    Differences Between Electric Resistance Welding and

    ERW is the abbreviation of electric resistance welding. The welding method of ERW pipe and submerged arc welded pipe is significantly different. The pressure welding method without filler metal is adopted. The weld is not filled with other components, and the skin effect and the proximity effect of the high frequency current are used to instantaneously heat the edge of the plate. Differences Between Electric Resistance Welding and Jan 10, 2020 · High-quality steel pipes require heat treatment on the weld line or off-line to refine the microstructure of the weld zone. The weld of the high-quality ERW welded pipe can reach the same level of toughness as the base metal, which cannot be achieved by the submerged arc welding process. EFW is the abbreviation of electric fusion welding.
