Magnetic corners for welding

Magnetic corners for welding - Metalworker's Handbook

Welding work requires maximum precision. It is convenient to secure structural elements in a certain position using a magnetic welding square. Manufacturers make magnetic fixtures for welders of various designs. They come with permanent and switchable magnets and differ in the load they can withstand.

Magnetic corners for welding

For welding work, magnetic holders with a certain size of corners are used. They produce universal designs with regulators; they secure the support bars to any angle. For home welding, craftsmen make their own compact squares from scrap materials.

Purpose of magnetic squares

1. The preparatory work takes a lot of time, the workpieces being welded must form a joint, to achieve this, sometimes you have to call an assistant to attach a clamp. With a magnetic welder's square, the procedure is simplified.
2. The quality of the seam and the geometry of precise structures depend on the fixation of metal parts in a static position. In this case, you have to use clamps; their installation is an obligatory part of the technological process.

   With a square, you can securely fix metal parts together without any tools.

3. It is difficult to mark metal when working at heights or in confined spaces. Making markings using corners is much easier.
4. With magnetic devices, the welding process is accelerated, labor costs are reduced, this is the economic component of using the angle.
5. The devices are easy to use: just lean them against the metal, they won’t move.

   They are securely fastened in any conditions, in a vertical, horizontal, inclined plane. Often used for horseback riding: elements secured with a magnet do not need to be held with your hands, they are protected from falling.

6. When using squares between the parts of the structure to be welded, the welder gains freedom of action, and there is no need to tack the parts before surfacing the main weld.

When using angles between the parts of the structure to be welded, the welder gets freedom of action

Types of magnetic holders for welding

Holders are classified by functionality, angle size, power.

Universal magnetic welding devices with sliding bars allow you to mate parts at any angle; they are suitable for complex work that requires high precision.

There are devices with several filler angles: 45°, 60°, 90°, 135°; during operation, you can set any one. Simple designs with a single filler angle allow the parts to be welded to be installed only in a certain position.

Universal magnetic corner with several adjustable mates

Magnetic welding holders have different powers, depending on the holding force of the magnet, with a maximum weight of 35 kg. The switchable corner is classified by type:

when both sides immediately stop being magnetic;

when the clamp has separate magnet switches for each side.

Switchable magnetic corner

How to choose a magnetic corner

First, determine the purposes for which the holder is purchased. If you need it for home welding, it is better to purchase a simple monolithic magnetic corner for welding, with one angle of mating parts. Its cost ranges from 500 rubles.

For permanent welding work, choose universal models with several adjustable mates, which have three or four edges. They come in various shapes and sizes, their cost depends on the holding power of the magnet, reaching 1000 rubles.

The clamps are made from heat-resistant alloys; they last a long time and are convenient to use.

It is important to pay attention to the quality of materials, because the corner is located in the heating zone of the metal, and due to the high temperature, the holding force of the magnet weakens.

Professionals choose holders with an adjustable angle between the slats. The advantages of such a tool are that a magnetic clamp is capable of tightly fixing rolled pipe in any plane.

The holding device is selected based on the weight of the parts and the complexity of the connection, so workshops purchase several simple and universal holders at once. When purchasing them, they check how quickly and easily it comes off the metal.

When choosing switchable latches, choose devices made of chrome; they are reliable and can withstand heavy weight. They are suitable for riding work, parts of the structure are held securely, you can loosen your hands when working. The cost of devices with switchable strips reaches 2 thousand rubles.

The corner should be easy to attach, securely fixed to the metal, and quickly removed. Only in this case will the device be used frequently. The corner will ensure safe work for the welder and will facilitate the process of precise mating of parts.

Magnetic corner and other welding accessories

Magnetic angles for welding help to fix and install all the required elements on them in the required position. Using a magnetic square makes it possible to save effort and time when working with a welding tool. In addition, the use of a square makes it possible to improve the quality of fastening of workpieces and workpieces.

Welding accessories

Today, there are a very large number of various devices and devices that help facilitate welding work . A special place among these devices is occupied by magnetic welding devices. Their design makes it possible to securely fix the parts to be connected using magnetic attraction.

The most popular among them are magnetic devices for corner welding (the so-called magnetic angles). There are a huge variety of these devices today, and they differ from each other not only in shape, but also in the presence of auxiliary devices (elements) in their design, which help simplify the fastening of different workpieces to each other. In addition, some individual magnetic angles make it possible to change the fixation angle.

During work, magnetic welding angles make it possible to attach such parts to each other as:

• sheet parts;
• frame structures;
• metal stands.

This capability is due to their versatility in the design of the square. If the use of an angle does not make it possible to make the required fastening, then it is used simultaneously with other fasteners.

Among these devices, we can highlight separately the Mag Tab holder , which has two support planes in its design. These planes can change the angle of their position; in addition, they have magnets installed in them, which simplify their attachment to the base.

The clamp is also equipped with two fastening planes, making it possible to fix the parts being processed. They are at an angle of 90 degrees relative to each other and have a low degree of freedom, which allows you to make the necessary adjustments before starting welding.

These magnetic holders have a fairly high attractive force , this makes it possible to create increased adhesive force and static stability of the material being processed during welding.

Other devices for welding

Although a magnetic welding square allows you to simplify the work procedure, at the same time there are also simpler welding devices. These include special clamps and clamps, and their price is much lower. In addition, you can build these clamps on your own, taking into account your personal needs.

These devices can last much longer than magnetized ones , since the presence of elevated temperatures during welding leads to a decrease in the magnetic field. That is, the longer you use the magnetic corner, the weaker it begins to magnetize parts.

Also among the devices that facilitate the welding process are gas lenses. These lenses make it possible to stabilize the gas flow rate during argon arc welding, creating protection for the gas. Gas protection occurs by regulating air access, preventing air leaks and the appearance of excessive turbulence in the gas flow.

These lenses are equipped with a fine mesh mesh that ensures an even flow of gas. The lenses are attached instead of standard collet clamps, and the torch nozzle must also be replaced. As a rule, gas lenses are used for welding titanium or other non-ferrous metals.

However, such a device also has its certain disadvantages . Among the disadvantages are the following:

• Increased gas consumption and reduced viewing angle (visibility) during welding work. Visibility is reduced due to the large diameter of the nozzle, which can create poor welding of the fasteners.
• When welding work with non-ferrous metals, certain working conditions must be observed. For which you will need one more device - a metal casing. The metal casing is also popularly called “boot”; it has the function of additional protection. The boot protects parts adjacent to the welding area from melting.

Such protection is even more relevant during the processing of titanium alloys. This is explained by the fact that if the operating temperature rises above 420 degrees , then molten titanium begins to react with gases. This reaction leads to a decrease in strength indicators and the formation of high brittleness of the metal.

For high-quality operation of the protective casing, its design must be in accordance with the geometry of the element being processed and the characteristics of the burner used. Quite often the casing is made by hand.

Aprons for welding work

In addition to protective covers, elastic aprons can also be used. These devices are used for processing cylindrical parts, since their design makes it possible to bend round shapes. Protective aprons are made from copper foil or thin sheets of copper.

Clamps for welding work

To make the apron more convenient to use, it is used simultaneously with clamps. Clamps help secure the parts being connected to each other.

This is especially true when, after careful and lengthy adjustment of two parts, they diverge even with a slight touch of the electrode.

But this situation can be complicated by the fact that separated elements can be connected to each other, and this will be revealed only after the seam has cooled . The use of clamps helps prevent such situations from occurring and will not lead to further correction of the work.

If welding is used in large-scale production of some parts, then it is more advisable to use special mechanisms that make it possible to easily turn over and conveniently stack workpieces. These devices make it possible to automate the entire work process.

Naturally, to install them at home, they are quite cumbersome and very expensive .

For individual use, devices are most often used that not only make welding work easier, but also facilitate the assembly of all parts and assemblies of the parts being processed.

These devices are divided into two main types:

• installation;
• securing.

Fastening mechanisms make it possible to perform a strong fastening using various clamps.

Installation devices make it possible to place the part in the desired position. These mechanisms include templates, stops and prisms.

But there are also universal mechanisms that combine both securing and installation functions.

Using stops, fastening is done on the main surfaces. The stops can be of a removable or throw-out design and are made of steel plates and bars, which are fixed with bolts. Squares make it possible to rotate parts at a certain angle of 30-90 degrees. Universal mechanisms are considered the most convenient to use. Using them, parts are connected to each other and tightened with bolts. Precise adjustment of parts can be done using eccentrics .

Thus, all these devices allow one person to weld, because the assembly and fixation of elements occurs not during welding, but before it. They can also be used to secure elements during cutting to prevent structural elements from falling.
