Electric welding, a familiar vocabulary, but we know that electric welding is in the end why can be welded out? What is the mystery and principle? Maybe we do not know that electric welding machine is also a kind of hardware and mechanical and electrical products! So today we briefly introduce the classification of electric welding machine!

Electric welding machine is actually a transformer with external characteristics, which can change 220V and 380V alternating current into low voltage direct current. Arc will be ignited during electric welding operation, and then the welding rod will be integrated into the objects to be welded at high temperature. Generally, there are two kinds of electric welding machines according to the type of output power supply, one is a direct current electric welding machine, and the other is an AC power welding machine.

Welding machine classification so far there is no a very authoritative method to classify, but we can use it from the industry to carry out a rough classification, the following list of five types of welding machine.

1. Industrial and mining enterprises: DC welding machine, AC arc welding machine, flash butt welding machine, pressure welding machine, argon arc welding machine, butt welding machine, spot welding machine, submerged arc welding machine, high frequency seam welding machine, carbon dioxide protection welding machine, AC welding machine and DC welding machine, touch welding machine, laser welding machine.

2. Gas shielded welding: one is carbon dioxide shielded welding, then the other is relatively rare, and the name is rarely heard by everyone. It is argon arc welding. Both welding machines have obvious advantages over other welding machines, because with gas protection during electric welding, there is generally no oxidation during welding, and solution welding is very firm, welding work can also be carried out on non-ferrous metals and relatively thin materials.

3. DC welding machine: This kind of welding machine can be divided into two types. One is to install some rectifier components on the basis of AC motor, and the other is DC generator. DC welding machine is mainly for everyone's common pig iron and non-ferrous metals such as welding work. AC welding machine is mainly for steel plate welding operation.

4. Submerged arc welding machine generally appears in the construction team, because its main welding objects are relatively thick steel materials such as girders, bridges and other steel structures.

5. Carbon dioxide shielded welding machine and argon arc welding machine are mainly used to weld thin plates below 2MM, and will produce color gold layer. Flash butt welding machine This kind of welding machine is mainly aimed at connecting joints and other objects made of materials such as copper and aluminum. If high-frequency butt welding machine is used, it is mainly suitable for welding steel pipes in pipe factories, which are generally not used by ordinary people.

When carrying out electric welding operations, be sure to wear electric welding machine auxiliary appliances, such as glasses to prevent infrared rays, ultraviolet rays and other rays from damaging eyes, as well as masks to protect the face and neck, foot guards, gloves and white overalls.
