Welding Advantages of erw carbon steel pipe

Welding advantages of erw carbon steel pipe:
Resistance welding of erw carbon steel pipe is the welding of the workpiece will be pressed between the two electrodes, and the application of current, the application of current flow through the workpiece surface and the adjacent area of the thermal resistance generated by heating it to the molten or plastic form, so that metal connection of a way. 

The advantages of erw carbon steel pipe
1, Heating time is short, heat concentration, so the heat affected area is small, deformation and stress is also small, mortals do not have to adjust after welding and heat treatment process.
2, Nugget composition, has been surrounded by plastic ring, melting metal and air barrier, metallurgical process is simple.
3, Do not need welding wire, electrode and other filler metal, and oxygen, acetylene, hydrogen and other welding materials, welding costs low.
4, Resistance welding yield high, and no noise and harmful gases, in the production of multi-volume, and other manufacturing processes can be compiled together with the assembly line. But flash welding due to spark splash, the need for isolation.
5, Simple operation, easy to complete mechanization and initiative, to improve the labor premise.
