Do-it-yourself magnetic corner for welding - Metals and their processing

Types of magnetic corners for welding. How to make a holder with your own hands

When welding small metal parts, it can be difficult to keep them stationary. To fix the elements in this case, the welder most often has to resort to the use of additional mechanisms and devices so that the parts do not move during welding.

The use of vices and clamps allows them to cope with this task perfectly, but the main disadvantage of such products is the need to carry out a large number of additional movements to install the part in a static position. And also the inability to fix parts at a certain angle.

A magnetic holder for welding does not have such disadvantages, so if you often have to weld parts in this way, it is recommended to purchase or make this device yourself.

Types of magnetic holders for welding

When performing welding work, magnetic devices of the following designs are most often used.

Angular: permanent

The advantage of this model of angles is the ability to quickly fix the parts to be welded in 6 positions. The device consists of 2 plates with a powerful magnet located between them.

If you often have to weld parts at different angles, it is recommended to purchase an adjustable holder.

A design with fixed angles will be much cheaper, but such a device should be purchased when the main part of the welding work involves fixing elements in the most frequently used position.

Disabled

The switchable magnetic welding holder is a device in which the magnetic field can be neutralized using a rotating lever.

Such devices cost several times more than a regular angle, but thanks to the shut-off function, using the product is easier and more comfortable.

Also, switchable models can be easily cleaned of metal shavings and other small parts.

Watch an interesting video where a person talks about a homemade switchable magnet for welding:

Which type of welding holder to choose depends on many circumstances. If the corner is needed for frequent use, it is recommended to purchase a switchable model with a tearing force of at least 20 kg.

Main selection criteria

If a magnetic holder is needed for professional use, then it is difficult for a beginner to understand the models on the market.

Below are the main criteria for selecting such a device, taking into account many factors.

Purchasing a low-quality product will complicate the performance of welding operations at a high level. The holders are exposed to high temperatures, which can lead to a significant decrease in the magnetization coefficient of poor products. When purchasing, you should inspect the product for mechanical damage. Even a small recess or unevenness of the tool at the point of contact with the fixed elements will not allow the work to be performed at the required angle.
If you often have to weld parts at different angles, it is recommended to purchase an adjustable holder or a set of several triangles.
Not the last selection criterion is the price. The cost of many Chinese-made models can be very attractive, but often such devices fail after the first use.

To purchase a high-quality magnetic holder, it is recommended to consider products made in Russia and Europe.

Homemade magnetic corner

If you don’t want or have the opportunity to purchase a fixing device in a store, you can make it yourself from scrap materials.

A magnetic holder for welding with your own hands can be made using the following materials:

magnet from a powerful speaker;
steel sheet 2.5 mm thick;
heat-resistant glue for metal;
rivets.

To carry out the work you will need the following tools:

A homemade magnetic holder for welding work is made in the following sequence:

A triangular blank is marked on a metal sheet using a square and some sharp object.
Using a grinder, the workpiece is cut strictly along the intended stripes.
The cut blank is applied to a metal sheet and the sheet is marked again.
An exact copy of the previous part is cut out.
Both triangles are filed with a file so that their side planes are perfectly even and the parts are absolutely identical.
The triangles are aligned with each other, clamped in a vice, and holes are made at their corners with a diameter equal to the thickness of the rivet used.
A magnet from the speaker is placed between the two triangles, onto the plane of which glue is first applied.
The square is placed in such a way that the holes of the plates are aligned and they are fixed together with rivets.
Once the glue is completely dry, the product can be painted in any color using special heat-resistant enamel.

The assembled product will allow you to qualitatively fix a mass of up to 3 kg at a certain angle.

If a more powerful holder is required for welding work, then the device can be made according to the above diagram. Only use neodymium magnets from a computer hard drive as a magnetic material. In this case, you can get a free and high-quality device with increased power.

When making a homemade structure, using glue and rivets is the best option. If you use bolted connections, then over time the fastening will weaken due to vibration and high temperature.

Conclusion

Using magnetic angles for welding allows you to perform work more efficiently.

The cost of non-adjustable models with the ability to place workpieces in 3 positions will be about 500 rubles, so every welder can afford to purchase such a product. If you want to save money and improve your DIY skills, then the instructions provided will help you make a magnetic device with your own hands.

Magnetic corners for welding

Welding work requires maximum precision. It is convenient to secure structural elements in a certain position using a magnetic welding square. Manufacturers make magnetic fixtures for welders of various designs. They come with permanent and switchable magnets and differ in the load they can withstand.

Magnetic corners for welding

For welding work, magnetic holders with a certain size of corners are used. They produce universal designs with regulators; they secure the support bars to any angle. For home welding, craftsmen make their own compact squares from scrap materials.

Purpose of magnetic squares

The preparatory work takes a lot of time, the workpieces being welded must form a joint, to achieve this, sometimes you have to call an assistant to attach a clamp. With a magnetic welder's square, the procedure is simplified.
The quality of the seam and the geometry of precise structures depend on the fixation of metal parts in a static position. In this case, you have to use clamps; their installation is an obligatory part of the technological process.
With a square, you can securely fix metal parts together without any tools.
It is difficult to mark metal when working at heights or in confined spaces. Making markings using corners is much easier.
With magnetic devices, the welding process is accelerated, labor costs are reduced, this is the economic component of using the angle.
The devices are easy to use: just lean them against the metal, they won’t move.

They are securely fastened in any conditions, in a vertical, horizontal, inclined plane. Often used for horseback riding: elements secured with a magnet do not need to be held with your hands, they are protected from falling.
When using squares between the parts of the structure to be welded, the welder gains freedom of action, and there is no need to tack the parts before surfacing the main weld.

When using angles between the parts of the structure to be welded, the welder gets freedom of action

Advantages of using a magnetic square for DIY welding

To obtain a high-quality product as a result of welding, having only experience, professionalism and dexterity is not enough. It is also important to have all the necessary equipment (welding equipment, personal protective equipment, etc.), as well as auxiliary tools for work.

They allow you to simplify and speed up the welding process, and the finished seam will be of higher quality and neater. Any professional should know how to do their job better using such auxiliary tools. One of them is magnetic corners.

They can also be called welding magnets, a welding square, or a magnetic do-it-yourself welding square.

These tools are designed to hold metal parts and pipes during the welding process, soldering and assembling products. An experienced craftsman will no doubt find use for this useful part in other areas of the economy.

Magnets for welding: advantages of use

They are used when working with round and rectangular pipes, metal sheets, and non-standard shaped parts.
The welding angle can be of standard sizes, for example, 30, 45, 60, 90, 135 degrees. Also, a magnetic corner for welding can be universal and be adjusted to any required angle.
On-the-fly fastening: The magnetic welding holder is fixed to the part independently.
The ability to work without the help of a partner, that is, labor costs are reduced to a minimum. This factor is especially important if there is a large amount of welding work to be performed.
Angles can be used in any location of the parts to be welded and at any angle.
Magnetic holders can also be used to mark any elements.

Currently, for an increasing number of welders, magnetic angles have moved from the category of auxiliary tools to the category of necessary ones.

What types of fixing angles are divided into?

Division into types can occur for various reasons. According to the source of their occurrence, they can be divided into factory corners and homemade ones. Of course, for professional use it is better to purchase angles from well-known manufacturers. For one-time uses on the farm, it is better to use a homemade magnetic holder, which is much cheaper.

You can make a magnetic square for welding from steel by first drawing drawings. The plates can be hand poured or laser cut.

There should be a spacer between the plates that prevents the sticking of metal filings and gives the product more rigidity. It can be made, for example, from plywood. Aluminum rivets and glue are used to assemble all the elements together.

As a result, we get a magnet for welding with our own hands. If everything is done correctly, it will be similar to the factory counterparts.

Magnets are also divided into types depending on the configuration and principle of operation:

The conventional holder design allows for a fixed angle setting.
The magnetic clamp is characterized by the ability to adjust any angle, which allows it to be used for work of any complexity.
The clamp can have a permanent and switchable magnet for welding. The last view is automatically switched off after welding is completed. That is, you don’t need to make any effort to remove it.
Most modern clamps have multiple angle settings, making them applicable to a wider range of welding applications.
Corners come in different capacities. To fix bulky, large and heavy parts, you need to use more powerful magnets, and light elements are welded using low-power magnets.

Thus, the importance of using magnetic corners for fixing products is very high. They simplify the work and allow you to do it more quickly, without the help of a partner. There are many manufacturers of magnets in different price ranges.

It is important that the simple design allows you to make a magnetic square with your own hands, thereby minimizing material and labor costs during the work process.

All of the above facts speak only about the positive qualities of this auxiliary material.

How to make your own magnetic corner for welding

Clamps for welding are presented in a wide range, there are about 10 types in total, not counting the options for self-production. Some of them have a narrow purpose or are primarily used in the woodworking industry, so not all are suitable for welding work. Among all models and their varieties, a magnetic clamp is widely used. Its operating principle is very effective, since modern magnets with high efficiency can be used.

Another significant advantage is that you can make a magnetic corner for welding with your own hands, adjusting the size and power to your needs.

Magnetic welding square

Device and principle of operation

Important! When making it yourself, you need to use heat-resistant magnets, which perform their function when the steel is heated above the Curie point. For carbon steels, which are highly weldable, this temperature is about 1000 °C

A magnetic square is a device for welding at right angles, unlike a clamp, it has only one angle and is not adjustable. In shape, this option repeats the corner clamp, but with the difference that the first one does not have a moving part, as it is unnecessary: the fastening function is performed by a magnet.

The production of these models became possible with the advent of neodymium magnets, as well as their variety - switchable ones. The adjustable range of thickness of the parts being fastened replaces the power of the magnet. The square itself provides good fixation to the surface due to its rigid body.

When purchasing holders online, incidents often occur. The most common of them, which directly or indirectly affect the quality of work performed:

The plates on both sides are not centered properly. This leads to distortions of the welded structure, instability of the angle on the surface and inaccuracy of the seam.
The magnet is not powerful enough, i.e. it does not correspond to the declared one. As a rule, this is a removable defect, since it is enough to add a few more elements to the surface.

Buying from branded stores has the disadvantage of high cost. This is especially expensive if the tool is not used often.

Tools and materials

Let's look at how to make a magnetic angle for welding yourself. The most important advantage of such a product will be that for its manufacture you will need waste materials, which can be found in any garage. This also applies to neodymium magnets, which today are available both for sale and for independent “mining”.

Components for making a magnetic corner

The tools used can be found in the average workshop. Among the main ones:

Bulgarian. It can easily process non-ferrous soft metal and wood. The only thing you need is special attachments for each material separately.
Screwdriver. Or it can be replaced by a regular screwdriver, since the screws we screw in are small and in quantities of no more than 30-40 pieces.
Drill with a 2-2.5 mm drill. Since the holes need to be made in a metal plate, the drill must be appropriate.

The following materials will be needed:

Aluminum, steel or copper plates. A sufficient thickness of only 2-3 mm. Non-ferrous metal has several advantages: it is easy to machine (unlike carbon steel), and it does not oxidize, so it does not need to be coated with paint.
A wooden block with uniform thickness over the entire area (this is important!). It should be dense solid wood, dried and not damaged by moisture.
A special place is given to magnets. Today, you can purchase the required number of elements on online platforms or in household goods stores. A hexagon or circle with a hole inside is most suitable. They can also be obtained from discarded office equipment.

There are 4 places where magnets can be removed:

pocket headphones, which are used for modern gadgets;
computer hard drive;
computer disk drive;
stepper motor.

When disassembling devices, you need to be careful, since the magnets are highly fragile and can break under slight point pressure.

Step-by-step manufacturing instructions

Important! The corner must withstand high temperature, static (when using large elements) loads, therefore it is necessary to select the thickness of the sheet with a margin so that its weight and strength correspond to the purpose

No welding machine is used during the manufacturing process. This is a fairly simple job that even a novice master can handle. The most important thing that needs to be done correctly is to maintain the exact and identical dimensions of the parts and also join them during assembly.

Magnetic corner assembly process

Choose the shape of the magnet. Most often this is an equilateral triangle: then a magnet is used to weld at an angle of 90 degrees and 45°. To make work easier, the lower part (the base of the triangle) should have a rectangular protrusion of 2-4 cm.

The principle of making a corner magnet. Its components: 2 metal plates. You can use any metal, but non-ferrous metal is better - it is easier to work with and does not oxidize. The most affordable are aluminum or copper alloys. Cutting corners for welding is done with a grinder.

A wooden block is inserted between them, the thickness of which determines the working grip, i.e. stability on the surface, and also regulates the size of the magnet, and, accordingly, its power.

To make them, we will need hexagonal or round magnets, up to 1.5 cm in diameter, with an internal hole for fastening. And we will screw them into the end part of the tree. All cutting work is carried out using a grinder and a screwdriver. We will also need:

screws for screwing in magnets;
sandpaper for cleaning the surface of aluminum;
surface paint if using steel sheet.

Using a square, we mark the future shape on the metal sheet, which is taken as a basis. It is a thick arrow pointer. We do this in duplicate. We cut the corners at the top at a distance of 1 cm from the top and round off the sharp points.

Using a grinder, we cut out and then sand the ends around the entire perimeter.

We treat the surface with sandpaper. If we use steel, we cover it with paint.

In all corners, at a distance of 15 mm from the edge, we drill holes for screws.

We cut out a wooden block; the shape should be repeated, but be 5 mm smaller than the metal parts.

We carry out the assembly. We pay special attention to the alignment of the parts and their smooth edges relative to each other.

The last stage: attaching the magnets. On the end sections we mark with dots the places to which the magnets will be screwed. The distance depends on their diameter. It is more reliable to fasten using screws, so you need to drill holes of a slightly smaller diameter than the screws themselves. After this, the square can be used.

How to assemble a magnetic corner for welding with your own hands?

Small metal objects are difficult to hold in one position during the welding process. Fixation is carried out using improvised means so that the products do not move. A magnetic corner is suitable as an auxiliary tool.

It is also called a welding square. It will be useful for both the home craftsman and the professional welder. This mechanism improves the quality of the weld and the part as a whole. Let's look at how to make a magnetic corner for welding with your own hands.

Magnets for welding

Welding is a fast and reliable way to create permanent connections between metal parts. The process itself does not last long; it often takes a lot of time to correctly position the workpieces relative to each other. They must be fixed accurately and securely so that there is no displacement during the welding process. Many devices have been developed for this. Magnetic fasteners - angles and holders are very quick to install and remove and save the welder a lot of time.

Magnets for welding

Types of fasteners and their purpose

In order for the weld to be strong and reliable, the workpieces to be welded must be fixed. For this purpose, there are many different types of equipment, universal and specialized. These include:

switchable magnets for welding;
screw clamps;
screw spacers;
magnetic corners.

Switchable magnets

In this type of equipment, it is possible to control the intensity of the magnetic field, turning it on and off. This effect is achieved by rotating one magnet inside the housing relative to the other so that their magnetic fields either mutually enhance or neutralize each other, and the field does not pass beyond the housing.

Switchable magnets are placed and removed from workpieces with one finger movement. Such devices are especially convenient when it is necessary to correct the position of workpieces.

Another advantage is that after turning off such a holder, all sawdust, trimmings, shavings and other small metal waste fall off it, making cleaning easier

Switchable magnet

Clamps

The equipment is designed to reliably press the workpieces against each other. Its outer part, made in the shape of a right (or other) angle with a cut out top, is the fixing part, and the inner part, equipped with a screw feed device, is a clamping device. Essentially, this is a vice with jaws bent at an angle. The parts (profile or rod) are placed in a clamp and pressed against each other with a screw.

The dimensions and shape of the parts are limited by the size of the clamp. It can be used not only for welding, but for other plumbing work.

Clamp

Spacers

Spacers are used to create the required gap between the workpieces to be welded. Home craftsmen choose for this purpose cutting pipes and profiles from a waste box, but it is much more convenient to use an industrial product. The spacer is also equipped with a screw and is a “reverse clamp”. It can be adjusted to any required clearance within the screw stroke. Spacers and welding magnets are often used together.

Magnetic corners

One of the most commonly used devices is a corner. Its main advantages:

Reduces the labor intensity of the welding process. The time for fixing workpieces is reduced several times.
Parts can be fixed at almost any angle between them.
The device is compact and does not interfere with welding work.
The time for removing equipment is also reduced several times compared to clamps.

Magnetic corner

Magnetic corners are available with both fixed angles and freely variable angles. To do this, they are equipped with a hinged device with a lock.

Structurally, the equipment consists of two metal plates cut from sheet metal and permanent magnets fixed between them. The most popular are universal flat corners, reminiscent of a house with a cut off roof. But there are also three-coordinate spatial clamps in the form of polyhedra or cylinders. They allow you to assemble very complex spatial structures, such as power line supports, spatial trusses, etc.

Purposes of use

The main goals pursued by the use of magnetic holders for welding work are the following:

convenient and reliable fixation of workpieces;
placing them in space in strict accordance with the product drawings;
precise alignment of angles between parts;
reducing the labor intensity of welding and improving its quality;
replacement of obsolete screw clamps and clamps.

Magnetic corners for welding have a clamping force from 5 to 60 kg and are used with sheet metal and rolled profiles.

According to the degree of versatility, equipment is divided into two types:

universal;
corner magnets.

Universal equipment has one or more degrees of adjustment and allows you to work with workpieces of flat, cylindrical and multifaceted shapes, connecting them at arbitrary angles in several planes simultaneously. Such devices are indispensable when assembling complex spatial structures. They are given increased resistance to heat and splashes of molten metal.

These advantages of professional-grade equipment come at the price of a high price and limited availability in regular hardware stores.

The square is much simpler in design, easier to learn and allows you to cover most of the needs of the home craftsman.

Triangular Welding Magnets Hexagon Welding Magnets

Angles are available in three main forms:

sagittal (“house”);
triangular;
hexagonal.

Arrow-shaped and triangular ones allow you to weld workpieces at angles of 45°, 90° and 135°. Hexagonal, in addition, support angles of 30°, 60°, 75°.

Using magnetic squares when working with simple structures saves even more time than using universal ones. The disadvantage of such devices, especially their budget models, is the low magnetic force.

Advantages of magnets

The main advantages of magnets compared to screw and wedge equipment are:

Easy and quick rough assembly of the structure.
Possibility of fixing parts at the most common angles of 45°, 90°, 135°. Advanced models of magnetic fasteners for welding will allow you to fasten workpieces at angles of 30°, 60°, 75°, and universal ones - at any angle.
Saving time on preparatory operations several times.
The fasteners are small in size and do not interfere with welding.
Switchable welding magnets make it easier to install or remove.
Easy to clean from shavings, sawdust and slag. (especially switchable ones).

The disadvantage compared to screw and wedge fastenings is their inapplicability to wood, plastic and other non-magnetic materials.

Criterias of choice

Before you start buying a magnet for welding, you should think about what specific operations you are going to use it for. In addition, the volume of this work and its frequency are important. If you need to weld the frame of a fence or greenhouse once a year, or replace the trim of a trailer body for a walk-behind tractor, there is no point in buying a professional model with fixation at an arbitrary angle in three planes, but you can get by with a couple of squares.

If you are opening a business and the scope of welding for six months to a year is clear, then a professional device will pay for itself by increasing labor productivity.

There are also several general rules and recommendations for selection:

The higher the class of equipment (and its price), the longer it will retain its working qualities, primarily its geometric dimensions and clamping force.
High magnetic field power allows you to hold workpieces of greater mass or length. Mid-level models hold up to 35 kg.
A larger number of angles will allow welding of a variety of structures.

Modern high-quality devices do not have a negative impact on the stability of the welding arc. Unfortunately, some cheap Chinese holders have this effect on welding quality and are best avoided.

Switchable magnets are several times more expensive than permanent ones. But they are also much more convenient.

It becomes possible to weld without an assistant. With them, it is possible to precisely adjust the position of parts with millimeter precision - just turn off the magnet for a second and move the workpiece. It is also much easier to remove them from the finished product after welding. Another advantage is that when the magnet is turned off, all the iron debris stuck to it falls off on its own. Whether such convenience and performance is worth the money requested is something everyone decides for themselves.

The quality of the switched-off magnet must be high. If it switches off spontaneously during welding, the structure may disintegrate into blanks and the work will have to be redone.

A simple DIY magnetic square

The magnetic square has a very simple structure and is quite accessible for self-production by a craftsman with metalworking skills. Usually they are made by hand in three cases:

testing your strengths and abilities;
There is no suitable size on sale;
for welding non-standard products.

Do-it-yourself magnet for welding

For production you will need:

sheet metal 2-3 millimeters thick;
round magnet (from an old speaker);
bushings made of non-magnetic material (plastic, hard rubber, etc.);
nuts, countersunk head screws.

The manufacturing sequence is as follows:

Draw the outlines of the holder on the sheet. You need to be especially careful and use only a high-quality and certified square and ruler for marking. The accuracy of the assembly of your future structures will depend on the accuracy of the angles when marking.
Using a grinder or jigsaw, cut out the parts and align their edges.
Cut the bushings to size. It is important that they are strictly the same in height and have smooth edges.
Pick up a piece of elastic plastic and fix the magnet along its inner hole.
Mark the places for fastening, drill the plates (preferably together).
Assemble the product by putting the bushings on the screws and placing them and the magnet between the plates.

The clamping force of the product depends on the accuracy of the assembly and the magnetic properties of the metal; before welding, it will have to be determined experimentally.

Magnetic holder for DIY welding

This is another design option for a magnetic corner for DIY assembly. It will require:

metal sheet 1-3 mm;
neodymium magnets (so-called “screw magnets”);
dry board;
nuts, countersunk head screws, self-tapping screws.

Manufacturing of magnetic holders for welding

The manufacturing procedure is as follows:

Mark and cut two identical blanks from the sheet, carefully monitoring the accuracy of the angles.
Make the central part of the holder. Cut it out of the board so that it follows the contours of the metal plates, but recedes inward to the height of the magnets plus a millimeter to one and a half.
Fasten the metal and wooden parts of the product together.
Using self-tapping screws, screw the magnets to the wooden spacer around the perimeter so that they are at the same distance from each other.

Before starting work, you need to check the geometry of the resulting equipment - its angles and dimensions.

How to make a switchable magnetic square

The cost of magnets for welding ranges from hundreds of rubles (household models made in China) to tens of thousands (switchable universal professional devices from well-known brands with the ability to work in many planes and arbitrarily set angles). But it is possible to make their analogue yourself:

Cut two triangular-shaped plates from a sheet of metal (or in the shape of a house with a cut off roof). You need to carefully monitor the exact alignment of the angles.
File the edges.
The magnet can be used from faulty speakers or a microwave oven.
Mark and drill through holes in the corners of the triangle and in its center.
Using four screws and nuts and bushings equal in height to the magnet, fasten the structure so that the magnet is clamped in the center.
To reduce contamination, plastic plugs can be placed along the end faces.

DIY switchable magnet

The shape of the magnet for welding may not be triangular. It is selected depending on the needs of the assembled welded structure.

Welding Magnetic Square

Very often, in order to carry out high-quality welding work, experience alone is not enough. Even professionals use welding aids, such as magnetic welding angles, to help hold parts in place during work and prevent them from moving.

The main objective of this design is to ensure precise joining of two products, most often at an angle of 90 degrees. However, professional magnetic corners allow you to hold parts at any angle.

Advantages of a magnetic angle for welding

Welding magnets allow you to work not only with sheet metal, but also with products of complex shapes.
Thanks to the presence of a magnet, welding work is greatly simplified.
Quickly fix the product at the desired angle.
Welding magnets allow you to work in any plane.

DIY magnetic square

Even an inexperienced craftsman can easily make a magnetic angle for welding with his own hands. For this you will need the following materials:

Sheet metal 2-3 mm thick in section;
Round magnet;
Bulgarian;
Screws, nuts.

Let's look at the step-by-step manufacturing of the product:

Before starting to manufacture the product, it is better to study the diagram of the magnetic square. Professionals recommend that beginners use monolithic products. Templates for such designs can easily be found on the Internet or created individually for yourself. We mark the future product on a metal sheet. It is important that the angles are as straight as possible.
Using a grinder, we cut the workpieces and check their corners.
We replace the cutting disc in the grinder with a cleaning disc and carefully grind the product. All corners of the two plates must match exactly. If something does not match, the corners are adjusted to maximum purity. In addition, both the end and front parts are polished so that rust and other defects do not reduce the strength of the magnetic field.
We fix the magnet between the two plates and carry out the assembly.
We drill out the fastening points and assemble the magnet for welding using screws and nuts. M6 type bolts are used for assembly. The nuts are screwed not only onto the end of the bolt, but also between the metal plates to prevent the product from bending when screwing in the threaded bolt. It is important that the round magnet does not protrude beyond the edges of the templates. The shanks of the bolts that extend onto the nuts must be cut with a grinder.
Checking the distance between corners
The magnetic corner for welding is ready.

When using both homemade corners and store-bought ones, do not forget about the operating temperature conditions. Thus, welding magnesium requires very low temperatures, while other alloys require stronger heating, which can lead to the loss of the magnetic properties of the angle.

The magnetic square is designed for fixing metal parts during welding, soldering, and assembling structures. Used to work with round pipes, rectangular pipes, strips, angles, profiles, sheet, solid and other types of metal. The elbow quickly and reliably connects parts, reduces work time, facilitates installation and replaces bulky clamps and clamps. Angles: 45°, 90°, 135°.

There are many types and designs of welding angles from different manufacturers. For different types of work, magnetic angles are available in different sizes, different strengths, and even with a continuously variable working angle.

Naturally, all welding angles vary in price. But if the brand and appearance are not very important to you, then you can easily make a magnetic square with your own hands. A homemade device is quite enough for welding and installation work in a garage or farmstead, and most importantly, a homemade device is more pleasant and cheaper.

In any case, the welding angle will find its use.

Let's start manufacturing. A store sample of a magnetic square was taken as a basis. Its dimensions were changed to use a magnet, from a speaker, from an old TV. The result is a drawing like this.

The grade of steel can be any, in my case it is steel 3. The plates of the welding angle can be cut out by hand, or with a grinder, the main thing is to maintain the accuracy of the angles. In my case, the plates were cut from metal using laser cutting. These are the blanks we got.

Now we need to make a spacer between the 2 plates of the magnetic square; it is needed in order to protect the magnet from the adhesion of metal filings and give rigidity to our structure. The simplest thing we had on hand was plywood, cut out a blank with a hole for the magnet and reduce the contour of the part by a couple of mm. This is done so that the spacer does not interfere when fixing, for example, a water pipe with a magnetic square.

Now that we have all the necessary parts, we assemble the magnetic square using aluminum rivets, having previously coated the parts with glue for greater reliability. The plates must be assembled strictly in parallel.

When the glue dries, all that remains is to paint the homemade magnetic square, first with a primer and then with paint, in the color you like.

As a result, we get a welding angle similar in its characteristics to store-bought samples. The main thing to remember is that during operation it is undesirable to allow the magnetic square to become very hot, since the temperature can lead to a loss of magnetic properties.

Welding Magnetic Square

The main objective of this design is to ensure precise joining of two products, most often at an angle of 90 degrees. However, professional magnetic corners allow you to hold parts at any angle.

Magnetic fixtures for welding work

Welding equipment, in addition to the device itself and protective equipment, has a more extensive list. Most often, a variety of clamps and holders are required to secure workpieces. The presence of such additional equipment is especially important when you need to weld workpieces at different angles.

In this article we will look at what welding magnets are used in the work process and how to make some of them yourself.

Types of welding fixtures

Why are magnetic accessories used in welding? The technology of joining parts by welding may require the welder, for example, to place different workpieces at angles from 30 to 90 degrees or to precisely orient the edges in the same plane. Such magnets are especially useful for welding metal structures from profile pipes. Excellent quality can only be achieved by using various types of corners and holders.

Most often in welding practice the following devices will be required:

Magnetic corners (permanent and switchable).
Fastening devices (for fixing in one position).
Clamps (used to clamp parts).
Spacers (to create gaps).

Magnetic welding square: how to make a homemade holder with your own hands

Comfort and convenience in any work have never bothered anyone. This also applies to welding. Among the welding tools, there are basic ones and there are auxiliary ones. These include the smallest auxiliary part in size - a wonderful magnetic corner, or, more correctly, a magnetic angle for welding.

Such corners are extremely useful for both artisans and professionals working on stream. Small in size but not in function, these special welding triangles improve the quality of products in general and welds in particular.

How to make a welding square?

Here's how they do it:

While the metal workpieces are precisely and securely fixed, you have more freedom in your actions. Your hands and your attention are concentrated only on the welding seam. Hence the increase in its quality.
Using a magnetic welding angle, you can prepare and perform all welding work yourself, without outside help. That's labor savings for you. And you also don’t depend on anyone.
The seam will be neat and precise thanks to the optimal and reliable installation of the workpieces using corners. If your work requires special precision, then the use of angles becomes not a recommendation, but a mandatory condition for welding.
If you have a large amount of work, you cannot escape without fixing triangles: they will allow you to save your working time to a significant extent.
It is easiest to weld workpieces of unusual or non-standard shapes using a welding angle with a magnet.
With corners you can cook not only on horizontal surfaces, but also on vertical ones.
These squares are useful not only for welding and soldering, but their ability to firmly hold parts is useful when cutting metals.

Types of magnetic squares

Welding magnets can vary in both shape and operating principle:

A clamp is a flexible square with angles that can be adjusted. An excellent tool to help produce parts of any complexity.
A simple welding angle with fixed angles and a permanent magnet.
Switchable magnets for welding are an excellent technical solution for ease of work: after welding, you can turn off their action, the holders “unstick” on their own, which allows you to remove the clamps without effort or any deformation.
Universal magnetic angles for welding with several standard angles are another excellent technological solution for performing a variety of jobs of varying complexity.
Angles with different power of action. It is clear that fastening massive workpieces requires fasteners that are powerful in action, just as for small work that requires jewelry precision, they must be compact both in size and in terms of attractive power.
Three-coordinate and tetrahedral squares using cylinders and ferritic heat-resistant magnets for working in difficult temperature conditions and with workpieces of different sizes and weights.

Choosing the right square: here and now

Dimensions of the square for welding.

Everything is simple here: for simple home welding work, you will need holders that are simple in design. Complex processes involve fasteners with technological bells and whistles - from switchable magnets to heat-resistant options, from simple corners to 3D models.

One way or another, a high-quality magnetic holder for welding must be resistant to significant mechanical loads and have sufficient tensile strength. In the end, we are talking about fixing not fluff, but heavy metal parts. Our squares must be able to fix them completely and irrevocably. Only in such cases will welding holders make sense at all.

If you are engaged in complex welding work, and if you have the opportunity, then it is best to choose high-quality holders with on/off magnets. Such devices will help you turn on or off not just the entire square, but individual edges.

This mode makes it possible to independently work with complex tasks. Corners of this class are usually made of chrome-plated metal with increased strength.

The cost of welding holders cannot be called low; these are not cheap devices. The price depends on the number of standard angles, attraction power, adjustment mechanisms, brand, etc. The simplest copies cost about four hundred rubles, a standard set costs around a thousand rubles. Well, professional magnetic welding devices with technological additions increase in price to 3,000 - 5,000 rubles.

DIY magnetic holder

Working with a magnetic square.

Making your own magnetic corner for welding is a great idea for three reasons:

This is a real cost savings
This will be a device that is suitable specifically for your technical needs.
This is a very simple device, which is quite possible to make even without much practical experience.

What you will need:

a magnet of any shape, but preferably a round one with a thickness of about 15 mm;
steel sheet 2 mm thick;
M6 bolts with nuts.

Welding angle with shut-off.

The tips and steps for making a welding angle are as follows:

This device is best made from steel manually, using a grinder or laser. The main thing is to cut the templates with extremely precise angles on the work plane. There should be two templates. Their size should be larger than the diameter of the magnet. We pay special attention to the size and grinding of the corners - the quality of your square will depend on this. It wouldn't hurt to sand the entire surface well: if rust or any defects remain, the strength of the magnet will decrease.
The magnet will attract any metal debris in the form of sawdust or shavings. You can get rid of this with the help of a spacer - a special part made of steel, which should be slightly smaller around the perimeter than the steel corner itself. Such a spacer will add additional rigidity to the holder, which will not hurt you. A special through hole is made in it.
A magnet can be of different shapes. He is placed inside. Under no circumstances should it protrude beyond the edges of the steel plates. To fix it, you need to make four holes: one in the middle and the other three at the edges.
The final stage of assembly is the careful folding of the layers of our “sandwich”, which can be fixed either with glue or metal rivets. The most reliable way would be M6 bolts. Nuts should be placed not only on the ends of the bolts, but also between the layers. The tails of the bolts protruding onto the nuts must be cut off with a grinder.

Magnetic angle for welding. You just need to choose the degree!

To carry out high-quality and safe welding work, in addition to specialized working tools, hand and face protection, additional equipment is recommended - successfully used by professional specialists and those who weld only from time to time, a magnetic welding square will make the work easier, more accurate and more accurate.

What advantages do magnetic angles provide?

Any additional devices that make the master’s work easier have positive aspects of use. A magnetic corner for welding is an indispensable attribute even for a one-time need, not to mention in-line work performed by professionals:

due to the fact that the metal parts intended for welding are securely fixed, the welder receives greater freedom of action and, therefore, ease of operation;
due to the fact that the assembly of the welded elements is carried out before the actual welding, one person is enough to complete it - magnetic corners minimize labor costs;
when using a magnetic welding angle, the parts are installed accurately, and therefore the completed seam will be neat: when carrying out welding work on high-precision structures, angles are not a recommendation, but a necessity;
when performing a large volume of welding work, such corners are simply irreplaceable - they will significantly reduce the time spent by a specialist on welding;
for parts of non-standard configuration it is also convenient to use magnetic welding corners;
parts to be welded can be securely fixed not only on a horizontal, but also on a vertical surface;
In addition to welding, soldering and other types of work connecting individual elements, magnetic corners will be convenient, for example, when marking or cutting steel - a strong fixation will keep individual parts of the structure from falling.

As a rule, angles from well-known manufacturers have a configuration that allows using one such magnetic clamp to set different welding angles: 45°, 60°, 90°, 135°. A self-made magnetic corner makes it possible to work with almost any angle set to the tool profile.

What types of magnetic angles are there for welding?

Magnetic corners can be different both in configuration, which allows you to set different angles for welding work, and in their operating principle:

a magnetic square for welding of the most common design allows you to set fixed angles determined by the profile of the tool;
a magnetic clamp with adjustable angles is a flexible tool with which you can perform work of any degree of complexity and accuracy, setting almost any angle;
the magnetic clamp can have a permanent or switchable magnet - turning off the magnets after welding allows you to remove the clamp without any physical effort;
most modern models of angles have several standard angles - this design makes this tool universal, allowing you to perform welding work of varying degrees of complexity;
angles also differ in power: to fix heavy elements of global structures, powerful magnets are needed, but tools with low power are recommended for welding compact parts of low weight and are usually used for household work.

The price for each tool is formed based on several indicators: design and the ability to construct several angles, adjustment capabilities, magnetic power, reputation of the manufacturer, etc. The cost of magnetic holders varies widely: from 300-400 rubles for a household copy and 800-900 rubles for a set of standard corner clamps up to 3000-5000 rubles for a professional tool.

How to choose a magnetic angle for welding?

For simple amateur work, inexpensive standard designs of magnetic holders are quite suitable, but for complex professional work and production conditions, three-coordinate (when using cylinders) and tetrahedral squares are intended - made using ferritic heat-resistant magnets, they will provide the necessary power for confident fixation of a wide variety of weights and configurations of elements of the welded structure.

In any case, a high-quality magnetic angle for welding must be designed for heavy loads, have high tensile strength and be resistant to strong mechanical influences from the outside. A square with a certain power must firmly fix the structural elements corresponding to this power in weight and size - only in this case will the welder’s work be comfortable and safe.

To facilitate the dismantling of the magnetic fixing device, it is recommended to choose angles with switchable welding magnets - in this case, even one master can easily and quickly cope with complex work using a special switch (one or two to turn each edge on/off). Switchable corners are usually made from durable chrome plated sheets, and thanks to the working edges they are successfully used in working with various profiles.

Thus, it is recommended to choose a magnetic holder for welding work based on the expected joint angles of the parts, the weight of the tool, its size and power.

Magnetic square for DIY welding

If, for some reason, the range of magnetic angles presented in stores, designed to work with pipes of various sections, angles, strips, profile parts, elements made of sheet, solid and other metals, is not satisfactory, then it is not difficult to make such a device with your own hands. Such an easy-to-use and inexpensive tool will faithfully serve in household welding and installation work at home and in the farmstead. There can be several design methods, the most common and inexpensive is as follows:

As a metal base, plates with precise angles of working planes are cut out of a suitable grade of steel manually, with a grinder or using laser cutting.
To protect the magnet from the adhesion of metal shavings, sawdust, etc., a spacer (for example, made of plywood) is used for additional rigidity of the structure. This part around the perimeter will be slightly smaller (by 3-4 mm) than the plates from step 1; a through hole is made for the magnet.
A magnet of any (most often round) shape is placed inside - it is only important that it does not protrude beyond the contours of the outer plates and has a central hole to allow its rigid fixation.
The assembly process consists of strictly parallel folding of all parts, for greater reliability, treating them with glue and fixing them with aluminum rivets.

When using both store-bought samples and those made independently, you should remember the operating thermal conditions recommended for magnetic devices: high temperature and strong heating of the magnetic clamp can lead to the loss of its magnetic properties.

Magnetic square for DIY welding

Often, skill alone is not enough to carry out high-quality welding work, which is why various auxiliary devices are used, such as a magnetic corner. It is designed for fixing metal parts during welding, soldering or assembling structures, and a good owner will find a dozen more uses for this design.

What are the benefits of magnetic squares?

Allows you to work with round pipes, rectangular cross-section, sheet metal and products of complex shapes;
A good fixture has a number of standard angles - 45, 90, 135, 30 and 60 degrees; there are also universal models that can hold parts at any angle;
Quick fastening, unlike clamps, just lean the corner against the parts and it will fix itself;
Simplification of the welding process occurs due to the absence of the need to use an assistant for the welder, plus the ability to adjust the location of the parts to be welded after they are secured;
The device can work in any planes, at any angle and on any surfaces;
Preset template angles make it easier to work with in-line products.

It is also worth noting that for most welding work, such a part is not just a recommendation, but an integral part of the work process.

How to choose the right model

The first step is to decide how you will use the holder. If you need it for one-time use, then the cheapest option is suitable, which will be useful in the future, but will not hurt your pocket.

For those who regularly work with welding equipment, models with a large number of preset angles and inexpensive universal models that allow you to independently set and fix the angle are suitable.

For professional use or to complete a small workshop, it is worth purchasing a set of magnets with a high degree of retention. Very often, one magnet is not enough to work with, so having a whole, even minimal, set will greatly facilitate the welder’s work.

The next parameter is the holding force. The stronger the magnet, the heavier the parts can be used in the work, the longer it will retain its holding properties and the better it will fix the parts. When buying magnetic welding devices with a high-quality magnet, make sure that you can remove it yourself, or better yet, that it has the ability to “unstick” on its own, that is, it is switchable.

Magnet quality is a parameter that most young welders forget about. Here it is important for us that the magnet can retain its properties for a long time and, more importantly, does not deteriorate when heated. The operation of a welding magnet occurs in close proximity to the welding site, so the entire product is subject to heating, which deteriorates the quality of the magnets.
