Electric welding is a well-known word, and electric welders are also the objects of frequent ridicule, such as fish scale welding, dragon scale welding, dragon whisker welding and so on. But do you know why electric welding can be made? What are the mysteries and principles? Maybe you don't know that electric welding machine is also one of the hardware and electromechanical products! So today we will briefly introduce the classification of electric welding machines!

The electric welding machine is actually a transformer with external characteristics, which can change 220V and 380V alternating current into low-voltage direct current. The electric arc will be ignited during the welding operation, and then the welding rod will be incorporated into the objects to be welded under high temperature. There are two kinds of electric welding machines according to the type of output power, one is DC electric welding machine, and the other is AC electric welding machine.

Up to now, there is no authoritative method to classify welding machines, but we can roughly classify them for industrial purposes. Here are five types of electric welding machines.

1. Industrial and mining enterprises: DC electric 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 welding machine, carbon dioxide protective 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, and the other is argon arc welding, which is rare and rarely heard by people. Both of these welding machines have an obvious advantage over other welding machines, because they are protected by gas during electric welding, and there is generally no oxidation during welding, and solution welding is very solid, It can also weld nonferrous metals and relatively thin materials.

3. DC welding machine: This electric welding machine can be divided into two types. One is to add some rectifier components on the basis of AC motor, and the other is DC generator. DC welding machine is mainly used for common pig iron and non-ferrous metal welding work. AC welding machine is mainly for electric welding of steel plate.

4. Submerged arc welding machines are also commonly used in construction teams, because their main welding objects are thick steel materials such as girders, bridges and other steel structures.

5. Carbon dioxide protection welding machine and argon arc welding machine are mainly used to weld the thin plates below 2MM, and will produce gold colored layer. The flash butt welding machine is mainly used to connect copper, aluminum and other materials such as joints. The high-frequency butt welding machine is mainly used to weld steel pipes in the pipe factory, which is usually not used by people.
