Petrosadid: Electric Resistance/ Fusion Welded (ERW and EFW)

High 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.
