To carry out high-quality welding work, it is necessary to correctly carry out preparatory procedures. Takes a lot of time from the performer fixation process welded workpieces. Besides assembled structure may fall apart from contact with equipment or electrode. The welder will need to spend a lot of time and effort on restoration. To avoid such situations were created special magnetic accessories designed for fixing parts. Such compact devices allow you to avoid the help of colleagues and save time on creating additional accessories larger scale (for example, “third hand”).
What types of clamps are there for welding work?
There is enough a large number of additional devices for fixing workpieces. They are not mandatory items for a welder, but significantly make work easier And improve the quality of the resulting connection.
Important! It should be noted that the concept “magnet” can include various devices.
Square corners
Magnetic corners are the simplest type of product for fixing parts to be welded under required angle. Basics dignity such devices - reducing the time spent on preparatory procedures, as well as reducing the labor intensity of the process.
Holders have 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.

Why is it better to buy a set at once?
Manufacturers and suppliers sell welding magnets individually. Most welding work is carried out with 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
Mass holder(other names: ground terminal, ground clamp) is a necessary device for a welder. The ground terminal will eliminate the possibility of electric shock and will guarantee a reliable and quality connection. Industry provides ground contact devices various types : clothespin, magnetic clamp, clamp and centralizer. Let's look at the pros and cons of magnetic representatives of this type of equipment (see the entire article).
Regardless of the type, holders have the following important advantages: ease of use and speed of work. Also worth noting 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 by large area contact 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 workpieces small size: rod or reinforcement.
The advantages and disadvantages of other types are presented in the article.

Torch holders
The holder is support with 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.
The use of holders during storage is especially important gas burners, since their nozzles crack when they come into contact with a cold surface on which the equipment is placed.
Magnetic base guarantees structural stability, which can be located on welding table or can be attached to a working device.

Magnetic welding mirror
The welder's magnetic mirror is designed to for inspection and quality control welds , facilitates the implementation of work in hard to reach places. The magnet allows you to attach the mirror to any metal surface and don't hold it in your hands. Most models have 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.

Switchable and non-switchable devices
Magnetic welding holders can be permanent and switchable. The second type is attached to parts by turning on the activator magnetic field. Similar devices have the following dignity, in comparison with conventional magnets: quick withdrawal 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 more high price.

Dimensions
Magnetic attachments are different 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 force of gravity(holding or pressing) 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.
With your own hands
Some craftsmen like to create devices themselves rather than buy 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 metal sheet 2-3 mm thick; magnet; fasteners: screws and nuts.
Manufacturing algorithm:
1. On metal sheet Using a ruler and 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.
3. The magnet is fixed between the workpieces and assembly is performed.
4. For assembly, you need to drill holes: for a triangular shape - three, for a trapezoid - five. Using bolts and nuts you need to assemble the product. The nuts must be screwed not only onto the end of the bolt, but also between the metal plates to prevent the product from bending when screwing in the bolts.
5. Bolt tails extending beyond the nuts should be cut off.
Important! Non-magnetic bolts or nuts should be selected. If these are not available, then you can use aluminum or copper tubes as end caps. This will eliminate the possibility of contamination of the magnet and its demagnetization.
7. The magnetic corner is ready for use.

Torch holders
The torch holder has more complex design, so it will be necessary to put more effort into it self-made. The performer will need magnet, fasteners: non-magnetic bolt and nut, 3-4 mm metal sheet.
The holder support can be various shapes
. The welder can cut a workpiece, the template of which will be similar to industrial models, and also develop an individual shape. It all depends on the ability to use the grinder, the assigned tasks and the imagination of the welder.
- Sheet metal required cut the workpiece the desired configuration and sand it from the end and front sides.
- At a distance of 20-30 mm. from the bottom edge bend the workpiece at a right angle, then screw the product to the magnetic base.
- The tail of the bolt extending beyond the nut should be cut off.
- The device is ready for use.
Mass holders
The manufacturing process of the mass holder is simple. The welder will need a minimum of tools. Required Parts may be at hand. Detailed and understandable instructions for any master are presented in a separate section. The video will help you visually study the process.
Welding mirror
Focusing on the purchased one, a DIY craftsman will be able to make a homemade magnetic welder mirror
To make a magnetic mirror for welding, the contractor will not need to cut metal. A magnet, a brass bendable rod 400-500 mm long, and a mirror whose dimensions do not exceed 100 mm must be available. On the one side; fasteners; hinged holder.
Using a hinged holder, the mirror is attached to a flexible rod, which is then attached to a magnet using bolts and nuts.
Make or buy
Having become familiar with the process of making magnetic devices, each performer will be able to decide to create a product with their own hands or purchase a “ready-made” one. Option self-made Suitable for performers who like to make things on their own. In addition, it is not always possible to find the desired or desired model of device on sale. To perform some work, the welder needs a square of a non-standard shape to obtain the angle of the required size.
Professional welders prefer to buy ready product
, this saves time.

Hello to all DIY lovers!
Today I want to show you one of the options for making a simple magnetic corner (holder) for welding work. The idea is certainly not new, there are many modifications of this homemade product, but in terms of functionality they are practically no different, and you can get quite a lot of benefits from this thing, considering that when welding, you often have to work alone. Actually, this prompted me to make this holder. I will describe where it can be applied at the end of the article.
Necessary materials
To make a magnetic corner you will need:Two furniture corners
- three extended nuts
- six bolts
- half a magnet (it’s better to use neodymium, of course)
Manufacturing a welding angle
First of all, we shorten the bolts so that they can fit into the enlarged nut (select the sizes individually). I cut off the bolts with a regular grinder.
Next, I sanded the magnet a little to round off the sharp edges a little and so that it would fit in the corner between the nuts.
Then I slightly drilled holes in the corner for the bolts, and also drilled additional ones in the middle of the corner in order to secure it with three nuts in the future.
Now we need to put everything together.
To make the instrument look beautiful and stand out from other instruments, I painted it bright blue.
It all turned out quite beautiful!
Using the Welding Holder
Now the actual use of the magnetic corner in practice:Using this homemade product, you can easily and simply weld parts at an angle of 90 degrees alone, without holding the workpiece.
For example, below is the photo. On the first one, a piece of reinforcement was welded simply by hand:
As you can see, the workpiece was beveled and a right angle did not work out.
On next photo the same piece of reinforcement, but using a homemade magnetic holder:
As you can see, the result turned out much better!
In addition to this option, you can also use a magnetic holder when welding parts from the side or even from below, and you also don’t have to hold the workpiece. 
Of course, this holder is not suitable for any work where large and heavy workpieces are used, but for small household work it simply cannot be replaced. And if you need to secure something large, then you can simply make a larger holder with a neodymium magnet, which has a much higher attractive force. It all depends on your needs.
When carrying out welding work, moments arise when it is necessary to simultaneously grip a part and hold it at a certain angle. This work requires two people or special tool. The most commonly used is a clamp. With its help, the part is fixed in the desired position. However, the clamp has a lot of disadvantages. Therefore, you need a special magnetic holder that will help you do this work quickly and without unnecessary hassle.
Advantages of a magnetic corner for welding
- Capable of holding both metal parts, freeing your hands to do the main work.
- It does not block access to the connection point, which makes it better than a clamp.
- Allows you to create several angle options.
- Easy to use.
- Does not require high costs during manufacture.
Magnetic corner manufacturing process
First, we need a magnetic disk with a diameter of ~15 cm and an internal diameter of ~5 cm. We also need to have squares of sheet metal 3 mm thick, with a side of 20 cm. It is very important that the sides of the square are perfectly even. It is advisable that the thickness of the magnet does not exceed the material most used in the work. The best option is 1-1.5 cm.
Place the magnet in the center of the square and trace it with a marker to create a marking. Next, we apply cutting lines to the metal that need to be made to create the pattern.
We clamp the workpiece in a vice, and use a turbine to cut off the excess elements.
We apply the resulting part to the second square to outline its contours. Next, we also remove the excess from it with a turbine.
We connect the two resulting blanks together and secure them by welding. Now we can perform one operation on two parts at once.
Next we need two threaded couplings. We install a magnet on the workpiece, applying it to the previously designated location. Then we distribute the couplings along its perimeter, at the same distance from each other. We mark their position with a marker.
We remove the couplings. We mark holes in the center of the location of the couplings. Next, using a drill corresponding to the diameter of the hole in the coupling, we make holes in our workpiece. It is through them that the bolts for fixation will be installed.
After this, we weld a piece of pipe to the workpiece, the diameter of the internal hole of the magnet. We fix it exactly in this place. As a result, we got a part that can be clamped in a lathe chuck.
Using a drill and a cutter on a machine, we create a hole equal to internal diameter magnetic ring.
We remove the welded pipe and clean our part. In this case, it is very important to obtain perfectly smooth edges while maintaining compliance with the corners. Therefore, you will have to work not only grinder, but also with a file. We are making a kind of measuring instrument, which means that the accuracy of the work must be at its best.
On next stage we will need couplings and bolts for them.
The workpieces are separated and cleaned. Next, install a magnet and couplings on one of them.
Today I want to talk about a magnetic welding square that I recently made with my own hands. I will soon have to make several gates and entrance gate, so I decided to make some magnetic squares this winter. They will save me a lot of time and effort when welding rectangular structures from profile pipes.
What I needed for this:
1. Old speaker.
2. Sheet metal (steel) 1 millimeter thick
3. A strip of thin aluminum.
4. Blind rivets.
Progress of work on the manufacture of a homemade magnetic square
Using a hammer and chisel, I separated the "magnetic part" of the speaker. (It is secured with four rivets).
After this, all that remains is to remove the magnet.
Next I started making the plates. I cut them out of an old window sill. (I’m surprised myself, but it was made of “black” non-galvanized iron, 1 mm thick!). The metal was very magnetic, which was what I needed in the first place.
Using a mechanic's square, attaching it and the resulting magnet to the workpiece, I determined the dimensions of my future product, drew it and cut it out with a grinder:
Firstly, when cutting profile pipe(and especially the thick circle on cutting machine, burrs remain on the edge. When welding, they will melt easily and will not interfere. But the square will rest against them. Therefore, after the pipes are cut to size, you will have to clean off these burrs.
Secondly, if there is not a large gap in the corner, you can accidentally weld the square itself to the workpiece.
I did not mark the second plate. I simply attached the first one to it (already with cutouts) and, according to this template, marked it and cut it out too:
I took a piece of a wide profile pipe, spread a strip of emery cloth on it, and manually ground off the sides of my metal triangles on it, periodically putting them into a bench square and checking “for light.”
After that, folding the blanks evenly and squeezing them in a vice, I drilled holes in them for the rivets. (I forgot to photograph this process). And after that, just in case, I tightened them through the holes with M5 screws and once again “finished” them on sandpaper, this time two together.
Many DIYers make the angles “open”. That is, they don’t cover the end with anything! It is unacceptable. Because when working with metal, a lot of sawdust, scale, small scraps and other magnetic debris appear. Since all this debris is very light, it sticks abundantly to the magnet.
That is why its shape should be such that it can be easily cleaned!!! That is, its ends should represent smooth planes. I made them from a thin aluminum plate. Some kind of edging from an old refrigerator shelf came under my hand.
From it I cut a strip with a width equal to the thickness of the magnet:
And from it I bent a frame around the perimeter of the plates. It will be inserted between them, and tightly clamped with rivets.
A ferrite magnet can be cut quite easily with a grinder. But, unlike cutting metal, use abrasive wheel don't even try!!! It will slip and you will simply overheat the magnet. (By the way, if anyone doesn’t know, permanent magnets lose their properties due to overheating.). You need to cut with a diamond wheel. A diamond wheel for wet cutting is best suited.
And when cutting, the magnet must be cooled with water.
Why did I make the ends out of aluminum, and at the same time focus on another common mistake. As you know, any magnet has two poles, conventionally called “north” and “south”. Both poles are equally well attracted to the metal. Magnets of this shape have poles on planes. That is, when we apply metal plates to the planes, then these plates are the poles of the magnet. And it is with them that our square will “stick”, and not at all with the plane between them.
But, most importantly, the poles of the magnet cannot be “short-circuited” with magnetic material! This reduces its properties, and, in addition, contributes to the fact that the magnet, albeit slowly, demagnetizes!
I decided to connect the plates with blind rivets. I will only use aluminum parts.
Very often, in order to carry out high-quality welding work, experience alone is not enough. Even professionals use welding aids, such as magnetic welding angles, to help hold parts in place during work and prevent them from moving.
The main objective of this design is to ensure precise joining of two products, most often at an angle of 90 degrees. However, professional magnetic corners allow you to hold parts at any angle.
Advantages of a magnetic angle for welding
- Magnets for welding allow you to work not only with sheet metal, but also with products of complex shape.
- Thanks to the presence of a magnet welding work are greatly simplified.
- Quickly fix the product at the desired angle.
- Welding magnets allow you to work in any plane.
DIY magnetic square
Even an inexperienced craftsman can easily make a magnetic angle for welding with his own hands. For this you will need the following materials:
- Sheet metal 2-3 mm thick in section;
- Round magnet;
- Bulgarian;
- Screws, nuts.
Let's consider step by step production products:
- Before starting to manufacture the product, it is better to study the diagram of the magnetic square. Professionals recommend that beginners use monolithic products. Templates for such designs can easily be found on the Internet or created individually for yourself. We mark the future product on a metal sheet. It is important that the angles are as straight as possible.
- Using a grinder, we cut the workpieces and check their corners.
- We change cutting disc in a grinder for cleaning and carefully grinding the product. All corners of the two plates must match exactly. If something does not match, the corners are adjusted to maximum purity. In addition, both the end and front parts are polished so that rust and other defects do not reduce the strength of the magnetic field.
- We fix the magnet between the two plates and carry out the assembly.
- We drill out the fastening points and assemble the magnet for welding using screws and nuts. M6 type bolts are used for assembly. The nuts are screwed not only onto the end of the bolt, but also between the metal plates to prevent the product from bending when screwing in the threaded bolt. It is important that the round magnet does not protrude beyond the edges of the templates. The shanks of the bolts that extend onto the nuts must be cut with a grinder.
- Checking the distance between corners
- The magnetic corner for welding is ready.
When using both homemade corners and store-bought ones, do not forget about the operating temperature conditions. Thus, welding magnesium requires very low temperatures, other alloys require stronger heating, which can lead to loss magnetic properties corner.
