Homemade magnetic corner for welding. Do-it-yourself magnetic angles or welding magnets. Magnetic corner manufacturing process

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 it's not in the corner large gap, 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 wide profile pipe, spread a strip of emery cloth on it, and manually ground down the sides of my metal triangles on it, periodically putting them into fitter's square and checking against the 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 be 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 to the planes metal plates, 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 using blind rivets. I will only use aluminum parts.

Small metal objects difficult to keep 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 come in handy home handyman, and a 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.

Types of magnetic holders for welding

A magnetic square is a mechanism for clamping one part or joining two parts, providing support in a given position during welding. It is suitable for a single procedure and serial production. The devices differ in design and operating features. There are the following welding magnets:

standard square with non-switchable magnet and stationary angles;

clamp – flexible device with the ability to adjust angles, suitable for products of varying complexity;

holders with different capacities - used to hold workpieces with different characteristics: for small ones - low power, for large ones - high power;

switchable models - after switching off, the holders detach themselves, the element is released without effort;

universal angles – equipped with several angles with frequently used parameters for performing complex and simple work;

three-coordinate and quadrangular devices - suitable for welding in difficult high-temperature conditions, they use ferrite magnets that can withstand temperature changes and cylinders.

For home use You can assemble a magnetic corner for welding with your own hands. Tool handicraft withstands mechanical loads. It can fix large parts, permanently hold and join parts of products to obtain high-quality seams.

Angular: permanent

Corner models consist of two plates with a magnet placed between them. These are multi-position devices with an adjustable clamping angle within 30⁰-135⁰. They are suitable for quickly fixing elements to be welded. The plates allow you to hold the object in one of 6 positions. Such mechanisms are acquired when, during the welding process, the workpiece needs to be rotated from several angles.

Important! Devices with fixed angles should be selected in situations where welding is carried out in frequently used positions

Disabled

Switchable models are devices with a magnetic field that is switched off with a special rotary lever. They make it easier to clamp and release the item being welded. Such devices are easily cleaned of metal shavings and small items.

Main selection criteria

For professional work should choose a tool High Quality. 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.

Homemade magnetic corner

Home craftsmen will be able to assemble a magnetic corner for welding with their own hands. To make it, you do not need highly specialized knowledge. You must first prepare:

magnet - thickness less than 15 mm;

steel sheet thickness 2-3 mm;

bolts M6 with a set of nuts or rivets;

heat resistant glue.

Important! The magnet configuration does not matter. Practice shows that it is better to choose it round shape. An option from a powerful speaker is suitable

The sheet of steel is marked in the shape of a triangle for subsequent cutting of the elements of the magnetic corner for welding with your own hands; it is better to take ready-made drawings. Use a grinder to cut out the first element according to the markings. The second part can be marked along the first by attaching it to the steel sheet. Using a file, clean the cut surfaces to a perfectly smooth state. Ready elements must be the same, no errors are allowed.

The triangles are applied to each other and clamped so that the edges completely coincide. They are fixed in a vice. Holes of the same diameter are drilled in the corners as bolts or rivets that will fasten the elements together.

A magnet is placed between the triangular plates. Its size should not exceed the parameters of triangles. The surface is pre-coated with glue. The parts of the holder are fastened with bolts or rivets. Painting with heat-resistant enamel is carried out after the glue has hardened.

Important! Your homemade tool with neodymium magnets is capable of holding workpieces weighing over 3 kg. It is recommended to periodically monitor the condition of non-heat-resistant analogues, so it is advisable to fasten their parts with bolts

When making a do-it-yourself magnetic angle for welding, you should take into account the features of the upcoming work. For welding in conditions high temperature Heat-resistant ferrite magnets must be provided. They do not need state monitoring.

Overheating of a mechanism not intended for heating leads to a decrease in its magnetic effect and irreversible failure. In non-removable structures it cannot be replaced.

For getting quality product As a result of welding, having only experience, professionalism and dexterity is not enough. It is also important to have all the necessary (welding equipment, etc.), as well as auxiliary tools for the job. They allow you to simplify and speed up the welding process, and it will be of higher quality and accuracy. Any professional should know how to do their job better using such auxiliary tools. One of them is magnetic corners. They can also be called welding magnets, a welding square, or a magnetic do-it-yourself welding square.

These tools are designed to fix metal parts and during welding process, soldering and assembly of products. Experienced master, without a doubt, will find application for this useful detail in other areas of the economy.

Magnets for welding: advantages of use

Used when working with round and round pipes rectangular shape, sheets of metal, non-standard shaped parts.
The welding angle can be of standard sizes, for example, 30, 45, 60, 90, 135 degrees. Also, a magnetic corner for welding can be universal and be adjusted to any required angle.
Operational fastening: magnetic holder for welding, it is fixed on the part independently.
The ability to work without the help of a partner, that is, labor costs are reduced to a minimum. This factor is especially important if there is a large volume to be completed. welding work.
Angles can be used in any location of the parts to be welded and at any angle.
Magnetic holders can also be used to mark any elements.

Nowadays for everything more For welders, magnetic angles have moved from the category of auxiliary tools to the category of necessary ones.

What types of fixing angles are divided into?

Division into types can occur according to various reasons. According to the source of their occurrence, they can be divided into factory corners and homemade ones. Of course, for professional use better buy corners famous manufacturers. For one-time uses on the farm, it is better to use a homemade magnetic holder, which is much cheaper.

You can make a magnetic square for welding from steel by first drawing drawings. The plates can be hand poured or cut using laser cutting. There should be a spacer between the plates that prevents the sticking of metal filings and gives the product more rigidity. It can be made, for example, from plywood. To collect all the elements together we use aluminum rivets and glue. As a result, we get a magnet for welding with our own hands. If everything is done correctly, it will be similar to the factory counterparts.

Magnets are also divided into types depending on the configuration and principle of operation:

The conventional holder design allows for a fixed angle setting.
The magnetic clamp is characterized by the ability to adjust any angle, which allows it to be used for work of any complexity.
The clamp can have a permanent and switchable magnet for welding. The last view is automatically switched off after welding is completed. That is, you don’t need to make any effort to remove it.
Most modern clamps have multiple angle settings, making them applicable to a wider range of welding applications.
Corners come in different capacities. To fix bulky, large and heavy parts, you need to use more powerful magnets, and light elements are welded using low-power magnets.

Thus, the importance of using magnetic corners for fixing products is very high. They simplify the work and allow you to do it more quickly, without the help of a partner. There are many manufacturers of magnets in different price ranges. It is important that the simple design allows you to make a magnetic square with your own hands, thereby minimizing material and labor costs during the work process. All of the above facts only speak about positive qualities this support material.

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 a 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 large production costs.

Magnetic corner manufacturing process

To begin with, 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 cutter on a machine, we create a hole equal to the inner diameter of the 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 make something unique measuring tool, which means the accuracy of the work must be at its best.

At the 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.

These tools are designed to hold metal parts and pipes during the welding process, soldering and assembling products. An experienced craftsman will no doubt find use for this useful part in other areas of the economy.

How to assemble a magnetic corner for welding with your own hands? : 1 comment

Your site is useful, a lot of interesting and useful information. Thank you for your work.

When welding small metal parts, it can be difficult to keep them stationary. To fix the elements in this case, the welder most often has to resort to the use of additional mechanisms and devices so that the parts do not move during welding.

The use of vices and clamps allows them to cope with this task perfectly, but the main disadvantage of such products is the need to carry out a large number of additional movements to install the part in a static position. And also the inability to fix parts at a certain angle.

A magnetic holder for welding does not have such disadvantages, so if you often have to weld parts in this way, it is recommended to purchase or make this device yourself.

Types of magnetic holders for welding

When performing welding work, magnetic devices of the following designs are most often used.

Angular: permanent

The advantage of this model of angles is the ability to quickly fix the parts to be welded in 6 positions. The device consists of 2 plates with a powerful magnet located between them.

If you often have to weld parts at different angles, it is recommended to purchase an adjustable holder.

A design with fixed angles will be much cheaper, but such a device should be purchased when the main part of the welding work involves fixing elements in the most frequently used position.

Disabled

The switchable magnetic welding holder is a device in which the magnetic field can be neutralized using a rotating lever.

Such devices cost several times more than a regular angle, but thanks to the shut-off function, using the product is easier and more comfortable.

Also, switchable models can be easily cleaned of metal shavings and other small parts.

Watch an interesting video where a person talks about a homemade switchable magnet for welding:

Which type of welding holder to choose depends on many circumstances. If the corner is needed for frequent use, it is recommended to purchase a switchable model with a tearing force of at least 20 kg.

Main selection criteria

If a magnetic holder is needed for professional use, then it is difficult for a beginner to understand the models on the market.

Below are the main criteria for selecting such a device, taking into account many factors.

Purchasing a low-quality product will complicate welding operations. high level. The holders are exposed to high temperatures, which can lead to a significant decrease in the magnetization coefficient of poor products. When purchasing, you should inspect the product for mechanical damage. Even a small recess or unevenness of the tool at the point of contact with the fixed elements will not allow the work to be performed at the required angle.
If you often have to weld parts at different angles, it is recommended to purchase an adjustable holder or a set of several triangles.
Not the last selection criterion is the price. The cost of many Chinese-made models can be very attractive, but often such devices fail after the first use.

To purchase a high-quality magnetic holder, it is recommended to consider products made in Russia and Europe.

Homemade magnetic corner

If you don’t want or have the opportunity to purchase a fixing device in a store, you can make it yourself from scrap materials.

A magnetic holder for welding with your own hands can be made using the following materials:

magnet from a powerful speaker;
steel sheet 2.5 mm thick;
heat-resistant glue for metal;
rivets.

To carry out the work you will need the following tools:

A homemade magnetic holder for welding work is made in the following sequence:

A triangular blank is marked on a metal sheet using a square and some sharp object.
Using a grinder, the workpiece is cut strictly along the intended stripes.
The cut blank is applied to metal sheet and the sheet is marked again.
An exact copy of the previous part is cut out.
Both triangles are filed with a file so that their side planes are perfectly even and the parts are absolutely identical.
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.
A magnet from the speaker is placed between the two triangles, onto the plane of which glue is first applied.
The square is placed in such a way that the holes of the plates are aligned and they are fixed together with rivets.
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 as magnetic material from hard drive computer. In this case, you can get a free and high-quality device with increased power.

During production homemade design the use of glue and rivets is the best option. If you apply 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 skills in self-production, then the instructions provided will help you make magnetic device with your own hands.
