ERW Electric Resistance Welding Tube Mill Pipe Mill

Electric Resistance Welded - an overview ScienceDirect

Preferential corrosion attack in the weld area, leading to premature leaking, was observed in electric resistance welded (ERW) of carbon and low alloy steel pipes exposed to neutral salt-containing waters. The selective and localized corrosion prefers to occur in the weld, especially close to the fusion line.
