Magnets for welding

Corner magnets for welding: varieties, features when choosing a corner for welding work

Welding, like any other creation process, takes little time when compared to the duration of preparation. The correct location and fastening of the necessary elements is of great importance, since the quality of the work performed depends on it. To facilitate the processes of both preparation and welding itself, special fasteners were created.

Types of fastenings

If the structure after assembly falls apart after the slightest load, it will be a shame, because time and materials have been wasted. After this, all that remains is to get to work again.

The second option for poor preparation is improper welding . Let's assume that the element was welded differently: it changed its place when the metal cooled or changed its shape. This is much more difficult to fix.

It is to avoid such bad situations that special devices have been created that greatly facilitate welding and preparation for it - a switchable magnet for the welder. Since there is a lot of work to be done, the fastenings are grouped into several types:

• Installation. They can be considered basic devices - they help to correctly outline and install the necessary elements.
• Fastening devices. Reliably fix the elements in the required position.
• Fastening and installation. At the same time, they help install and secure parts in the required positions.
• Clamps. Used for fastening metal parts.
• Clamps. It's simple - if the parts are small, it's easier to use them rather than other bulky devices.
• Spacers. Helps align parts.

Magnets for welding

Welding magnets are classified as fastening and installation devices. They are able to install the element in the right place and secure it there in the required position. The strong magnets used in these devices help in this and are the reason for the name.

pros

The mounting triangle has a number of undeniable advantages that allow it to be used in certain situations in the best way:

• It's easy to connect two parts. And it’s easy both in terms of time and effort.
• Fixed angles. The most common angles are 45, 90 and 135 degrees. However, there are parts on the market with any required angles.
• Less time spent. By connecting 2 parts using a magnet, you can immediately begin welding them without wasting extra time.
• Small sizes. Due to the simplicity of the design, they do not have bulky parts and are easy to use.
• Magnet activator. Particularly advanced devices are equipped with a magnetic field switch, which makes them even easier to install or remove.
• Easy to clean. The collapsible design makes it easy to clean the magnets from contamination.

Minus

As elsewhere, corner magnets have not only pros , but also cons . The main problem is the impossibility of their use for some materials. For example, wood or metals with antimagnetic properties.

Varieties

There are two main groups of magnets for welding metal structures: angles and universal devices.

As the name suggests , angles are the simplest in design , which is why they are the most popular on the market. Easily attach 2 parts at the required angle. The angle depends on the shape:

• swept - 45, 90, 135 degrees;
• triangular - the same values ​​as arrow-shaped magnets;
• hexagonal - angles of 30, 60, 75 degrees have been added to the standard values ​​of arrow-shaped magnets.

Universal devices boast great possibilities for use. Magnets and parts to connect them can create any possible angle. The connecting parts have different shapes, so the connection angle is selected with high precision.

Naturally, the main advantage of universal devices is their large range of angles and the ability to repeatedly reconfigure the device. With a simple design and, accordingly, simplified operating requirements, magnets have a wide range of capabilities. Therefore, they are most often used, and not clamps, for example.

Features when choosing

As with the purchase of any product, you can choose a model with the same functionality and quality, but cheaper, without overpaying for the manufacturer’s brand .

• Almost all models do not affect the welding arc in any way. However, the cheapest devices can negatively affect the final welding result, so it is better to avoid purchasing the cheapest devices.
• Magnetic field power. The characteristic is simple - the stronger the field, the heavier elements it can hold. The most powerful devices have field power that allows them to hold objects weighing 35 kilograms.
• Number of corners. This is also a simple characteristic - the more there are, the more angles you can select in the device. For example, having purchased a magnet for welding at an angle of 90 degrees, you will have to buy an additional device if you need a different angle.
• If you have a sufficient budget, you should purchase a switchable welding magnet, since the ability to manipulate the magnetic field greatly facilitates manipulation of the device.
• If you need to weld complex structures, you should immediately think about purchasing universal devices.

In general, magnetic welding angles are a really useful and convenient device, which is very convenient to work with even alone. But we should not forget that low-quality devices can ruin the entire structure, so you need to approach their purchase wisely.

How to use magnets for welding?

Reading time: ≈5 minutes

Any professional welder will tell you that for a high-quality result of the work it is necessary to perform many preparatory operations. Clean the metal, set the welding mode, calcinate the electrodes. But many people forget about another important stage - joining the parts and fastening them together.

But the result of the work also largely depends on the correct docking. You can make a perfect, high-quality seam, but this work will be pointless if the parts are joined crookedly or with gaps. To solve this problem, special devices for welding work were invented. For example, magnets. But magnetic docking holders are not the only heroes of our article. You will also find out what other devices exist for fixing parts.

Types of devices

As we wrote above, various clamps for welding work have been invented to help welders. The most popular of them are clamps, clamps, spacers and magnets. Welding clamps allow you to fix two parts so that they are motionless relative to each other. You can use homemade clamps. Welding clamps can be used to secure small parts. And with the help of spacers you can align the parts.

Magnetic welding devices stand apart. They are the most convenient and easy to use. Let's talk about them in more detail.

Magnetic latches

A magnetic clamp (also known as a magnet for welding, a magnet corner) is a small device for conveniently fixing parts. Welding magnets provide fairly accurate joining, comparable to centralizers. But at the same time, the magnet is much smaller in size and more convenient to use. With their help, you can do the docking yourself.

Many beginners have many questions regarding welding magnets. We will try to answer the most popular ones.

Is it possible to fix parts at different angles?

Yes. A magnetic welding square can be used to join two parts at any angle. You choose the angle yourself; it can be either 130 degrees or 40 degrees. It all depends on the capabilities of your magnet. There are magnets with adjustable angles on sale.

How convenient is it to use a magnet?

Very comfortably! The magnetic mounting square not only saves your time, but also allows you to join parts without unnecessary stress. You only need one small device. No need to use bulky, heavy fasteners or clamps. The magnet fits in your pocket and can be used in any conditions.

In addition, welding magnets do not require special maintenance. They are durable and easy to clean from dirt.

What if I can't remove the magnet from the metal?

If you doubt your abilities, you can buy magnets that have a manual switch off of the magnetic field. Such devices are even easier to install and remove than conventional magnets. In addition, you do not have to spend extra effort and time on dismantling. Turning off the magnet takes no more than a second.

But there must be at least some shortcomings, right?

And it couldn’t have happened without them. The main disadvantage is the inability to work with diamagnetic metals. Such metals are not attracted by a magnet, which means the magnetic clamp simply cannot join the two parts. In addition, such devices are not cheap and many people prefer to use more traditional devices. For example, clamps. And after that make temporary rivet seams. But we consider these methods ineffective and labor-intensive.

Types of magnets

There are two types of magnetic welding holder: angular and universal.

A corner magnet (also called a “magnetic welding corner”) is a simple device that is used to join two parts at an angle. Often corner welding magnets have a fixed angle. For example, you buy a magnet for welding at a 90 degree angle. Accordingly, you will not be able to join parts at a different angle.

But we do not recommend purchasing only one right angle welding fixture. It is better to buy a set of magnetic welding clamps for joining at different angles. The Archimedes magnet has proven itself well for welding at an angle. It is switchable. Switchable magnets for welding are very convenient to use, they fix parts well and work flawlessly.

Universal magnets can be used for welding at any angle. This is the best option, but it is not cheap. But universal magnets can be used with parts of any size and properties. And once you buy them, you will no longer have to buy other magnets. Typically, a universal magnet consists of moving parts fastened together. These parts can be folded into any desired shape and used in your work. Because of their appearance, such magnets are nicknamed “snake”.

Instead of a conclusion

A magnet for welding work is an indispensable device when joining any metal structures and forming high-quality welded joints. Using magnetic clamps you can simplify and speed up your work. This is especially important when performing complex tasks, for example, when welding profile pipes.

Magnets save a lot of time and generally make the welding process much more productive. Therefore, we recommend that you purchase a set of magnets and try them in your practice. The set is not that expensive, but it saves time and effort. Share your experience in the comments below. We wish you good luck in your work!

Magnets for welding

Quite often a situation arises when the preparatory work before starting welding procedures takes much more time than the welding itself. The lion's share of time is spent on stable fixation of all equipment, materials and parts.

If you neglect the stable fixation of all the necessary elements, then the quality of the final result, even despite the high level of qualification of the master, will leave much to be desired.

In order to facilitate the preparatory work before welding associated with the fixation of all working elements, special fasteners are used.

Classification and main purpose

Very often, fastening materials and parts before welding is done using improvised objects. This design is very unreliable; it can fall apart literally from one touch of the filler material.

The unfortunate welder has no choice but to start the preparatory procedures from the very beginning.

However, much worse situations occur when the fasteners become loose or completely destroyed during operation, after the filler material has melted and welded to the working surface.

Professionals in their field, in order to avoid the situations described above, use specialized fasteners that can significantly simplify the preparatory procedures before welding and not be afraid of disturbing the fixation of materials and parts during the welding process. On the modern market of equipment for welding work there is a fairly wide range of different fasteners, which are divided into several main types:

• installation fasteners - their purpose is to install working elements in the required position;
• fasteners - with the help of these products, materials and welding equipment can be quite easily fixed in the required position;
• installation and fastening parts - this type combines the two previous types in one product;
• clamp - this type of fastening will allow you to fix the working surfaces of metal products relative to each other in the required position without any problems;
• clamps are used when working with small products and metal parts;
• spacers allow you to align already fixed parts as required for welding procedures.

Magnets

Magnets for welding work belong to the category of installation and fastening products. With their help, you can simultaneously install the part and fix it in the desired position without any problems. This possibility is achieved thanks to fairly powerful magnets that are located in the internal structure of the fastener.

Advantages and disadvantages

Regardless of the main purpose of the products, there are no products that would be ideal. Magnets for welding are no exception, but they have an impressive list of advantages and only a couple of disadvantages. The advantages of the product include the following factors:

• no need to use fixing elements; thanks to magnets, installing and fastening the part in the desired position does not take much time and effort;
• a wide range of models, each of which allows you to fix the element at a certain inclination and angle;
• thanks to the use of magnets, preparatory work lasts much less than using alternative fixation methods;
• the simple design of the product allows you to easily fix the parts in the required position;
• High-end models have a switch that allows you to turn the magnetic field on and off;
• Magnets for welding consist of only a few parts, making their cleaning process very simple.

There are only two disadvantages:

• availability in the assortment only in specialized stores;
• impossibility of use for non-metallic parts (wood, plastic, etc.).

Classification of magnets for welding work

Magnets for welding work belong to the category of installation and fastening products, in turn they are divided into two types:

• universal purpose products;
• squares.

It is worth considering both types in more detail.

Corner Magnets for Welding

Models included in this category are the most common among welders. There are various versions that allow you to fasten two parts relative to each other at a certain angle. The number of possible options depends on the type of welding angle magnet. They can be divided into three groups:

• arrow-shaped - such products allow you to fasten parts at three different angles (35, 90 and 135 degrees);
• triangular shape - unlike the product described above, this magnet has a triangular shape, but also allows you to fasten parts at the angles specified in the previous paragraph;
• in the shape of a hexagon - as the name suggests, this type of square allows you to secure parts in six different positions (30, 45, 60, 75, 90 and 135 degrees).

Magnets for universal welding

As you can understand from the name of the product, it is universal in use. They differ from squares in that they can be used to connect two parts together at any angle. This possibility is achieved thanks to the ability to adjust the working angle of the magnet. It can be used for cylindrical, angular and flat shape parts.

If we draw parallels with products that have a specific purpose, for example, clamps or clamps, then universal magnets outperform them in all respects. Using the magnet is very easy and does not take much time.

How much do welding magnets cost?

Naturally, the higher the quality of the product and the wider its capabilities, the higher the price it is sold at. During the purchasing process, you need to choose the model whose operation will involve all the functions, since it makes no sense to overpay for various “bells and whistles” and not use them.

The specific price of a welding magnet depends on several points:

• Manufacturer country;
• brand;
• type of magnets;
• maximum possible fixation force;
• angular adjustment range (applies exclusively to universal-use products);
• the ability to turn on or off the magnetic field of an object.

As you can understand, the specific price of a product depends on many factors, so it is not possible to name it exactly.

How to choose?

Many people have a question: “How to choose the required magnet model for welding?” By following a short instruction, it is very easy to find the answer to this question. You need to choose a magnet for welding as follows.

• You need to make sure that the product has absolutely no effect on the welding equipment. Almost all models satisfy this point, however, budget products produced in the Celestial Empire can disrupt the stability of the welding arc.
• Required field power. Naturally, the higher this value, the better. However, along with the increase in strength, the cost of the product also increases. The most powerful representatives are capable of holding parts weighing up to thirty-five kilograms.
• Number of possible fixation positions.
• Possibility of turning on and off the magnetic field.
• Is the magnet model a universal type?

Naturally, like goods for other purposes, welding magnets can be sold at exorbitant prices solely because of the manufacturer’s brand, bright appearance, etc. It is not worth spending a significant amount on purchasing this product if it will be used extremely rarely.

Welding magnets are products that can significantly facilitate both the preparatory work before welding and the process itself. With their help, fixing metal parts to each other does not cause difficulties, and the welding process can be performed alone.

Homemade magnetic welding holder

To perform high-quality welding work in compliance with established safety rules, in addition to special equipment and protective equipment, experts recommend the use of additional devices. For example, magnetic holders are effectively used to facilitate welding of products. With the help of such a square, work is performed with maximum precision, much more accurately and takes less time.

Types of magnetic holders

Today, the welding equipment market offers various modifications of magnetic holders, which differ not only in shape, but also in their operating principle:

• Magnetic square . This is the simplest monolithic special design. welding fixtures, which provide the ability to position the workpieces to be welded at a certain angle.

• Magnetic clamp . This device is flexible and allows you to set any desired angle.

• Retainer . Such devices can be either monolithic or complex configurations, with an adjustable angle. A special feature of this holder is the “fastener release” function. When you press the button, the action of the magnets weakens, as a result of which the device is quite easily rebuilt. The switchable magnetic clamp can be used quite effectively when working with powerful corners.

Advantages of using magnetic squares

• The assembly of individual structural elements is carried out before welding. Thanks to this, labor costs are minimal; one welder is enough to carry out welding work.
• Thanks to the use of magnetic corners for fixing the metal samples to be welded, the welder’s hands are “freed”, welding of products becomes much easier, and productivity increases accordingly.
• Such devices are simply necessary when performing significant volumes of welding. They will greatly facilitate the work of the welder and reduce the time required to complete the work.
• Such holders allow you to accurately fix the parts to be welded at the desired angles, after connecting which you get a very neat and durable weld.
• Fixing the metal samples to be joined using holders can be done not only on a horizontal, but also on a vertical surface.
• These fixtures are also effectively used for non-standard shaped products.

Making magnetic clamps with your own hands

Necessary materials:

• Sheet metal, up to 3 mm thick
• Dry board
• Magnets
• Fasteners

Before you start making a magnetic holder for welding, you need to decide on the design of the intended product. It is better to initially take monolithic structures, a template for which you can create yourself or find on the Internet.

Step-by-step instruction

1. Using a pre-prepared template, 2 plates are cut out of sheet metal. It is important to preserve their geometric parameters.
2. The central part of the magnet is prepared. A part is cut out of wood to match the shape of metal plates.

   In this case, the dimensions should not coincide completely; it is necessary to make small indents from the edges, that is, after assembling the holder, the magnet should be buried several millimeters between the metal plates. The thickness of the wooden blank is taken to be 2 mm larger than the width of the magnets.

3. The magnets are placed between the plates so that the total thickness is no more than 5 cm. It is recommended to use round-shaped magnets; others with holes for self-tapping screws are also possible, with which they will be attached to the structure.
4. The device is being assembled.

   Metal plates are attached to the wooden blank on both sides, and magnets are installed in the grooves. Self-tapping screws are used for fastening.

The magnetic holder for welding work is ready for use.

Magnets for welding: functions and advantages, types of devices and self-production

Today there are quite a few types of welding equipment . Often, various holders and clamping elements are used to secure workpieces. The presence of such additional devices is especially important for those cases when it is necessary to fasten two parts at different angles.

What are magnets for welding? Fastening workpieces by welding may require the performer, for example, to position the elements being processed at a certain angle on one surface. Magnets are very useful when processing profiled pipes. You can improve the quality and convenience of welding work by using various holders and angles.

Often craftsmen use the following devices:

1. Magnetic welding angles (detachable or permanent);
2. Fastening elements (for fixing the position of the workpiece);
3. Clamps (used to clamp certain parts);
4. Spacers (designed to create gaps).

Features and Benefits

The advantages of these devices include the fact that with their help you can save time on preparing products for welding. These details allow you to:

1. Reduce work complexity. The workpiece is secured very simply.
2. Ability to hold the workpiece in any position.
3. The small dimensions of the device greatly simplify the work.
4. Automate welding. Magnets make it possible to quickly disconnect or connect the fastening element.

The simplest products have simple welds, but often they have complex seams and configurations. The accuracy must remain at a high level.

Such welding magnets are characterized by a very simple design. A pair of metal plates with a magnet between them. The most common form is that of a house with a roof and a trimmed ridge. There are other, more complex options for processing products in all three areas.

Magnetic holders can be switched off or permanent. These devices make it possible to fix elements by simply turning them on.

They are good because the locking can be stopped by simply turning the corresponding switch. This also makes it easier to clean the magnetized surface from small pieces of iron and shavings.

Also, magnet angles are universal and standard.

Magnetic clamps

These structures allow you to pull elements together, temporarily fixing them. The most common form is in the form of a “P” symbol laid on its side. One of the sides serves as a permanent lock, and the other is equipped with a screw clamp. The dimensions of the workpieces that are fixed with clamps are limited only by their characteristics. It is very simple to use - the elements are located inside the structure, after which they are tightened with a threaded screw.

Pipe spacers

If you need to make small gaps between the surfaces being processed, then you can make the simplest version of a spacer from a piece of reinforcement or pipe. However, to save time on this procedure, you can purchase a factory product.

The essence of this device is also based on a screw. But this design works by expanding, not compressing.

Making a switchable magnet

The cost of magnetic devices varies from twenty dollars for the simplest devices. Universal type models, of course, will cost a little more. The most expensive devices include switchable magnets, but they can be made with your own hands.

So, to do this you need to do the following:

1. Cut plates from a steel sheet, for example, in the shape of a triangle. The corners must be clearly marked and measured. The end parts must be cleaned with a file.
2. You can get a magnet from any unnecessary acoustics (from columns).

That is, the metal plates must be cut in accordance with the dimensions of the magnet. Then the structure is assembled. The magnet is placed between metal plates, in which holes are made in advance for the location of the clamping bolts.

To prevent the magnet placed inside the device from becoming contaminated with metal scraps and shavings, plugs can be made. The holder can be given any shape, the most important thing is to clearly maintain each of the corners.

Magnets designed for welding activities will be useful to any welder. Even if the master has an assistant who supports the workpieces being processed, it is impossible to achieve the most accurate parameters and angles.

Holders based on magnets will firmly hold the elements, and their installation and dismantling is very simple and does not require a lot of time from the performer.

Magnets for welding: types, advantages, tips when choosing a product

Quite often, the welding process takes much less time than preparation. Usually what takes the most time is fixing all the elements in the desired position. This is the most important point, since the quality of the work performed depends on it. Special fasteners for welding will help make this task easier.

Types of fasteners and their purpose

It’s a shame if, after a long installation and fastening of the elements, the entire structure falls apart at the touch of an electrode. All that remains is to reassemble the entire structure. However, the most unpleasant situation occurs if the element is welded, but not as needed. For example, it became deformed or moved while the metal was cooling.

To prevent such unpleasant situations, special devices were invented to facilitate the welding process. In the modern world there are many different products and they are all divided into several categories:

• Installation devices - allow you to install the element in the desired position.
• Fastening devices - fix the part in a certain position.
• Installation and fastening products - allow you to install and fix the part in a certain position.
• Clamps are necessary for fastening metal parts together.
• Clamps - used for small metal products.
• Spacers - used to align parts.

Advantages of magnets

Magnets for welding belong to the group of installation and fastening devices. That is, they allow you to install an element and fix it in a certain position. This is ensured by powerful magnets installed in the product.

Why are these devices so good? Let's figure it out.

• Simple and fast fastening. To connect 2 metal parts, you don't need to fiddle with them for a long time.
• Possibility of installation at a certain angle. As a rule, magnets allow you to fix products at an angle of 45°, 90° and 135°. There are models that, in addition to these values, allow you to install the part at an angle of 30°, 60°, 75°, etc.
• Reduced time consumption. Significantly less time is spent preparing for work.
• No bulky fasteners. Magnets for welding are not distinguished by their large dimensions or complexity of design and operation.
• Presence of a magnetic field activator. Some models have a switch that turns the magnetic field on or off. Thus, the welding magnet can be easily installed or removed.
• Easy to clean from dirt and chips. Most products are dismountable, so you can easily clean the magnet from dirt.

The main disadvantage is that it cannot be used with certain materials , such as wood or anti-magnetic metals.

Types of products

All magnets for welding can be divided into 2 categories:

• squares;
• universal devices.

The first option has the simplest design and the most popularity. With these welding products, you can easily secure 2 parts at a certain angle. The range of available values ​​depends on the shape of the magnet itself:

• arrow-shaped (the ability to install parts at an angle of 45°, 90° and 135°);
• triangular (similar to the previous one);
• hexagonal (30°, 45°, 60°, 75°, 90° and 135°).

Let's move on to the second group. As the name implies, universal devices have greater functionality and application possibilities. The principle of use is quite simple: using magnets and connecting parts, an angle with the required degree is created. The connecting parts can have a flat, angular or cylindrical shape. Thanks to this, you can fasten 2 products in a non-standard position , for example, at an angle of 27°.

The main advantage of such welding devices is the ability to fix parts at a non-standard angle. If we compare universal devices with other products, for example, with clamps, then magnetic varieties have much more capabilities coupled with ease of operation.

Cost of magnets for welding

As you know, the more bells and whistles a device has, the higher its cost and the more carefully you should choose the appropriate model.

The exact cost of a welding product depends on a number of factors:

• Exporting country.
• Manufacturing company.
• Type of device (square or universal device).
• Adhesion forces.
• Possibility of installing non-standard angles (applies to universal devices).
• Presence of a magnetic field activator.

Therefore, it is impossible to guess the exact cost. However, by visiting some online stores, you can determine the average price for certain products.

The arrow-shaped and triangular varieties have the lowest cost (approximately from 400 to 800 rubles). This is justified by the fact that there are many manufacturers from China on the market for such models.

An honorable second place in cost is occupied by hexagonal shapes without a magnetic field switch (from 450 to 900 rubles).

Third place is given to universal devices. The price range for these varieties is from 500 to 1600 rubles.

The most expensive products for welding are carbon-shaped devices with the ability to turn on or deactivate a magnetic field (cost from 2200 to 3400 rubles).

Some tips when choosing a magnet

It is recommended to purchase magnetic products after careful analysis. For example, why buy an expensive device if it will be rarely used, and the main markup is for a well-known brand? Therefore, when choosing a magnet, you should use a few simple rules.

1. Influence on the state of the arc. Almost all models do not have any effect on the welding arc. However, the most budget products (especially from China) may not have this property. Therefore, it is not recommended to buy the cheapest model.
2. The greater the magnetic field power, the better. The best varieties can easily hold objects weighing 35 kg.
3. Number of corners. Similar to the previous point - the more, the better.
4. If finances allow, it is worth purchasing a device with a magnet activator.
5. If it is necessary to weld complex structures, it is recommended to buy universal fixtures.

Magnetic products are quite interesting devices. They allow you to install and fix the metal part without difficulty. Thus, you can weld alone , without the help of a second person. However, purchasing a low-quality or unsuitable magnet can destroy not only pleasant emotions, but also the metal structure.

Magnets for welding metal structures: varieties

Welding, like any other creation process, takes little time when compared to the duration of preparation. The correct location and fastening of the necessary elements is of great importance, since the quality of the work performed depends on it. To facilitate the processes of both preparation and welding itself, special fasteners were created.
