Welded Pipe Manufacturing Methods SAW, ERW, EFW &
ERW/EFW and HFW are welding methods in which pipe is welded without adding filler material. However, EFW welding method can be used with filler material also. ERW Pipe Manufacturing Process. In ERW welding, two electrodes, usually made from copper, are used to apply pressure and current.
Electric Resistance Welded an overview ScienceDirect
Feb 17, 2009 · When electric resistance welded carbon steel pipe was exposed to aggressive waters, grooves caused by the redistribution of sulfide inclusions along the weld line were formed in the weld. The material at the bond line is anodic to the surrounding material and the result is a V shaped groove with the apex of the V centered on the bond line.
