electric resistance welded - an overview ScienceDirect ...

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.
