How to make a magnetic welding holder

How to assemble a magnetic corner for welding 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.

What types of clamps are there for welding work?

There are quite a large number of additional devices for fixing workpieces. They are not mandatory items for a welder, but they greatly facilitate the work and improve the quality of the resulting connection .
Important! It should be noted that the concept “magnet” can include various devices.
Next we will look at devices of various configurations.

Square corners

Magnetic corners are the simplest type of product for fixing parts to be welded at the required angle. The main advantage of such devices is a reduction in the time spent on preparatory procedures, as well as a reduction in the labor intensity of the process.

The holders have a simple design - two metal plates with a magnet between them. Therefore, the possibility of failure is extremely small. Compact sizes make working with them simple and convenient. The performer has the ability to fix parts at almost any angle.

LEOPARD

• Magnetic square BARS MF-75 is designed for fixing metal structures during welding, soldering, assembly and installation, suitable for marking and branding various parts, as well as for demagnetizing tools.
• The device is used to work with round and rectangular pipes, strips, profiles, angles, sheet, solid and other forms of metal.
• The main material - iron oxide (Fe3O4) is capable of attracting the product with a force of 75LBS (34 kgf).
• Angles: 45, 90 and 135 degrees.
• Weight – 1000 gr.
• Dimensions: 155 mm. x 100 mm. x 16 mm.
• Advantages: reliable fixation of workpieces; excellent replacement for heavy clamps; allow you to free the welder's hands; quick collection of metal shavings; facilitate installation; reduce work time; various mounting angles.

Below is a promotional video, but it gives a good idea of ​​the possibilities offered by this type of equipment.

Why is it better to buy a set at once?

Manufacturers and suppliers sell welding magnets individually. Most welding work is carried out on quadrangular structures . Therefore, it is recommended to purchase a complete set of holders - 4 pieces. Having a kit will allow you not to be distracted from work.

For complex structures, a much larger quantity than 4 pieces may be useful.

Mass holders

The ground holder (other names: ground terminal, ground clamp) is a necessary device for the welder. The ground terminal will eliminate the possibility of electric shock and will guarantee a reliable and high-quality connection.

The industry provides various types of mass contact devices : clothespin, magnetic clamp, clamp and centralizer.

Let's consider the pros and cons of magnetic representatives of this type of equipment (all mass clamps are discussed in more detail in a separate article).

Regardless of the type, holders have the following important advantages : ease of use and speed of work. It should also be noted the advantages of magnetic holders :

• used for fixing workpieces of various configurations, sizes and diameters, in contrast to the “clothespin” type;
• successfully used in hard-to-reach places;
• reliability of fastening is ensured due to the large contact area with the workpiece;
• simplicity of design and absence of complex elements ensure a long service life;
• withstand significant loads and stress.

Disadvantages of magnetic holders:

• “magnetic blowing” effect and arc deflection;
• impossibility of use for working with products made of non-ferrous metals;
• if the magnet is non-switchable, various debris sticks to it, so it should be cleaned periodically;
• overheating, which occurs when the mass is attached to a dirty or rusty surface, can lead to demagnetization;
• inconvenience of attaching a magnet to small workpieces: rod or fittings.

The advantages and disadvantages of other types are presented in the article “Mass clamp”. [ads-pc-2][ads-mob-2]

PROFI

• The magnetic grounding terminal PROFI is designed for connection to the grounding of the welding cable.
• The magnetic base provides excellent attachment to metal surfaces of various shapes.
• The device provides reliable contact at the connection points.
• A small contact area eliminates the possibility of overheating.
• The handle allows you to easily remove the terminal from the part.
• Weight – 400 gr.

Torch holders

The holder is a support with a magnetic base , used for storing MIG/MAG and TIG torches. The device holds the equipment when not in use.

The use of such holders allows you to avoid the possibility of damage to the burner, increase the service life of the nozzles for it, and also increases the convenience of performing work.

It is especially important to use holders when storing gas burners, since their nozzles crack when they come into contact with the cold surface on which the equipment is placed.

The magnetic base guarantees the stability of the structure , which can be placed on a welding table or can be attached to a working device.

ESAB

• A simple and practical holder suitable for most burner models.

Magnetic welding mirror

The welder's magnetic mirror is designed for inspection and quality control of welds , making it easier to carry out work in hard-to-reach places .

The magnet allows you to attach the mirror to any metal surface without holding it in your hands. Most models have a flexible tripod (leg), which allows you to rotate the device at any angle.

Welders are offered other types of welding mirrors, which will be analyzed in a separate article.

CIMCO

• Country of origin: Germany.
• Long lasting magnet.
• Flexible brass rod with swivel joint.
• Weight – 460 gr.
• Length – 500 mm.

Switchable and non-switchable devices

Magnetic holders for welding can be permanent or switchable . The second type is attached to parts by turning on a magnetic field activator.

Such devices have the following advantages in comparison with conventional magnets: quick removal is carried out with one turn of the switch; the ability to turn off the magnetic field makes it easy to clean the device from chips and other small debris. The only drawback is the higher cost .

Foxweld SHIFT-7

• The switchable magnetic square is designed for pre-assembly and fixation of parts during welding, cutting (prevents parts of the structure from falling) and installation, and is also suitable as an element for holding workpieces.
• Easy to use, allowing one person to do all the work.
• The device is suitable for any work with metal objects.

Main selection criteria

For professional work, you should choose a high quality tool. Devices are exposed to high temperatures, which reduce the magnetization coefficient of low-quality specimens. The fixture must be free of chips, gouges and other defects where it touches the clamped product. Irregularities do not allow objects to be firmly fixed at a given angle.

• Important! The advantage of switchable corners is the ability to turn off the magnetic field both on the entire device and on its individual faces. These devices are suitable for craftsmen who often weld parts of complex configurations

Chinese angles have a budget price, but they cannot withstand temperature changes, so they quickly break. To weld products at different angles, it is recommended to choose a customizable mechanism or purchase a kit containing several types of tools for clamping at certain angles.

Dimensions

Magnetic devices are small in size , which makes them so popular. The length, width and height parameters of equipment with magnets may vary, but regardless of the model and manufacturer, they are all compact and easy to use. The average weight of the product is about 1 kg.

The most important indicator is the force of attraction (holding or pressing) of the magnetic corners. Manufacturers and suppliers may specify this parameter in pounds (LBS or lbs) or kilograms (kgf). The maximum value of this indicator is 34 kgf or 75 lbs. You can also find the following values: 11; 13; 22; 23; 24 kgf and others.

Important! The higher this parameter, the heavier the parts the magnet can “hold” and the better the fixation. To make a purchasing decision, you should not take into account dimensions in centimeters; it is better to look at the force of attraction.

Depending on the tasks, you should choose the necessary model. [ads-pc-3][ads-mob-3]

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.

With your own hands

Some craftsmen like to create devices themselves rather than buy an industrial version. For such performers, below are instructions for making all types of accessories with magnets. We do not encourage you to copy the instructions and videos below, but rather consider them as suggestions for ideas.

Square - holder

Magnetic corners for welding work have a fairly simple design, so making such a product with your own hands is easy. The master will need a metal sheet 2-3 mm thick; magnet; fasteners: screws and nuts.

Manufacturing algorithm:

1. On a metal sheet, using a ruler and a felt-tip pen, you need to draw the outline of the future product. The shape can be different, but the most optimal configuration is triangle and trapezoid.

Important! The corners should be as straight as possible.

2. Using a grinder, you need to cut out two blanks of the same size and shape, then sand them on the end and front sides.

Important! The angles of both plates must match.

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.

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.

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

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?

1. Allows you to work with round pipes, rectangular cross-section, sheet metal and products of complex shapes;
2. 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;
3. Quick fastening, unlike clamps, just lean the corner against the parts and it will fix itself;
4. 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;
5. The device can work in any planes, at any angle and on any surfaces;
6. 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.

Types of magnetic holders for welding

Models existing on the market can be classified both by form factor and operating principle. For example:

1. A magnetic square of a monolithic design is the simplest type of product that allows you to position the workpiece at one of the provided angles.

2. Magnetic clamp is a flexible tool that can be adjusted to any angle.

3. Latch – can have a monolithic form or a complex design with variable angles; its feature is the function of “disabling” the fastener. By pressing a button, the magnets are weakened and the device is very easy to rearrange, which is especially useful for powerful magnetic corners for welding.

Also, angles are divided according to power into standard ones, in which the simplest magnets are used, and for particularly heavy structures, magnets with a high degree of retention are installed in them.

Reference! Magnet power is expressed in kilograms and is assigned to each similar product.

Cost is not the last parameter, which directly depends on the capabilities and quality of the magnet. For domestic needs, devices of simple monolithic structures with low holding force can cost from 300 rubles. More complex moving products of similar power will cost 500 - 1000 rubles. Finally, the most expensive monolithic, clamp-type holders, with powerful magnets, will cost 3-5 thousand rubles.

We recommend! Do-it-yourself resistance welding from a microwave

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.

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.

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.

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.

How to make a magnetic corner for welding

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.

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.

Do-it-yourself magnetic angles for welding - Website about

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.

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.
