Resistance butt welding is a method of continuously pressing the ends of two workpieces using contact heat to heat the contacting part to a ductile state, and then quickly applying top forging pressure or without adding top forging pressure to maintain only welding pressure to complete the weld.
Contact us1. Resistance butt welding is a method of continuously pressing the ends of two workpieces, using contact heat to heat the contacting part to a plastic state, and then quickly applying top forging pressure or without adding top forging pressure to maintain only welding pressure to complete the welding.
2.Compared with flash butt welding, flash butt welding is easy to operate, affordable, and has high welding efficiency.
3.After welding, the joint is smooth and the burrs are small.
4.It is mainly used for butt welding of metal profiles with cross-sectional area less than 250mm, such as iron wire, sheet material, pipes, etc.
