousWhat can be used instead of rosin when soldering

What can you use instead of rosin for a soldering iron?

Aspirin, citric acid, ammonia, zinc chloride, phosphoric acid. All of these need to be washed with water and an alcohol-gasoline mixture. When using aspirin or citric acid, you need a gas mask or a fume hood. Long ago, when it was difficult to get rosin, I used resin removed from the trunks of pine and spruce trees. It soldered normally, but there was a smell!!!
I solder with acetyl acid. Great
Nothing will probably come of it using improvised means. You go to the market and ask for flux or acid for soldering. If they are not available, then you buy rosin)))) Although it is more convenient to solder with flux
Soldering flux LTI-120, 15 r bottle - works well but requires washing the soldering area with water. Also, Tags flux and Zil-2 flux. They even solder stainless steel and nichrome.
aspirin really stinks.
mixed citric acid with paraffin!!! It helped!!!
solder fat
A good flux, neutral (not acidic), is obtained from a solution of glycerin in water. Aspirin is good because it solders anything, even enamel-insulated wires. But this is nuclear acid, so the board must be washed THOROUGHLY afterwards.
Citric acid helped, thank you!!!!
Aspirin, amber, fat, almost any resin. The principle is to create an anti-oxidation film, since when it is not heated, oxidation is faster and the oxide film does not stick.. And fluxes also remove this film with acid..
I used lemon juice squeezed straight from the lemon into the glass. It is advisable to rinse the soldering area with water afterwards.
Old Soviet aspirin is best. if not, you can try paraffin or stearin - a candle. But this is a last resort, it fluxes rather badly.
citric acid (dry, not solution)
Amber. Seriously, acid, soldering flux (I don’t remember the composition).
Acitylsalicylic acid tablets, I solder them myself, great
Try fusing a piece of candle with aspirin.
hydrochloric acid pickling with zinc.

For most Russians, a soldering iron is not an essential tool. In this regard, many consider its purchase inappropriate, preferring to spend the money on something more necessary.

Meanwhile, in any household, sometimes something breaks, and repairing it without a soldering iron sometimes seems simply impossible.

What to do? Is it really necessary to use such carefully stored savings and buy a tool that, most likely, will then gather dust on the shelf for many years? There's no need to rush. It turns out that there are a lot of things around that can be used instead of a soldering iron.

A soldering iron is not an essential tool at home, so you can use its substitutes.

Method number 1: current strength

You need to prepare:

battery;
solder with rosin;
two wires;
a simple pencil;
alligator clip.

This method allows you to do not only without a soldering iron, but also without access to the mains, if, of course, the battery has a charge. The sequence of actions is as follows:

Composition of a welding pencil.

Connect the two wires that need to be soldered and place two or three turns of solder with rosin inside in place of the soldering.
Connect one of the wires to either pole of the battery.
Having removed a fragment of the wooden shell 5-10 mm long from one side of a simple pencil, connect the graphite rod via a wire to the second pole of the battery.
To solder the wires, touch the lead of a pencil to the solder for a moment. Under the influence of an electric arc discharge, it will immediately melt, and soldering without a soldering iron will be successfully carried out.

The described method combines soldering and welding. It can be used to connect thin wires whose diameter does not exceed 1 mm. By increasing the arc discharge time, it is possible to weld copper wires without solder.

Note that this method requires some skill, so it is better to first practice on unnecessary parts or waste.

Method No. 2: using solder containing tin

This method involves using a tin-lead alloy with a 62% tin content as solder (this is a tertiary). It can be used to solder small parts or wires made of copper, iron and zinc. You need to do the following:

Instead of a soldering iron, you can solder with a special alloy of tin and lead.

Treat the surfaces of the parts that need to be joined with sandpaper or a file.
Using a brush, apply a zinc chloride solution to the areas to be joined. If you don’t have one, you can prepare it yourself by dissolving zinc shavings in hydrochloric acid. Upon contact with skin, hydrochloric acid causes severe burns, so perform all operations with it observing safety precautions.
Place a small amount of “tertiary” on one of the parts.
Heat the part with the alloy placed on it with a candle or alcohol burner until it begins to melt.
Attach the second piece to the semi-liquid third piece.
Warm up the soldering area well, then let it cool. To speed up the cooling process, you can add a few drops of water.

If you need to solder two wires, attach one end of a tertiary in the form of a strip or thin rod to the junction.

https://www.youtube.com/watch?v=uPcwfKYVp1s

In the absence of components from which zinc chloride can be prepared, dry ammonia or borax can be used as its substitutes. It is better to treat wires in electrical connections with an alcoholic rosin solution before soldering.

The tertiary is used for tinning parts made of copper or iron. To do this, the part is lubricated with a solution of zinc chloride, then heated well and the alloy is spread over its surface.

Method #3: Using a Small Paper Clip

You need to prepare:

Necessary tools for a soldering iron made from a paper clip: 1 - metal clip, 2 - pliers, 3 - autogenous lighter, 4 - slotted (flat) screwdriver.

metal paper clip;
pliers;
autogenous lighter;
slotted (flat) screwdriver.

It turns out that a regular paperclip can also be used instead of a soldering iron. To do this you need:

Bend one curl, partially straightening the paper clip, and grab it in the middle with pliers so that both parts protrude from different sides.
Now the part where there is more metal needs to be heated with a lighter.
After some time, the heat will spread to the second part, which will play the role of a soldering iron tip. You won't have to wait long because the paper clip heats up quite quickly.
To check the readiness of this makeshift tool, hold the free end of a paper clip to the tin. If the required temperature is reached, it will begin to melt.

In this method, tin is used as solder. A small amount of it should be placed on the parts to be joined, after which you can begin soldering. When using a paperclip instead of a soldering iron, one end must be constantly held in the flame of a lighter, otherwise the tool will instantly cool down. It is best to entrust this task to an assistant.

A soldering iron clip is most suitable for soldering microcircuits and other very small parts.

Method number 4: soldering with wrapping

If you need to solder two wires up to 2mm in diameter, use this ingenious solution. You need to do the following:

A battery-powered soldering iron can be used to connect thin wires.

Remove the insulation from the wires (about 30 mm) and strip them.
Laying bare sections of wires on top of each other, twist them.
Attach foil from below to the junction and lift its edges so that the wires appear as if in a groove. The thickness of the foil should be about 0.08 mm, it can be removed from the old capacitor.
Apply solder on top of the wires. It is a mixture of rosin (1 part) and finely planed POS-30 solder (4 parts).
Wrap the soldering area with solder in foil.
Now the foil with all its contents needs to be heated. To do this, it is not necessary to use a torch; you can get by with three matches, the flame of which must be held under the soldering area for half a minute.
After the workpiece has cooled, remove the foil. If everything is done correctly, the wires will be securely soldered.

Flux for soldering steel with tin

Method number 5: patching holes

If a small hole (up to 5-7 mm) has formed in a metal dish or any part, it can be repaired by soldering, but without using a soldering iron.

The metal around the repair site should be cleaned with sandpaper; you can also use brick powder for this purpose. If the product is covered with enamel, it must be knocked down so that clean metal about 5 mm wide is formed around the hole.

The enamel can be removed using a sharp metal object, such as a nail, which should be tapped several times not very hard.

The stripped metal must be treated with etched hydrochloric acid, and then a small amount of rosin must be poured onto it.

After this, a piece of tin or a tertiary, which was described above, is placed on the inside of the hole, and heated on an alcohol burner. In the absence of one, you can use a primus stove, an electric stove or even a kerosene lamp. The tin will melt and the hole will be sealed.

Method No. 6: pencil welding

Soldering with foil.

You can solder products using a special pencil; today these are sold in many stores. The pencil must be ignited from any source of fire. When burned, the material from which the pencil is made begins to melt and drip.

When the required amount of it is at the connection site, the parts must be pressed against each other with force and held in this way until the solder cools and sets. This method can be used to fasten not only metal elements (the parts do not even need to be cleaned of rust), but also ceramics, heat-resistant plastic or glass. The connection remains stable at temperatures not exceeding 180° C. The length of the pencil is enough for several dozen small connections.

Method number 7: cold soldering

In the absence of a soldering iron, electrical contact between two conductors can be restored using a special composition. Such materials are produced both by domestic manufacturers (Kontaktol K-13) and foreign (Quick Grip, etc.). Cold soldering is based on electrically conductive glue, so it can completely replace traditional soldering. The main thing is that the operation is carried out at above-zero temperatures:

Before using such a composition, wires or other connected elements must be cleaned of oxides and treated with a degreaser.
Next, apply one layer of the composition, and after waiting for 15-20 minutes, apply a second one.
Now the parts can be connected. Cold solder dries within 1.5-3 hours at an ambient temperature of 18° C, but it is recommended to turn on the repaired device only after 24 hours.

From one such soldering iron of a standard volume (0.8-1.4 ml) you can squeeze out a strip 100-150 mm long, so the cold soldering resource is quite decent.

If you live far from specialized stores, you can prepare your own cold soldering agent. To do this, just mix a certain amount of small metal filings with nitro glue or varnish. The finished mixture must be applied to the joint using a narrow spatula or a pointed match.

If the parts to be connected are on a substrate, it is better to attach a magnet to its reverse side. When connecting thin elements (wires or tracks), it is better to place a small sheet of paper or plastic film with a slot in the soldering area, and only then apply the compound.

The cold solder will only get to the connection point (through the slot), and the surrounding elements will remain clean.

Aspirin tablet. Pine resin.

You are a strange person. You don't explain the question. It's one thing to seal a pan, and another to use twisted pair cables in computer equipment. You should explain it right away.

Aspirin is also an acid. Then you will need to wash it with a soda solution. Do you have a Christmas tree (not an artificial one) at home? Chop up the resins.

Acetylsalicylic acid (tablet)

How funny it is, but machine oil, or aspirin, or resin/rosin, or zinc chloride, or glycyrin, or a hellish mixture of all this. After soldering, rinse!!! But it’s better - go and buy a normal flux!!! ! Yes, and in your case, welding is better than soldering!

Composition of a welding pencil.

Connect the two wires that need to be soldered and place two or three turns of solder with rosin inside in place of the soldering.

Note that this method requires some skill, so it is better to first practice on unnecessary parts or waste.

Dismantling methods

In some cases, for dismantling it is possible to use a soldering hair dryer, which, by heating a large area, melts the solder on all contacts.

But using a hairdryer can be inconvenient when the installation is tight. It is possible to heat the solder on the legs of adjacent components.

The ideal would be dismantling, in which the contact pads remain clean and tinned. Sometimes mechanical and chemical methods are used.

To carefully remove solder from the board, it is better to use a soldering iron. There are several options available:

remove solder directly onto the soldering iron tip;
use a desoldering pump to remove excess solder;
remove using braid.

Solder can be removed mechanically using a file or needle file. This method is fast, but rough. When using the chemical method, the solder is dissolved by aggressive materials, for example, some acid solutions.

Sometimes compressed air is used to clean the board, which blows off excess material. But this method is rarely used, as it is crude and even quite traumatic.

Removal with a sting and using a desoldering pump

Instead of a soldering iron, you can solder with a special alloy of tin and lead.

Treat the surfaces of the parts that need to be joined with sandpaper or a file.
Using a brush, apply a zinc chloride solution to the areas to be joined. If you don’t have one, you can prepare it yourself by dissolving zinc shavings in hydrochloric acid. Upon contact with skin, hydrochloric acid causes severe burns, so perform all operations with it observing safety precautions.
Place a small amount of “tertiary” on one of the parts.

Warm up the soldering area well, then let it cool. To speed up the cooling process, you can add a few drops of water.

If you need to solder two wires, attach one end of a tertiary in the form of a strip or thin rod to the junction.

How can you replace a soldering iron at home - Metals, equipment, instructions

> Electrician's tips > How to solder a wire without a soldering iron

Sometimes the question may arise as to how you can solder a wire without using a soldering iron, because soldering is the most common way to connect small parts at home.

There are situations when an urgent wire connection is required, but the soldering iron, used as a simple and convenient tool, is in a broken state. Almost everyone knows how to combine metals armed with it.

But how soldering is carried out if there is no electricity at home is another question that we will consider below.

Soldering without a soldering iron

Using a homemade sting

Not everyone at home has such an ordinary tool as a soldering iron, but there are plenty of different breakable devices. Most often these are phone chargers or headphones from which the plug has broken off.

Of course, if necessary and possible, you can buy new accessories, or you can breathe new life into old ones. You can replace the soldering iron using ordinary available materials.

In a word, a simple soldering iron tip is made, for heating which any fire source is suitable.

Homemade soldering tip

The available materials are as follows: a single-core piece of copper wire (diameter - 0.5 cm), as well as a small piece of fabric resistant to high temperatures. You can use the wire as a tip; one side of it needs to be carefully sharpened at an angle of about 45 degrees. This will serve as a soldering tool in the future.

As for the other end of the cable used, it is reliably thermally insulated so that it can be safely held. Fiberglass or, at worst, ordinary jeans will be suitable as an insulator. Simply cut a long piece of fabric and wrap it around the wire. To fix the fabric, use thread or glue.

Now let's move on to the most important thing: how to carry out soldering with such a homemade tip. First of all, you will need a source of fire. For example, a gas stove will serve them. You should take the sting and heat it thoroughly. Next, when it heats up, it touches rosin and solder, as a result of which the end of the tip becomes tinned. A tool, even a handy one, in this condition, is suitable for soldering.

For example, what to do if your phone charger is broken. First of all, you need to carefully strip the ends of the wire using a knife. Next, a heated tip is used, with which the ends of the copper wire are tinned. Soldering is used to connect the break point.

Important! When soldering, make sure that the wire being processed is thoroughly stripped. To remove oxides from the surface, a regular knife is most often used, resulting in high-quality tinning.

When using a homemade tip that replaces a soldering iron, you just need to lightly touch the damaged wire, as a result of which it will tin normally and quickly.

Soldering with foil

Principle of operation, main malfunctions and methods of repairing a soldering iron

Using this method, soldering is completed in 5 minutes. In this case, foil is used as solder, which is rolled into a thin strip. This form is considered very convenient, since it will not spread over the area and leak with a larger dosage, which is physically impossible.

Soldering foil

The type, location and size of the contacts can be any; with this method there are no specific restrictions. Foil soldering is useful in a variety of situations, from soldering a wire to a board to connecting the contacts of two twisted wires.

In order to prepare the contacts, you will need to remove the insulation from them and clean them of any residue. Next, the ends of the wires are connected by twisting, the required amount of foil is cut off, the adhesive tape is removed, and the wire is wrapped. Next, uniform heating is carried out, for which a candle or a regular lighter is suitable.

How to solder a garland using improvised means

In the case of a garland, first of all, you will need to find the place where the wire was disconnected. The reason for this may be:

Often the contacts break in the control unit, where thin wiring does not provide sufficient adhesion area;
Also, the gust can be along the entire length of the garland;
If the lamps are connected in parallel, then if one burns out, the entire circuit will open.

Note! Before starting work, you must disconnect the garland from the network.

As a rule, contacts that have moved away can be easily found with the naked eye. In other cases, a special tester may be needed: each half is measured, after which the search range is gradually narrowed until a non-working element is found.

Having found the location of the rupture, you can begin the soldering procedure. It should be noted that in this situation the solderless method is most relevant, which is explained by the small diameter of the wire. Paste and heat shrink tubing will be effective here. The diagram looks like this:

The wire is cut at the break point;
It is being cleaned;
The tube is put on in advance and moved to the side (until soldering is completed);
The twist is done and the paste is applied (there is no need to touch the edges of the insulation);
The solder is thoroughly heated using a candle or lighter;
The cooled area is covered with an insulating tube, which must also be heated.

You can solder broken headphones using the same method.

The soldering iron is known as a convenient and simple tool, but there are situations when it fails. There is no need to worry, since soldering can be done using improvised means. It is enough just to know some nuances.

How to do without a soldering iron at home

How can you replace a soldering iron at home if you need to solder something? What should a home soldering iron do? Essentially, it’s just a matter of being able to melt solder and apply it to the contacts. This operation will help you repair a broken wire in a household appliance, change a board part, or fix a broken part. Any soldering iron will cope with the tasks, but there are many tools that can perform simple repairs just as well.

1 Portable or battery-powered analogues
2 Soldering iron from a lighter

Portable or battery-powered analogues

This type of soldering iron, such as battery-powered ones, is very difficult to buy. But the need for it may appear quite often - if the product is repaired outside the workshop or in the absence of power supply at all. For example, when working at heights, when a car breaks down on the road, and so on. The easiest way to solder a battery will require solder with rosin (inside) and a pencil rod.

Take the battery and connect one electrode to the part, and wind the second on the rod. Now lower the solder onto the soldering area and touch it briefly with the lead. The resulting electric arc should melt the solder and perform a kind of seam welding. The resulting seam is not even soldered, but welded, which makes it quite durable. The method is safe, but it is better to practice first.

Soldering iron from a lighter

This is the most popular method among “homemade bloggers” because it is quite simple and at the same time effective. You will need a paper clip and a lighter. One end of the paperclip is unclenched, and we hold the other with pliers or with our hand in a construction mitten (not safe).

We heat the free end with fire and apply it to the solder already lying at the soldering site. The only drawback is that it is difficult to find a lighter that is reliable enough so that you don’t have to worry about its integrity during prolonged heating.

THIS IS INTERESTING: How to weld a fillet weld with a semi-automatic machine

If the tip of the paper clip is not very strong, you can take a nail, but it is better to heat it on a more powerful heat source, for example, a gas burner.

There are also special cold alloys, consisting of two components, when combined, a chemical reaction occurs with the release of heat. As a result of the reaction, the tin contained in the composition melts and forms a correct solder seam. You use the tips from this article at your own peril and risk, so it’s better not to skimp and buy an inexpensive soldering iron. This tool will be useful in the kit of any home craftsman; it will allow you to quickly repair a household appliance or simple electronics.

How can you replace a soldering iron at home?

A soldering iron is a very useful tool in the household. With its help, you can perform various minor electronic repairs, connect various parts, etc.

However, in practice, the need to use it at home is relatively rare. Buying a tool just to use it occasionally is not very profitable.

There is a great solution! If desired, you can replace the soldering iron with many other tools and devices that will allow you to do the job no less efficiently.

Battery-based soldering device

When figuring out how to replace a regular soldering iron, it is recommended to first pay attention to this device. With its help, it will be possible to perform soldering even in the most inaccessible places without access to electricity, at heights, etc.

To assemble this homemade soldering iron you will need the following:

Battery.
Solder with rosin.
A couple of wires.
Pencil with graphite lead.
Alligator clip.

In fact, the process performed using such a homemade soldering iron is not soldering, but welding. Everything is done as follows. You take 2 wires and wrap a couple of turns of solder on top with rosin inside.

Next, you need to connect any battery electrode to the products being soldered. Connect the second electrode to the graphite rod of the pencil. It must be cleaned first. Next, you need to touch the solder with the rod for a split second.

An arc will appear, and under the influence of high temperature the solder will instantly melt, which will ensure very reliable soldering.

This method is suitable for connecting wires with a diameter of no more than 1 mm. If you hold the graphite rod on the tip of the wires a little longer, you can get a weld on the copper wires. Before using such a soldering iron, it is recommended to practice a little on unnecessary products.

Soldering using a special alloy

If you need to solder various small parts made of zinc, iron and copper, you can also successfully do without a soldering iron. In this case, a special alloy called “tertiary” will help you. It contains about 62% tin, the remainder being lead. The tertiary allows you to perform reliable soldering without a soldering iron.

Before starting work, you need to properly prepare the surface of the products to be soldered. To do this, you should first clean the part using sandpaper or a file, and then moisten the entire surface with a solution of zinc chloride.

It is more convenient to do this with a brush. In the absence of zinc chloride, it can be prepared from zinc metal. It is enough just to dissolve it in hydrochloric acid.

Be careful when performing this step of the job, as the acid is a potentially dangerous compound.

After completing the preparatory stage, you need to take a piece of the alloy and place it on the surface of one of the parts to be joined. Next, you need to take a heating pad or, in the case of soldering small parts, an alcohol lamp or candle and thoroughly warm the junction with the tertiary.

If it is necessary to solder the wire, you need to touch the strip of the tertiary to the heated surface, previously moistened in a solution of zinc chloride. A fairly large amount of alloy should separate. Wait until it spreads over the product, then attach another part. Warm up the joint thoroughly and leave to cool. In the absence of zinc or hydrochloric acid, the surface can be treated with brown or dry ammonia.

It is best to solder electrical wires using rosin dissolved in alcohol. Pour water over the joint to cool it, then clean it with an old file. If you need to tin a copper or iron part, moisten it with a solution of zinc chloride, then spread the alloy over the surface. The part should be evenly heated on the flame of an alcohol lamp or burner.

“Soldering iron” made from a lighter and a paper clip

Instead of a traditional soldering iron, you can use this device. It is assembled from the following components:

Flat screwdriver.
Pliers.
Autogenous lighter.
An ordinary paper clip.

One ring of the paper clip needs to be bent. The other end should be straight. Secure the paperclip in the pliers and heat thoroughly using the flame of a lighter. If possible, it is recommended to use a reliable lighter that can provide a steady flame for an extended period of time.

Your task is to heat the metal of the paper clip to the desired temperature. In this case, the required temperature refers to the melting temperature of tin. It is relatively small, so you won't spend a lot of time.

After the paperclip is red hot, apply the hot part to a piece of tin and observe what happens.

Now you can proceed directly to the soldering process. This method is best suited for working with various microcircuits. Take one of the parts to be soldered, press it tightly against the other and place a small piece of tin next to it. Heat a paperclip and touch it to the tin to melt it. When soldering microcircuits, you need to be careful not to damage entire parts of the product.

To make work as comfortable and productive as possible, the paper clip must be constantly maintained in a hot state. It is more convenient if you have an assistant. He can heat the paperclip while you do the soldering.

The method is quite simple and convenient when performing various small jobs that require control at each stage of execution. It may take some time to master such an improvised soldering iron. It’s better to practice on unnecessary products before starting finishing work.

Proven method for soldering wires

If you need to solder wires or cable cores with a diameter of up to 2 mm and you don’t have a soldering iron, you can use the following simple and proven method. First you need to strip about 3cm of insulation from the wire. Carefully trim and twist the ends. Take a sheet of aluminum foil, make a groove out of it and place the previously prepared twist in it. Use 0.08mm thick foil. For example, foil from an old capacitor will do.

Prepare your solder. It should consist of 1 part rosin and 4 parts fine shavings of POS-30 solder. Pour the prepared mixture over the twist and squeeze the foil. It will crimp the twist with solder well and will hold firmly to it. Heat the soldering area.

You don't need any special tools for this. It is enough to take 3 matches, light them together and hold them under the twist for 20-30 seconds. After this, wait 15-20 seconds until the twist cools down. Remove the foil. The wires and cores will be soldered.

Select the width of the foil according to the exposed area of the twist.

Instructions for sealing small holes

This method is suitable for sealing small holes with a diameter of up to 5-7 mm, for example, in leaky dishes. First you need to thoroughly clean the area around the hole. Do this using sandpaper, a file or grated brick. If you are going to solder enameled products, you must first remove the enamel by about 5 mm around the hole. To do this, place the corner of a metal object against the edge of the hole and knock off the enamel by lightly tapping it with a hammer.

Clean the exposed metal thoroughly. Take finely ground rosin and pour it over the soldering area. If you have etched hydrochloric acid, coat the product with it. On the inside of the product, place a piece of tin or, even better, a tertiary on the hole. Next you need to heat the product.

This can be done over a kerosene or alcohol lamp, a primus stove, or even an electric stove will do. In the case of enamel cookware, an alcohol lamp is most preferable. It will ensure heating of a small part of the product and will not damage the rest of the enamel. Wait for the tin to melt and remove the pan from the heat.

Molten tin will provide a strong and reliable soldering.

A welding pencil is an excellent alternative to a soldering iron.

Currently, specialized stores sell special pencils that allow you to do without a soldering iron or other equipment. To work with them you only need one lighter. The work is done quickly and easily. This pencil successfully replaces a soldering iron when performing many different tasks of varying levels of complexity.

This pencil soldering iron can be stored for an unlimited time, so it is recommended to buy it “just in case” and have it in your DIY kit. A soldering iron and access to electricity are not required. You can solder products from the following materials:

Gland.
Cast iron.
Durali.
Aluminum.
Become.
Of stainless steel.
Brass.
Slate.
Copper.
Bronze.
Heat-resistant plastic.
Ceramics, etc.

Thanks to the special composition and structure of the welding stick, soldering will be reliable even on surfaces damaged by corrosion. Can be soldered in vertical and horizontal planes.

Instructions for using such a “soldering iron” are given on its packaging. Be sure to clarify the main points before use. In general, the technology is as follows.

You take a pencil, light it with a lighter or other convenient method, and apply the molten mass to the damaged area. The pencil stops burning, but the burning on the surface continues. In general, it takes about 20 seconds for the surface to warm up.

After 15-20 seconds you need to solder the molten mass into the surface. You can use the same pencil for this.

This “soldering iron” creates a soldering joint that can withstand an average temperature of up to 180 degrees. One pencil allows you to perform up to 25-30 rations.

Thus, even in the absence of a soldering iron, you can complete the required work. There are several time-tested methods, and now you understand the main ones. Choose the most suitable option and get started. Good luck!

What can be used instead of flux for soldering?

When high-quality and fast soldering is required, it is advisable to use rosin.

Anyone who loved to solder at home as a child or attended amateur radio clubs definitely had these amber pieces in their arsenal, but rarely thought about why rosin was needed.

Let's look at its useful properties when soldering and what can replace it.

Technology and terminology

The starting material for the production of rosin is ordinary pine resin, which, in addition to rosin, contains volatile turpentine compounds.

The manufacturing process involves purifying the rosin by evaporating these compounds.

For those who have never used a soldering iron, but are planning to learn how to solder, it will be useful to know some technical terms.

Soldering is the process of connecting two radio components together through heating.

The soldering tool is a soldering iron, usually powered by 220 mains power with a rated power of 40W.

The soldering process is carried out using a soldering iron tip due to the fact that solder heated to a high temperature grabs two parts together, filling the space between them.

GOST defines solder as a metal or an alloy of several metals. According to GOST, 26 categories of solder are defined depending on the element used.

The most popular alloy is lead and tin in various proportions. Price also plays an important role in popularity.

Solders always have a lower melting point than the parts to be joined.

According to GOST, according to their temperature properties, solders are divided into soft ones, which melt at temperatures up to 450 degrees Celsius (with subcategories of particularly low-melting ones - up to 145 ° C and hard ones with a melting point of 450 degrees Celsius and above (categories of medium-melting - up to 1100 ° C, high-melting - from 1100 to 1850ºС and refractory – over 1850).

GOST divides solders into fluxing and self-fluxing; they have different melting points.

Most often, solders look like a silver-colored metal tube or like a hollow cylinder filled with rosin, which acts as a flux.

:

Flux is a composition (liquid or solid) that promotes better contact of parts being soldered and prevents metal oxidation on working surfaces.

Requirements for fluxes are also determined by GOST; they have different prices.

For a beginner, solder with rosin will be more convenient, while experienced craftsmen like to solder with ordinary solder, choosing a flux depending on the soldering conditions and the material of the parts.

If simple soldering of copper parts will be carried out, then you can use rosin; its low price makes it a convenient consumable.

Technical requirements for the use of rosin for soldering, its composition, melting temperature and characteristics are determined by GOST 19113-84.

The main material for rosin is pine resin - the raw material for many types of industry and an auxiliary element for soldering.

It is a composition in the form of a mixture of abietic resin acid with several other isomers of resin acids.

Lacking a crystalline structure, it is an amorphous, glass-like, brittle substance with a wide range of colors from pale yellow to dark brown.

In composition, it is a glassy, transparent mass with inclusions of air bubbles, with minor inclusions of mechanical impurities, a mass fraction of water not exceeding 0.2%.

It is absolutely insoluble in water, but easily dissolves under the influence of alcohol and acetone. Rosin softening occurs at a temperature not lower than 66-69ºС, depending on the variety.

Mastering soldering with rosin

The composition of rosin for improving soldering is manufactured and sold both in pure solid form and in the form of liquid or viscous fluxes, its price varies.

The most common is alcohol-rosin flux (brand “SKF”), which according to GOST consists of a 40% rosin solution and pure ethyl alcohol.

It is this flux with rosin that is a dielectric, unlike ammonium chloride flux. In addition to the technical properties of this flux, the low price is important.

:

Instead of liquid flux, you can use solid rosin; it is also available in stores for radio amateurs.

The price of one kilogram of solid rosin ranges from 400 to 500 rubles. When rosin is purchased, a soldering iron and regular solder (tin) are available, we get to work.

If you have not had to solder before, then first read the video instructions. The technology of soldering using rosin is presented in the video.

To solder firmly and correctly, follow the following sequence.

Soldering iron preparation - tinning. It involves stripping the soldering iron tip with files and then coating it with a thin layer of solder.

Warm up the tip and put a small amount of rosin on it, then immediately connect it to the solder. As you can see in the video, the solder does not stick to the tip, and we need to ensure that it is evenly covered with solder.

Therefore, we apply the sting to a natural board (pine is best, but you can use any) for a short time. We repeat the sequence.

After several cycles we will achieve the desired result. Preparation of surfaces to be soldered.

Let's tin the wire, to do this we will clear it of the insulating layer, but only as much space as we need for soldering.

If a larger surface of the wire is exposed than is required for soldering, then this, of course, is convenient for a beginner; this is precisely the reason why short circuits and fires occur in the circuit.

Typically, pure copper wire can be tinned after one rosin-solder cycle.

Let's dip the wire in rosin, apply a hot tip to the top of the bare surface and lift the wire.

The rosin mass will smoke and flow around the wire, after which all we have to do is cover the soldering area with tin. To do this, pick up tin from the solder with a hot tip and transfer it to the wire.

If the wire turns from copper-yellow to silver, then it is considered correctly tinned. When you need to connect two wires by soldering, both need to be tinned in the same way.

:

Let's look at how to prepare a copper part for soldering to which you need to solder a wire. Dip the heated tip into the rosin and immediately into the solder.

Now we have a rosin-tin mixture at the tip of the sting. It needs to be thoroughly rubbed over the surface of the part at the soldering site.

Tinning is done correctly if the place where soldering will be done turns silver.

Instead of solid rosin, you can use any flux.

In order to properly solder the tinned parts, we connect them together, pick up tin with a heated soldering iron (it can be replaced with any other clean solder), and cover the joint of the parts with a hot compound.

If it was not possible to enrich the joint of the parts immediately, then you can touch the soldering iron with tin again.

If you notice that the enveloping is not going well, then add as much rosin as required, but in small portions.

Let's look at how to properly unsolder parts. We heat up the tip and apply it to the soldering area. This will melt the solder and the parts will easily separate from each other.

Now dip the brush into the solvent and remove the remaining flux and rosin from the surface of the parts.

Secrets of soldering with rosin

There is no difficulty in soldering work, but, as in any type of work, it is necessary to master the basics and carry out a series of training solderings.

If you have never worked with a soldering iron before, try soldering copper wires using ordinary solder and rosin.

:

Free access to parts from all sides, the ability to combine them quite tightly are good conditions for developing soldering skills, and using rosin separately will teach you how to dose the required amount.

Please note the following points:

The cleanliness of contacts for tinning before soldering must be ensured properly, this is the price of strong soldering. After cleaning the surfaces to be joined with a knife, go over them with sandpaper. The goal is to make the metal surfaces of parts brighter, and therefore free of copper oxidizing agents;
Prepare as much surface as you need for soldering with rosin. If the first time you managed to tin a larger surface than required, redo it by taking new wires;
If there is not enough solder or flux, leave the soldering to harden. When you try to rub hot compound over a surface, you break the solder joint, which will cause cracks. It is better to wait until it cools completely and solder the remaining surfaces using a new composition.

We looked at how to work with a soldering iron correctly, for what you can and should use fluxes and rosin, highlighted several points that will help you learn to solder better, and showed video instructions for working with a soldering iron.

Now you can easily master soldering with rosin at home.

How to solder wires without a soldering iron

Soldering technology is often used to join various alloys and metals. It involves the use of special equipment that is capable of providing a targeted thermal effect. In the absence of a soldering iron, soldering can also be carried out, for which special tools are used, for example, a soldering iron. Let us consider the features of such a process in more detail.

Using a homemade sting

To save money, many craftsmen decide to create a homemade tip. The operating principle of the soldering iron is quite simple:

There is a heating element that receives power from the power supply.
Heat is transferred to the sting, which has a pointed shape.
When the tip comes into contact with the material being processed, it heats up and becomes plastic.

You can make a homemade design as follows:

A piece of copper wire is required, which has a diameter of about 0.5 cm. A conductor can be used as a tip, one end of which is sharpened at an angle of 45 degrees. A small piece of fabric that is temperature resistant is also required.
One end of the cable is insulated. It will be used as a handle. Fiberglass is often used as an insulating material. Fixation is carried out using heat-resistant glue.

Soldering without a soldering iron can be carried out using a fire source, for example, a gas stove. Using fire, the tip is heated, after which you need to touch the solder or rosin. Due to the use of a special material, the tip will become tinned and the tip can be used as a soldering iron.

Solder the garland using improvised means

Problems often arise with garlands that are used to decorate a home or tree. Due to the use of thin wires, they are often interrupted and soldering is required. Among the features of this work, we note the following points:

In most cases, the problem occurs in the control unit, since the wires are not attached securely.
A breakthrough may occur along the entire length of the product.
If all light sources are connected in parallel, then the failure of only one leads to an open circuit of the entire circuit.

It’s quite easy to find loose contacts, but a break is only possible when using a tester. Only after finding the break point can you start soldering. You can solder without a soldering iron as follows:

The broken wires should be cleaned.
You can make a small twist on which the paste is applied. It will be used to distribute the alloy used.
The next step is to melt the solder, which can be done using a lighter or a candle.
After this, the junction is isolated using a tube, which is also slightly heated to increase its ductility.

Similar technology can be used to restore the condition of headphones. The soldering procedure does not take much time.

Soldering wires without using a soldering iron

Wires are prone to breakage. You can solder a wire without a soldering iron if you take into account several recommendations:

To begin with, the break point is located and the ends are cleaned.
After this, the wires are twisted together to create a strong connection.
The area being treated should be slightly warmed up. To do this, you can use a lighter or other heat source.
The solder is also heated to a plastic state, after which it is applied to the joint.

When working with large-section wires, you should grind the solder and sprinkle it on the surface, then heat the surface with a candle or lighter. In this case, the solder fills the free space, thereby ensuring reliable contact. When considering how to solder without a soldering iron, you should take into account the fact that only wires with a diameter of 2 mm can be processed in this way.

Soldering wires without a soldering iron

If you need to solder a flat element, then the parts are pre-tinned. At the time of soldering, the core is pressed and sprinkled with shavings of the selected alloy, after which the surface is heated.

Materials for soldering wires without a soldering iron

In general, we can say that the soldering procedure without the use of a special device is in many ways no different from the usual one. For this you may need the following materials:

Solder directly.
A restrictive element that will prevent the metal from spreading.

In addition, you need to pay attention to the process of cleaning the surface being treated. It is recommended to clean it of dirt and then degrease it.

Features of soldering in the groove

If you need to process wires with a diameter of up to 3 mm, you can do without a soldering iron; grooves are used for this. They can be made from aluminum foil, the thickness of which is 0.8 mm. Recommendations for soldering at home in this case are as follows:

Insulating materials are removed.
The damaged ends should be twisted together and then laid parallel.
A groove is made from foil that will cover the joint. It is used for solder distribution. It is recommended to use shavings.
The foil trough is heated with a candle or lighter. In this case, you need to be careful, as molten metal may leak out and cause burns. When working, it is recommended to use pliers.

If necessary, solder that has leaked out can be protected with sandpaper. The use of foil significantly increases the degree of insulation.

Soldering utensils or containers

Often there is a need to carry packs of dishes and other containers. Without a suitable soldering iron, work can only be done if the hole has a diameter of 6 mm. Among the features of the procedure, we note the following points:

POS60 is used as solder. This alloy is characterized by more attractive performance characteristics; the created patch can withstand significant mechanical stress.
The area around the defect is cleaned. It is recommended to create a surface that resembles a funnel.
Treatment is carried out using hydrochloric acid. It is able to remove all contaminants from the surface being treated.
It is recommended to place a plate on the reverse side that will prevent solder from leaking out. After the alloy hardens, the plate is removed.

Solder POS-60 1mm

As before, the solder should be made with shavings that fill the hole. After this, the problem area is heated using a lamp or other heat source.

Solder paste for soldering without a soldering iron; application features

There is a special paste on sale that can be used as solder. In addition, you can make it yourself. Among the features of the work carried out, we note the following points:

The area being treated is cleaned. The insulation is removed from each wire. After this, it is necessary to degrease, since soot may remain on the surface of the veins.
Using a brush or other similar tool, apply the paste. It is worth considering that it must be distributed evenly over the entire surface of the connection. The brush is selected depending on the cross-section of the wire.
The area where the paste was applied heats up. To heat up the solder, a hair dryer or a homemade sting or a regular lighter can be used as a heater. It is necessary to ensure that the substance does not boil, as this can lead to a change in its basic properties.

Soldering paste without a soldering iron

The composition of the paste you create yourself may vary somewhat depending on the area of application. After exposure to high temperature, the paste becomes a solid material that is resistant to mechanical and other stress.

Foil as a soldering method

The soldering method using foil is characterized by practicality. Typically, it only takes 5 minutes to restore the connection. Foil can be used as solder, which is unwound over the entire area and heated to a high temperature. Due to this, the plasticity of the material increases significantly; after cooling, it hardens.

Foil can be used in a variety of cases. An example is damage to the board or wire connection. Among the features of the work carried out, we note the following points:

Standard contact preparation is carried out.
The ends are twisted to form a joint. Due to this, the reliability of the connection is significantly increased.
The required amount of foil is cut off, the junction is wrapped in several skeins.

After this, uniform heating is carried out using a hair dryer or other heat source. When exposed to heat, the surface of the foil quickly becomes soft and plastic; after heating stops, it quickly cools and hardens, providing the required degree of sealing and strength.

In conclusion, we note that without a soldering iron it is almost impossible to carry out jewelry work, as well as soldering circuit boards. This is due to the lack of possibility of directed heat exposure. However, in some cases a soldering iron and other tools are not required.
