How to make a welding corner

Making a corner clamp with your own hands

The welding process is labor-intensive and time-consuming. In order to make work easier and faster, there are special devices such as angles, stops and clamps. In this article we will talk about corner clamps for welding and how they can be made at home.

What is a clamp?

A clamp is a universal device that is used to secure metal structures in a certain way, which greatly simplifies the welding process.

Angle vices allow you to secure a metal structure at a certain angle in the required and - no less important - in a comfortable position for work. The designs of clamps can be varied depending on how exactly the part needs to be secured. They can come in different sizes and shapes.

It is always useful to have several options of clamps on hand, since during work you may need to fasten parts of different configurations.

Design

There are a huge number of clamps that differ from each other in shape, size, and the task they face. For example, a clamp for working with pipes is designed for welding the latter at various angles, for example, 90 degrees. Without the use of clamps, maintaining the exact angle when working will be difficult. Angle clamps are produced in different types, based on the width of the pipes being fastened and the angle at which these pipes will be welded.

Angle clamps differ in the following characteristics:

• thickness of sponges. The thicker the clamping jaws, the more securely the pipes are clamped and the welding seam does not bend or break.
• material for making clamping screws. During welding, molten metal can be thrown in all directions, and clamping screws are no exception. If molten metal gets on the screw threads, soldering may occur, which will render the thread unusable. To avoid this, copper-plated screws are made. Copper does not allow splashes to harden on the surface of the screw, thereby maintaining its performance.
• working surface. A clamp can increase the working area when working with the electrode at a certain angle.

The angle vise for pipe welding consists of a moving part and a main part. To regulate the degree of compression, the moving part is equipped with a screw. With its help you can adjust the distance between the clamping jaws and the part. The mobility of the structure ensures work with parts of various shapes and cross-sections.

When choosing a clamp, you should pay attention to the type of work being performed. For example, G - clamps are used when working with steel parts of small thickness. To work with parts of large thickness, F - clamps should be used.

DIY corner clamp

The cost of the clamp on the market is high, so it makes sense to make an angle clamp for welding with your own hands. For many, this task will be feasible, because such a retainer can be made even from garbage that has been lying in the shed for years and which, as a business owner, is simply a pity to throw away.

Corner clamps are simple in design, which allows you to make them even at home.

The first step is to make a sketch or drawing of the fastener, put the main dimensions on it, this will help with further work. When choosing a material, you should pay attention to iron. Iron is the best option.

1. In order to form the base, sheet metal of 8 to 10 millimeters is required. For fixation, you can use a corner of the desired size. It is much better to make the connection by electric welding.
2. We make a screw clamp. You can take two nuts and weld them together. A bracket with a central threaded hole is made within 30 - 40 millimeters. It is better to do the fastening with bolts, so that it can be changed in case of thread failure.
3. It is important to pay great attention to the position of the clamping lips. The angle must be maintained perfectly, otherwise the desired 90-degree angle will not be achieved during operation. First, you should weld one corner to the clamp, to which the second corner is applied. Afterwards, all this is pressed and welded to the bracket.
4. Guides must be installed along the side surfaces of the clamp so that the inner base can move. A groove is cut out along the bisector of the retainer being manufactured within 8 - 10 millimeters
5. Next, you need to tighten the bolt into the upper base of the clamping device being manufactured. It is better that the threads on the bolt do not reach its head, this will allow the bases to move freely in relation to each other.

It is possible to make a more movable version of the clamp, where the parts being welded will be pressed not only at an angle of 90 degrees. The pressing angle can be adjusted.

Finally

Based on the above, the use of clamps can make the welder’s work easier, relieving him of the constant need to adjust the parts to be joined several times in a row. Angle vices are easy to make at home, which will save money on their purchase. Homemade clamps are in no way inferior to factory models and are quite capable of competing with them.

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

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.

1. 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.
2. If you often have to weld parts at different angles, it is recommended to purchase an adjustable holder or a set of several triangles.
3. 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:

1. A triangular blank is marked on a metal sheet using a square and some sharp object.
2. Using a grinder, the workpiece is cut strictly along the intended stripes.
3. The cut blank is applied to a metal sheet and the sheet is marked again.
4. An exact copy of the previous part is cut out.
5. Both triangles are filed with a file so that their side planes are perfectly even and the parts are absolutely identical.
6. 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.
7. A magnet from the speaker is placed between the two triangles, onto the plane of which glue is first applied.
8. The square is placed in such a way that the holes of the plates are aligned and they are fixed together with rivets.
9. 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.

Devices that help weld parts at an angle

The reliability of metal structures depends on the quality of welding work. Therefore, there are state standards that regulate welding processes.

For example, GOST 23518-79 determines what should be the connections of parts welded in a shielding gas environment, and how to weld at an acute or obtuse angle. Depending on the gas used, the type of electrode, and additive, the requirements for the welding process are established.

To comply with the technology, devices are used that prevent parts from changing their position, making the welder’s work easier. Such devices help maintain a right angle or any other.

Electrode tilt

To weld parts at right or acute angles, you must be able to move the electrode correctly. During the welding process, the end of the electrode melts along with the coating, which releases protective gases and partially turns into slag, which also protects the weld pool from atmospheric oxygen.

It is necessary to ensure that the bath is constantly covered with liquid slag, otherwise a high-quality weld will not be obtained. The metal must remain in a liquid state for at least three seconds, which is required to release harmful gases.

In this case, it is necessary to move the electrode along the seam, making complex rotational or zigzag movements with the end of the electrode. Such control over welding can only be achieved with the correct angle of inclination of the electrode. But the tilt angle is needed not only to control the welding progress. It can be used to influence the characteristics of the weld.

Welding at an angle forward makes the penetration depth smaller, while the width increases. This can be used when welding thin metals. With this method, the edges are well fused and the welding speed increases.

When welding at an angle backwards, the penetration becomes deeper and the seam is higher, but the width decreases. The edges do not warm up enough, so lack of penetration and the formation of pores are likely.

But the ability to cook is not enough to obtain a high-quality weld. Sometimes a certain position in space is required to make a good seam.

And this is achieved by using special devices that fix the parts to be welded in space as required by the welder. For example, when electroslag welding it is required to position the seam vertically.

When welding, it is often necessary to secure the parts to be joined together so that the welder can do his job. If the products are heavy and have complex shapes, then you cannot do without special devices.

In small workshops, universal type devices have become widespread, capable of fixing the assembled product before welding and changing its position during the work. They come in installation and fixing types.

Installation and securing mechanisms

More practical to use are mechanisms that perform both functions at once - secure and install the workpiece in the required position. In this case, the part is simply installed in the fixture and clamped. Next comes the welding of the workpieces.

The simplest device in design is a device for welding perpendicularly connected products. The base of the device is mounted on a welding table.

If these are large products, then a lattice frame is made and placed in a horizontal plane. The products to be welded are placed on its surface at right angles to each other. For this purpose, there are guides in the form of corners on the plane.

If you need to weld one or more products at right angles, you can fix them using screw clamps (clamps) . It is easier to start welding any connections at right angles on a welding table.

When laid on the table, the correct arrangement of the parts in one plane is guaranteed. A corner rectangular clamp helps maintain a right angle between the parts. The parts are secured in several places by welding, after which the whole product can be rotated as needed for the next operation.

When welding volumetric products, it is necessary to make rotary clamps. This speeds up installation and removal of the product.

Homemade retainer

If the workpieces are small, then a device for securing them at an angle of 90 ° can be made independently from available material. You need to take a metal corner, a strip (two pieces) and two clamps. To set a right angle, you will need a square; no other tool is required.

The length of the corners can be any. The strip is welded at an angle of 45 degrees to each corner so that they form an isosceles right triangle.

Moreover, the corners (legs) do not reach the vertex of the triangle by several centimeters. This will allow you to safely weld rods or profile pipes at the joint in the future. If necessary, clamps can also be welded to the corners. They will firmly fix the products being welded.

In order to prevent the structure from moving, you first need to grab it in four places and only then boil it completely. The resulting device, when secured to the table, will last for more than one year.

Application of magnets

When welding at home, it is convenient to use magnetic clamps. They are electromagnetic and based on permanent magnets. Electromagnets are used more in production. For household needs and small industries, latches with permanent magnets are convenient. They are compact, can be installed anywhere, and some have a variable angle of fixation.

The simplest in design and most common are magnetic squares. It is enough to apply the square to the part to be welded with one plane, and accordingly position the second part to obtain reliable fastening at a right angle.

It remains to grab the parts in several places. After this, the product is completely welded. Without tack, magnetic angles will not withstand temperature deformations during welding.

In addition to squares, there are universal magnetic devices. They can fix the welded products in many positions.

As an example, consider the MagTab device. The device has two main planes with magnets. The angle between the planes changes, so the device can be mounted on a cylindrical, flat surface or in any corner.

There are two more planes to which the parts are attached. The planes are located at right angles and have the ability to move relative to the base. This makes it possible to install the product to be welded in the position that is required.

If you have powerful permanent magnets, especially neodymium ones, you can make such devices yourself. When using magnetic fasteners, you need to take into account that they lose their strength when exposed to high temperatures, so you need to avoid overheating them.

Pipe connection

Welding is often used when pipelines need to be connected. In this case, the question often arises: how to weld one pipe to another pipe perpendicularly.

If profile pipes of rectangular or square cross-section are used, then everything is very simple. At the junction, in the pipe to which the other will be welded, it is necessary to make a cutout for the cross-section of the product being cut into.

After this, they need to be installed in an angle clamp and clamped with a screw, or in any other device that ensures a perpendicular connection of the parts. Then tack is done in several places and then everything is boiled all around.

When welding round pipes, everything happens exactly the same. Only additionally, at the end of the welded pipe, a cutout is made with a radius that matches the radius of the main pipe. This ensures a good joint, which will allow you to get a high-quality seam.

Adapters are often used to connect plastic pipes at right angles. The part is called a 90° angle. It allows you to quickly and easily ensure the accuracy of the angle of rotation.

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.

Clean Water Welding Gadgets

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:

1. 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.
2. 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.
3. 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.
4. 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.

Angle clamp for welding. The seams are pleasing to the eye

Seemingly simple welding work, as a rule, requires a fairly professional and responsible approach. Because to perform high-quality and reliable work, you will need special tools. Such a tool can be an angle clamp for welding, which makes it possible to carry out welding work much easier and faster.

An angle clamp is a kind of universal clamp that holds the surfaces being processed during welding. Such a device firmly compresses the necessary elements at a certain angle and thereby makes the process of welding and processing materials more convenient .

This is the first most important equipment for any welder, and it is impossible to do without it without causing damage to productivity and extreme inconvenience in work. Clamps can come in different sizes and shapes. Quick-release options are considered especially convenient.

In general, for constant welding work, professionals recommend having a set of clamps of different configurations.

Design of corner clamp for welding

Clamps are often available in several modifications and are designed for welding metal pipes at a certain angle (from 30 to 90 degrees). They can be manufactured in different types depending on the width of the pipes, their number and welding angle.

Distinctive features of any corner clamp are:

• jaw thickness – the clamping jaws are thicker to increase the rigidity of the joints. As a result: the welding seam does not bend during welding;
• material for making the clamping screws - during the welding process, molten metal particles often splash out and settle on nearby surfaces. If it gets on the threaded parts, they may become soldered and, as a result, the clamp may fail. To avoid this, copper or copper-plated clamping screws are installed on them. Copper, in turn, prevents splashes from sticking and increases the service life of welding equipment;
• working surface – for working with electrodes at the required angles at the places where parts are joined, the clamp increases the working area.

The clamp itself consists of a moving element and a main frame. The moving part is usually equipped with additional special clamps - a screw or lever that regulates the degree of compression of the parts. Using a moving element, the distance between the tool and the jaws is controlled.

Due to the maximum mobility of the device design, the clamp can hold materials of different sizes and cross-sections. And when using several corner devices, you can form any arrangement of structures for more comfortable and efficient welding.

Most clamping elements are designed for welding material with a maximum diameter of 390 mm .
The angle clamp for welding has a T-shaped handle, which allows you to transfer the clamping force generated during operation to the workpiece.

And cast iron staples can withstand even the highest heat during welding work.

When choosing a corner-type clamp, it is necessary to take into account the type of work planned. So, for example, G-clamps are usually used to fix workpieces of small thickness. If you need to install thick metal products, you should use an F-shaped corner clamp equipped with an adjustable clamping element.

The clamp can be installed in any type of premises in workshops or garages on a work table with a flat surface.

Making a clamp with your own hands

Most models have a standard mounting angle of 90 degrees, but devices with the ability to change the angle are also available. Their cost on the market is much higher, so sometimes it makes sense to make the structure yourself.

The corner type clamp is quite simple in its design and for many it will be easy to assemble it even at home.

Iron is considered the optimal material for making a homemade clamp.

To make your own clamp, you need to do the following:

1. Create the base of the structure - to form the base of the device, it is advisable to use sheet metal with a thickness of 8 mm to 10 mm. The fixing element will be a corner of the required size. It is better to fasten parts using electric welding, since threaded fastening will be less reliable.
2. Install the clamp - to make a screw clamp, it is recommended to use 2 or 3 nuts that are welded together. In this case, it is better to make a bracket with a central threaded hole with a thickness of 30 mm to 40 mm. It is fastened with bolts so that in cases of thread failure it can be changed.

1. Form an angle - special attention in an angle-type clamp must be paid to the location of the clamping brackets. When welding, the corners must fit perfectly one to the other. For these purposes, one of the corners is welded to the clamp, onto which the second corner is then placed, pressed and welded to the bracket.
2. Check the movement of the base - it is necessary to install guides along the side surfaces of the structure that will allow you to move the internal base of the clamp. To do this, a groove with a width of 8 mm to 10 mm is cut along the bisector of the corner device.
3. Drill holes using a drill in the upper base of the clamp, into which a bolt is installed, tightened with a nut and washer. The movement of the bases in relation to each other should be free, so it is better that the threads on the bolt do not reach the head. The head can also be mounted on the base using a bracket.

During the operation of such a standard version of the clamp, due to the limited position of the device at a right angle, sooner or later the question may arise about its narrow focus in operation. This can be corrected by placing a detachable bolted connection in the place of the previously stationary element. As an option, a clamping adjustment screw can be installed, thanks to which it becomes possible to select the required angle and then fix it.

Taking into account all of the above, it should be remembered that in order to obtain a professional welding joint, you need a high-quality tool that allows you to simplify the work and prevent the occurrence of mismatches and adjustments.

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.

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.

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.

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.
