Welding work sometimes requires less effort and time compared to preparation for it. Their main part is the assembly of a welded structure, during which it is necessary to fix the elements in the required position. This work requires attention from the master, because the quality of the products depends on it.

If, after careful alignment and installation of the workpieces, the structure falls apart from the touch of the electrode, it will be a shame; you will have to assemble everything all over again. It also happens that an element is welded, but not in the required position. This can occur when there is subtle movement or deformation after the metal has cooled. That is why before starting welding work it is necessary to stock up on all the necessary equipment.

Solution

In order to avoid such mistakes, special welding devices are used. They allow you to save energy and time, ensuring high quality output products. Today there are many known mechanisms and devices that can be used for welding work. If people work in an industrial environment where mass and serial production is established, they use automated and mechanized equipment, this should include stacking mechanisms, transport devices, technological assembly devices, etc. If the master has to work at home, then he can use welding devices, which it is quite possible to make on his own. They will reduce the deformation of parts.

Making a clamp

Without a clamp, which you can make yourself, no welder will be able to cope with the job. In addition, this tool helps solve problems during plumbing and carpentry work. This device can have different options - specialized and universal. Recently, another modification has appeared, which is a quick-release clamp. With its help, you can provide a compression force of up to 450 kg. However, the main task of such tools is to fix the workpieces for interconnection.

Working on an angle clamp: preparation

Welding devices are offered for sale today in a wide range, but you can make an angle clamp yourself. The tools and materials for carrying out the work are:

• steel corner;
• threaded studs;
• nuts;
• drill;
• steel plates;
• rods for gates;
• tap.

Carrying out work

At right angles, the corners must be attached to the steel plates. A worm-type structure is fixed on each side by welding. This is a corner with a welded nut or thickening, in which a thread should be cut taking into account the knob stud. In this case, it is also important to pay attention to the potential workpiece, because it determines the width of the working gap. If the range of part sizes is wide, then it is best to prepare several clamps.

The collar pin is screwed into the working nut, and a stop is then assembled at the end. This design consists of two metal washers of different sizes. It is important to ensure that the stop rotates on the stud. The driver on the reverse side must be equipped with a hole into which a steel rod is installed. It will act as a lever. Such welding fixtures are assembled correctly if they can be used to securely fix steel parts. The design is very simple, and it can be made from scrap materials.

The end face is quite a difficult task. In this case, the workpieces will need to be precisely oriented in space. If a piece of pipe is welded to the finished system, the task will be simplified. But loose workpieces need to be welded with outside help or using a special device. It is necessary to use steel plates and a metal corner during the work. The clamp halves are attached traditionally; for this you need to use threaded rods. As a result, it will be possible to obtain an effective and simple design.

Making pliers

Homemade welding devices also include pliers. You can collect them, but you need to be patient. To carry out the work, you should prepare a copper dart, the length of which is 2 m. Its diameter should be 30 mm. This workpiece may turn out to be slightly longer, in which case it will be possible to bend it. The element is bent to form a horseshoe-shaped blank. 18mm holes are made at the ends, then you need to turn them around and make a cut.

The result will be clamps for the electrodes. Two transformers are connected in parallel, in which the secondary and primary windings must be connected directly. The current supply can be adjusted independently. Such homemade welding devices must be cooled, and water should be used for this. By using the foot pedal you can remove the electrodes.

From the above we can conclude that the pliers contain a lever for turning the electrodes, a transformer, and a handle with a pusher. The lever is held by hinges whose axes are located oppositely. Sometimes pliers are made with a spring between the pushers. However, such a device for welding pipes cannot be called convenient. After all, compressing the spring when turning will be quite difficult.

Making a magnetic holder

If you are interested in assembly and welding fixtures, you can make them yourself, rather than purchasing factory-made options. This also applies to the magnetic holder, for which you need to prepare the following materials:

• sheet metal;
• dry board;

When preparing metal, it is necessary to be guided by certain parameters; the thickness of the sheet can vary from 1 to 3 mm. When creating a template for a future design, it is better to make a monolithic version, the dimensions of which will correspond to the needs of the master. The template must be attached to the sheet metal and identical blanks must be cut out in the amount of 2 pieces. It is important to preserve their geometry.

It is best to draw up drawings of welding fixtures yourself; you can find some of them in the article. The next step on the way to fixtures will be preparing the central part of the magnet. To do this, you need to cut a piece of wood according to the shape of the metal plates, but its size should not completely repeat the template. You should retreat 2 mm from the edges. The thickness of this element should be 2 mm greater than the width of the magnets.

The outer part of the product is ready at this stage, now you need to create the internal filling. In this case, you should push away from the magnets. They will be located between the plates, and the thickness can vary from 10 to 50 mm. When making such a device for welding at an angle, it is better to use round magnets, each of which will have holes in the central part. However, other workpieces can be used for work, which are pre-prepared by cutting holes for installing fasteners. The final stage will be drilling holes and assembly. Steel plates are fastened on both sides with a wooden blank, and magnets are fixed in the grooves. At this point, we can assume that the product is ready; it should be tested in practice.

Making a welding jig

If you need hand tools for welding, you can start making a jig. It is used when making frames and complex patterns. The design has cone-shaped supports that must be placed on the sides. A rotating plane is attached between them. It should have adjustable longitudinal beams with several screw clamps.

There will be holes in the beams, which is why clamps can be installed along the entire length, which will depend on the size of the product. The width of the assembled structure can be adjusted by introducing beams and spreading them apart. The sliding mechanisms of the described device can be used as a universal means for welding small and large products. If you decide to use stainless steel, then when working it is important to avoid scratches that may occur from screw clamps. That is why the latter should be supplemented with felt stickers that are installed on the lips. Such a device can be assembled from a profile pipe; you will need long bolts and bearings, the penultimate of which are needed for fastening the moving parts.

90 degree welding fixture

Some devices allow you to avoid problems when it is necessary to connect parts at right angles. To carry out manipulations to assemble the structure, it is necessary to prepare a metal square, bolts, nuts, a piece of square pipe, a bolt, a small metal cylinder, a drill, a drill bit, a holder, and a welding machine.

When preparing a square, you must take into account that its side will be 20 cm. When choosing a thick bolt, you should prefer one that has 4 cm in diameter. When choosing a metal cylinder, you should prepare one that is the size of a ballpoint pen.

Work methodology

When making the above-described welding device with your own hands, you must weld pipes 15 and 20 cm long onto the square. They must be installed in the corners so that the ends of the pipes are on different sides of the square. Now you can start making auxiliary parts. To do this, a U-shaped figure is prepared from the pipe; its length should be 10 cm. The second part is made from the same pipes, but the elements are welded together in the form of an isosceles trapezoid.

An isosceles triangle is made on the sides of a square. A U-shaped figure is welded to it, in which a hole is first made in the center for a small bolt. A 4cm bolt should fit into the gap between the figure and the square. A handle is attached to the latter; a nut with a hole can act as it. The small cylinder needs to be threaded for small bolts. It is done along the end of a large bolt. At the point of intersection of the trapezoid's diagonals, holes must be made in both parts. A cylindrical element will be installed between them, in which the thread is first made.

Conclusion

To facilitate welding work, you can find a huge number of devices and devices on sale today. A special place among them is occupied by those that can be done independently. Taking into account the information that was presented above, it can be argued that such structures are made from scrap materials and there is no need to purchase anything additional, which is why you need to be patient and prepare drawings.

With the help of such a simple device, you can conveniently weld a metal profile at any angle. As a result, work will be easier and the quality of welding will improve. I think you should spend two dozen minutes and make yourself a little thing that will save you time and effort in the future.

Materials needed

• A piece of steel plate, approximately 30-50 mm wide and 2-5 mm thick.
• A piece of steel plate, approximately 10-30 mm wide and 2-5 mm thick.
• A piece of corner profile.
• Two nuts M4-M8.
• Long stud for nuts.
• A short bolt with a nut of the “Cheburashka” type.

Making a fixture for profile welding

We take a thick plate.

From it we cut out two pieces 140 mm long. We mark along the line.

We cut it with a grinder and sand the sharp edges.

We combine the segments together and drill a hole for the bolt in both.

We insert a bolt into the holes, securing it with a Cheburashka. Using a ruler, set a right angle and tighten with a Cheburashka.

We mark a straight line along the ruler. It is necessary to make such a cut so that the segments, being at right angles, are parallel with their ends to each other and are in the same plane. Cut carefully with a grinder.

This is how it should turn out in the end: the angle is straight, and the legs are on the same line.

We attach the corner profile.

We weld using arc welding.

Approximately setting aside a distance of 90 mm on each side, we draw strips.

Like this:

Cut off the middle with a grinder.

Now we take narrow pieces of steel plate.

We clamp it in a vice and bend it into an “G” shape with hammer blows.

Now we weld it to each side of the future device.

Next, we weld nuts to the bent ends.

We screw a cut hairpin into each nut, with a Cheburashka welded on the end. This kind of clamping mechanism was created on each side.

The device is ready!

Due to the fact that it bends in any direction, you can choose absolutely any welding angle, both blunt and sharp.
We fix the rectangular profile at a right angle.

And if you need to weld pipes evenly, then nothing could be easier. Everything will be fixed precisely and there will be no movement or shaking when welding.

You can fix not only metal, but also wood.

In general, get yourself such a useful and convenient device and you won’t regret it. See you next time! See the video for detailed assembly.

Welding fixtures allow you to fix the parts to be welded in the desired position and with the required welding gap along the entire length of the edges and can increase the productivity of the welder and improve the quality of the weld. In this article, more intended for beginner welders, almost all welding fixtures, methods and options for making them yourself, and other nuances will be described and shown.

Every master, even someone who is not particularly experienced, but who has at least once in his life tried to weld some parts together, understands well that welding itself often requires much less effort, patience and time than preparing the parts for it. And the main share of all welding work is the assembly of the structure itself, with precise and reliable fixation of the welded parts in the required position. Such work requires a special approach and attention, since the quality of the finished welded product depends on it.

In the absence of special welding fixtures, it usually happens that after careful adjustment, alignment and installation of the prepared parts in the position required by the welder, the assembled welded structure simply falls apart at the first touch of the welding electrode. At the same time, you need to have great patience to pull yourself together and put everything back together.

It is also often even more annoying if the parts being welded are still stuck, but not in the position required, because the part moves slightly relative to the other part due to the touch of the electrode, or due to the deformation of the parts after they have cooled. In such cases there is no need to talk about a normal weld seam and normal quality of the welded structure, and it is not so easy to redo everything again. Therefore, you should still spend a little time and money to manufacture (or purchase) specialized or more universal welding devices, and of course this will help any master save his time and nerves, and most importantly, end up with a high-quality welded product.

Almost all welding fixtures operate on the principle of clamping the parts being welded to securely fix their edges in the desired position and with the required welding gap. Welding fixtures may differ depending on what parts they are intended for fixing, on the geometric shape of the parts being fixed, as well as on the holding method - for example, using threaded clamps, using magnets, etc. And since the devices differ from the shape and size of the parts that they fix, it means that they will be divided in this article depending on what parts to be welded they are intended for.

Also, if possible, I will definitely describe (and even show) what and how you can make some welding fixtures with your own hands, and if possible, the manufacture (or manufacturing options) will be described using the most common tools available in the garage, or even at home . And so let's go.

Devices for welding steel sheets.

steel sheet welding device

The most common type of welding is welding steel sheets (especially for cars), and therefore I will start with devices for reliable fixation of steel sheets. When welding two steel sheets together, or when replacing a rotten fragment with a new one (when welding a new fragment), it is very important to align both sheets at the same level and with the same welding gap along the entire length of the edge.

This is the only way to achieve a weld of excellent quality, and only in this way, after grinding the seam, will you be able to use a minimum amount of putty, or do without it at all. This is especially important if subsequently (after grinding and polishing the welded seams) the parts being welded will be coated with another galvanic coating, rather than paint and varnish coatings.

I showed the simplest, but very effective device for precise and reliable fixation of steel sheets welded together in photo 1 and in the video below. There I also showed step by step how to make it in a garage and how it is used. Therefore, I will not describe it here; just click on the video below and see it clearly.

Of course, you can simply pull two sheets by the edges using welding clamps or ordinary clamps, shown in photo 2 b, or using wedge clamps (photo 2 a), or using a threaded rod and corners, indicated by red arrows in photo 2 c ( We also press the corners with clamps or clamps). But it will be more difficult to position both sheets with the same gap along the entire length of the edges.

Welding fixtures for welding steel sheets: 1 - sheet, 2 - clamp, 3 - clamp (can be made from corners and pins, as shown in photo 2c).

And it will be impossible to accurately place a new fragment of steel sheet on the body, to replace the rotted one, using ordinary welding clamps or clamps, especially if the fragment is welded inside a cut-out window in the body panel.

Therefore, in the workshop it will be very useful to have, in addition to welding clamps, a device that I showed in the video and in photo 1.

Devices for welding plates or profile pipes.

DEVICE FOR WELDING pipes at right angles - the so-called corner clamp.

When welding the plates together at the same level, the device shown in the video above will help, but if they need to be aligned and welded at a certain angle, then you will need the device shown in photo 3 - the so-called corner clamp. It will also be needed to align not only the plates, but also profile pipes and angles at right angles. By the way, with the help of corner clamps, you can also set round pipes at the desired angle, but still, round pipes will fix the devices described in the section below better and more accurately.

Nowadays you can find a great variety of corner clamps on sale, but it is quite possible to make them yourself. Homemade simple corner clamps are shown in photo 4, and they can be made from the same profile pipe, corner or steel sheet.

Well, you will also need a nut and a stud, with an M10 or M12 thread. The main disadvantage of the corner clamp shown in photo 3 above is that it can only clamp and weld profile material at a right angle of 90º.

Homemade DEVICES FOR WELDING pipes

If you want an angle clamp that allows you to clamp and weld the material at almost any angle, then you should make one of the designs shown in photo 4. But their rigidity leaves much to be desired and to make a more rigid universal clamp you will have to tinker longer and make a universal one (adjustable) clamp, shown in photo 5, which uses fairly thick metal.

When making such a clamp (as well as any clamp), the main thing is to achieve precise alignment of the planes on which the welded profile material will be laid and clamped.

WELDING DEVICE for welding pipes and plates at different angles. 1 and 5 - U-shaped profile (you can also use a piece of channel), 2 - axle - bolt, 3 - axle nut, 4 - washer with angle marks at 30, 45, 90 degrees, etc., 6 and 7 - wing nuts

Well, the rigidity must be sufficient so that the clamped and subsequently welded material does not lead during welding (from heating).

Welding fixtures for fixing and welding round pipes.

For fixing and welding round pipes, devices are made from prisms, thick sheet metal, or angles. Examples of such devices were shown in photo 4 just above.

Universal pipe welding fixture

If you spend more time and use thick sheet metal, you can make a much more convenient and versatile device that allows you to securely fasten and position the pipes at any angle.

Such a device is shown in photo 6. If desired, you can attach a protractor to one of the plates, and attach an arrow to the second plate, and then you can easily control the exact and desired joining angle of the pipes being welded.

Well, for joining and welding round pipes strictly on the same line (straight sections), a homemade device shown in photo 7 is suitable.

WELDING DEVICE for welding pipes on one line

It is not difficult to make it from sections of four plates, four corners and four bolts with nuts, which will compress and fix the round pipes strictly in one line.

The design of this welding device is clearly visible and understandable in photo 7. By the way, it also shows that to clamp pipes with such a device, you can use both bolts (studs) and welding clamps.

Of course, to weld round pipes on one line, you can use other simple devices, for example, two prisms laid on a table and two ordinary clamps that will press 2 pipes laid on 2 (or 4) prisms to the table.

Welding fixtures for fixing and welding rods and fittings.

To fix a rod or fittings before welding, you can use almost all devices that are designed for pipes. But often it is necessary to weld some kind of spatial structure from a rod and reinforcement, in which to two parts welded together in a horizontal plane and at a right angle, it is necessary to weld another part, which needs to be fixed and welded vertically, and strictly at a right angle. It is quite difficult to do this manually, and in this case the welder will be helped out by the device shown in photo 8.

WELDING DEVICE magnetic corners

However, almost all simple welding fixtures (even with threaded clamps) have the main task of fixing the part for tack welding, and then welding it completely. Any experienced welder knows this, but for beginners it doesn’t hurt to remind them. If there is a need to almost completely eliminate the deformation of the structure from heating, then you should use, or (or a welding table) - but stocks are a completely different topic, which you can read about by clicking on the corresponding links just above.

As can be seen from photo 10, magnetic devices, like threaded ones, can be non-adjustable - capable of fixing parts only at a certain angle, and there are more universal adjustable magnetic devices that can change the angle of fixation of the parts being welded.

For adjustable devices (they are indicated in the photo by 10 red arrows), two planes are fixed on an axis and can change position relative to each other, and after setting the desired angle between the planes, the device is fixed with a wing nut. The angle is controlled using a protractor, after which we clamp the wing nut and install (magnetize) it on two planes of the pipe, which must be welded at a predetermined angle.

Welding table.

Welding tables (along with jigs, links to jigs above) are the most versatile welding devices, allowing you to fix and weld almost any welded structure. There can be many options and designs of welding tables, but the principle of their design and operation is almost the same.

devices for securing parts during drilling (can also be used for milling or welding)

Many universal tables designed for welding metal structures made of thick-walled material have a plate thickness of 50 mm.

The steel plate of the table, of course, must have a perfectly flat surface, and also have many holes (see photo 11) allowing the installation of fastening elements (clamps, clamps, ties, prisms and other parts that are used on milling machines, or (such fastenings) details are shown in the photo on the right).

Rotary welding table. There are also rotary welding tables that allow you to secure a small structure and rotate it in space during the welding process, which makes welding much more convenient and improves the quality of welds.

The only drawback of rotary welding tables is that only small parts and structures can be mounted on them. But for welding small parts, a rotary table has undeniable advantages.

An example of a simple but very convenient homemade welding table is shown in the video just above, and such a table is easy to make with your own hands from two old brake discs, a large ball and ordinary profile pipes.

The design of the control of pressing and fixing the table with a jack with a pedal under the foot allows you to free the welder’s hands during work, which is very convenient when using argon-arc welding, when both hands of the welder are occupied (one with a torch, and the other with a filler rod). But even when doing regular welding, such a table will be very convenient. The only thing that still needs to be improved is to drill a lot of holes in the table plate itself and thanks to this it will become much more convenient to attach various parts to the table using different ties, clamps, prisms, clamps, or clamps shown in the photo above.

Well, the clamps and welding clamps themselves are, of course, the most common welding devices, which are so simple that there is no point in describing them. They can also be purchased ready-made, or you can make them yourself, it all depends on the equipment of your workshop, which I hope will develop and be replenished with various tools over time. And not only welding fixtures, but also other useful tools, many of which are described on my website, in the “workshop, machines and equipment” section, good luck to everyone.

When performing welding work, it is necessary to securely fasten the parts to be welded together and conveniently position them. Some types of welding can only be carried out in a certain position, and the welding joint must be positioned accordingly.

Reliability of fastening is also important. During welding work, large stresses arise along the seam, which must be compensated for by the fastening equipment until the end of the process.

Various mechanisms and auxiliary parts are made at factories and at home. The simplest of them are easy to make with your own hands. In general, welding aids come in three types:

• mechanisms for installation, assembly, preliminary fixation;
• clamping devices;
• combined devices.

The first type of fixture is used to install parts in the position required for welding. Clamping welding fixtures firmly fix them and prevent them from slipping or turning. Combination devices perform both functions.

The choice of devices is related to the work conditions. It also depends on the requirements for the accuracy of manufacturing workpieces, requirements for clearances, and the design as a whole.

There are certain requirements for auxiliary devices. They must ensure free movement of the parts being welded caused by heating in the welding zone.

If large-sized products are welded, it is necessary to ensure fastening only at the welding points. The welder must be provided with free access to the welding site. It is also necessary to ensure rapid removal of the generated heat.

Cooking devices can be special or universal. For example, a special stand for assembling and welding frame products is a table with clamps.

Universal stands look the same, only they have additional devices for fastening the product, and due to this they can fix a large range of workpieces.

Fasteners

Clamps include devices that ensure a stable position of the welded product. They are made in the form of pockets, stops, mounting pins, prisms and templates.

Removable stops are used in universal stands when it is necessary to adjust for a specific product, or it is impossible to remove the product without deforming it.

Fingers allow you to accurately position the workpiece; they are usually used when working with products that have machined planes. Prisms are used when welding various pipes.

Templates are a design that follows the contour of the product being welded. The parts are installed in a template, welded, and the result is identical products when the welding process is repeated. The part itself becomes the load-bearing element, and the template sets the shape.

When making a single product, sometimes fixation is required in a non-standard way. It also happens that the necessary equipment is not at hand.

In this case, the welder makes it himself from scrap materials. To make homemade welding fixtures, a few pieces of corners and a pair of clamps are enough.

With their help you can get a simple and reliable lock. If you need to get a clamp for a connection at a right angle, just weld the corners perpendicular to each other and grab them with a third corner.

By welding the clamps in the right places, a clamp is obtained for perpendicular connection of products. That is, if necessary, the welder can provide himself with the required devices.

Clamps and tightening devices

Clamping devices play an important role. They press workpieces to clamps or tooling planes, and are mechanical, pneumatic and magnetic.

Mechanical clamps are very simple in design, therefore they are the most common. They are reliable, rarely fail and are inexpensive. Mechanical devices are wedge, screw and spring. Wedge clamps are usually used when aligning the edges of a product, when pressing the contacting parts of the parts being welded.

But the most common and universal devices are screw clamps, they are also called clamps. They are used mostly for single production and in the household, and require a lot of installation time. Spring clamps are used when welding small and thin workpieces.

Pneumatic devices can be used as welding aids. They have high performance, are distinguished by accuracy and a “death grip”.

Since compressed air is elastic, the device provides gentle compensation for deformations occurring during welding. Pneumatic systems are used mainly in mass production with a high level of mechanization. Hydraulic clamping systems are used to grip and press heavy parts (1 ton or more).

Magnetic clamps (also called holders) are easy to use, quickly installed and removed. They are used to align edges and press flat products to the base of the stand through a flux pad. In enterprises, electromagnetic clamps are most widely used, while permanent magnets are popular in private use.

The tightening devices include all kinds of ties, spacers and jacks. They have a wide variety of devices, sometimes quite complex designs, and are used to tighten and expand workpieces during the welding process.

Mechanized stands

When welding, a lot of time is spent on preparatory work. In these conditions, the role of mechanization devices is no less important than welding itself. Often it is completely irreplaceable.

The use of stands, racks and plates allows workpieces to be firmly secured. The product is pre-assembled and then fixed on the stand in the required position. Stands are often used when welding large, flat parts that are fixed with electromagnets or other clamps.

Rotators

To rotate large structures, so-called tilters are used. They come in roller and lantern types, lever, center and chain.

Roller devices are used to rotate large cylindrical structures. They are useful in the production of circular joints; they have several rollers: one is driven, the rest are used without a drive.

To prevent slipping, the drive roller is secured with a rubber band. Appropriate mechanisms are used for turning conical parts. They have several pairs of rollers located at an angle to each other.

Lever tilters are used when turning flat parts. Centering devices are used when it is necessary to rotate the product 360 °. Chain devices are used when welding large parts of long length.

Manipulators

These devices are adapted to rotate the welded product during operation. The manipulator can rotate the part in the vertical and horizontal plane, tilt it at different angles in the horizontal plane, which ensures a high-quality weld.

There are installation and welding manipulators. The first type of devices, also called positioners, installs the workpiece at the desired point and in the required position, convenient for assembly. move products along a given trajectory at the speed required for welding.

The main characteristics of manipulators are its load capacity, the maximum possible dimensions and the number of degrees of freedom of its faceplate, to which the part to be welded is attached.

In production facilities for welding work, there is usually a whole range of devices that ensure the installation of workpieces in the desired position, capable of moving them vertically and horizontally, and rotating them.

Additionally, rail tracks, trolleys and other devices are used to speed up and facilitate the welding process. Using standard, proven tools, the welding process is much faster and more efficient, although the use of homemade products never harms this.

To weld metal structures, experienced craftsmen often resort to the use of additional devices. They are called differently: accessories for the welding process, gadgets for welding equipment, devices for welding, etc. But the essence remains the same - all these tools serve to speed up and simplify welding.

We have devoted several articles to the topic of welding fixtures. For your convenience, we have collected them in one material, where we will give a brief overview of each of the articles. You will learn what welding supplies and accessories are used to join, apply current, and align parts.

There are a wide variety of welding accessories for joining two parts at a certain angle. The most primitive accessory is a metal square. It allows you to correctly position the parts, but does not fix them in a given position, which is not always convenient. Therefore, instead of a simple square, it is recommended to use corner clamps.

Corner devices for fixing and joining parts can be very diverse, despite their simple design. Manufacturers use a variety of metals to make corner clamps. And the longevity of using such a device largely depends on their correct choice.

In this article you will learn what corner clamps are, how to choose them correctly and use them in your work. We will tell you what nuances should be taken into account when working with an angle clamp so that the welding quality is at a decent level.

Welding equipment is unthinkable without a high-quality and reliable ground clamp, they are also pliers, they are also terminals. The use of a welding machine is impossible without clamping pliers. After all, with their help, an electrical circuit is formed by installing a tong on the part being welded.

The welding machine always comes with ground clamps, but they often require replacement. In this article we tell you in detail how to choose high-quality pliers and not make a mistake. You will learn what types of clamps there are and how to properly use such devices for welding with your own hands. If you are just starting to learn the basics of welding, then this article will be useful for understanding the essence of welding work. Because we explain in detail what a mass is and why a clamp is needed for it.

Another item that welding equipment cannot do without. The welding holder (holder, electrode holder) is used to fix the electrode during welding and supply current to it. Beginners often hold electrodes in their hands instead of purchasing a quality holder. And this is a big mistake. After all, with the help of a holder you can make a seam more accurately and evenly. And the device itself is not that expensive, but it is extremely convenient to use.

For any experienced craftsman it will not be difficult to choose a holder, but for a beginner, a large assortment can become a problem. There are many varieties, and even more manufacturers. And it is not clear which device is better. In this article we tell you what types of welding holders exist, which one you should choose and how to use it in your work.

Assembly fixtures for welding are the most important assistants of any master involved in welding metal structures. With their help, you can correctly join parts and form an accurate seam. At the same time, spending only a couple of minutes on all the preparatory procedures. We have already talked about one of these devices above, this is an angle clamp. But in addition to it, you can use a corner magnet for welding. It also fixes parts and allows you to weld them at a given angle.

Of course, you can use simple homemade clamps. But they will not provide the same quality of work as when using magnets. In addition, magnetic clamps are very precise and compact. They fit in your pocket and don't take up much space on your welding table. To use it, simply apply it to the parts to be welded. No need to use physical force or turn screws.

In this article we tell you how switchable magnets differ from regular ones, how to choose them and use them in welding.

Instead of a conclusion

In your work, sooner or later you may need welding devices for welding pipes, complex metal structures or small products for which accuracy is important. Welding tools make your work easier and faster. Thanks to them, the quality of welds improves, while you spend half as much time on welding work.

When an inexperienced welder comes to a store, he can simply get confused in a wide variety of fixtures, and the seller will take advantage of this and sell him an unnecessary or low-quality product. To avoid this, you need to study all the information regarding welding components. This way you will be confident in your purchase. Which of the devices listed above have you used or are using in your practice? Tell us about it in the comments below. We wish you good luck in your work!
