ERW is Electric Resistance welding,ERW pipe and submerged arc welding pipe welding method is significantly different, The pressure welding method without filler metal is adopted, and no other components are filled in the welding seam. By the skin effect and proximity effect of high-frequency current, the plate edge is instantly heated to the welding temperature, and the weld with forged structure is formed by extrusion roller. High quality steel pipe requires weld line or off-line heat treatment to refine the weld zone. The weld line of high quality ERW welded pipe can reach the same toughness level as the base metal, which cannot be achieved by submerged arc welding process
