· Electric resistance welding at a glance

· Features of SSAW steel pipe production process

· HFW steel pipe defects in production

· the difference between ERW, SSAW, LSAW

· Our technical support for ERW steel pipe , SSAW steel pipe & LSAW stel pipe

· Features of SSAW steel pipe production process

· Ultrasonic Test System for SSAW Pipe Weld Seam

HIGH-FREQUENCY WELDING is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating.

Coil edges are milled using carbide cutters in order to assure a high quality weld. Coils are then formed by cold forming method using a set of cage rolls and fin passes, and then joined using high frequency currents using induction or alternatively conduction methods.
