Welding machines are electrical appliances that provide power with certain characteristics for welding. Welding is widely used in various industrial fields, such as aerospace, shipbuilding, automobiles, and containers, due to its advantages of flexibility, simplicity, convenience, strength and reliability, and the fact that the welded material can even have the same strength as the base material.
What are the different types of welding machines?
There is no authoritative classification method for welding machines. Based on Baidu Encyclopedia and industry experts' summaries, welding machines on the market can be simply divided into the following categories according to their uses:
1. The main welding machines used in industrial and mining enterprises include: DC welding machines, AC arc welding machines, CO2 shielded welding machines, spot welding machines, submerged arc welding machines, high-frequency welding machines, argon arc welding machines, flash butt welding machines, pressure welding machines, spot welding machines, butt welding machines, and laser welding machines.
2. There are two types of DC welding machines: one is based on an AC motor with a rectifier added, and the other is a DC generator. DC welding machines are mainly used for welding non-ferrous metals and pig iron. AC welding machines are mainly used for welding steel plates.
3. Argon arc welding machine, carbon dioxide shielded welding machine, high frequency seam welding machine, flash butt welding machine. Argon arc welding machines and carbon dioxide shielded welding machines are mainly used for welding thin plates less than 2mm thick and non-ferrous metal layers. Flash butt welding machines are mainly used for butt welding copper and aluminum joints, etc. High frequency seam welding machines are mainly used in pipe manufacturing plants for welding steel pipes.
4. Submerged arc welding is mainly used for welding thick steel structural materials such as steel structural components, bridge H-beams, and I-beam beams.
5. Gas shielded welding: Carbon dioxide shielded welding and argon arc welding. Under the protection of gas, the welding will not oxidize, the weld is strong, and it can weld non-ferrous metals and thin materials.
6. Laser welding machine: can weld the internal leads of transistors.
7. Welding machine: Mainly used in chain factories to weld iron cables and other objects on anchors. Can also weld round steel bars, etc.
8. Multi-functional electric welding machine.
9. Spot welding machine.
10. Butt welding machine.
11. Bolt welding machine.
12. Carbon dioxide ammonia gas welding machine.
