Dear all.
I have question for the EFW pipes.
I think EFW(electric fusion welded) pipes are made by GTAW, SAW, SMAW.., etc. welding process(with filler metal).
1. Is it possible to make EFW pipe with no additional filler metal?
2. in this case, is this ERW?
3. In case of stainless steel pipes, is the meaning of ERW/EFW dirrerent?
It would be highly appreciated if someone explain in detail.
