As it is an improvement from the inherent problems of hardness, lack of fusion and susceptibility of stress corrosion cracking (SCC).
2 days ago · High frequency welding (HFW) is mainly used for ordinary or thin-walled steel pipes. It includes contact welding and induction welding. DC welding is usually used for small diameter steel pipes. Generally, HFW is one of ERW production methods, which uses high-frequency welding technology. Therefore, ERW steel pipe includes HFW steel pipe. Differences between ERW Steel Pipe and HFW Steel PipeHigh frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.
