Welding advantages of ERW carbon steel pipe:
Resistance welding of ERW carbon steel pipe is the way that the welding of workpiece is pressed between two electrodes and applied electric current to heat generated by thermal resistance flowing through the workpiece surface and adjacent areas so that it can reach the form of melting or plastics to make metal connection.

Advantages of ERW carbon steel pipe
1. The heating time is short and the heat is concentrated, so the heat affected area is small and the deformation and stress are small. It is unnecessary for ordinary people to adjust after welding and heat treatment.
2. The composition of gold block is surrounded by plastic ring, melting metal and air barrier, and the metallurgical process is simple.
3. There is no need for filler metal such as welding wire and electrode, as well as welding materials such as oxygen, acetylene and hydrogen, so the welding cost is low.
4. Resistance welding has high output, no noise and harmful gas. In the production of multiple rolls, other manufacturing processes can be compiled with the assembly line. But flash welding needs isolation because of spark splash.
5. Simple operation, easy to complete mechanization and initiative, improve the premise of labor force.
