High-frequency electric resistance welding (ERW) steel pipe production, internal weld surface treatments are generally incomplete curettage (left weld reinforcement) and complete curettage (scraping will form the inner surface of the groove) in two ways, and the results were not ideal, will affect the overall performance of the steel pipe.
electrical resistance weld pipe Electric resistance welding - Wikipedia
Low-frequency electric resistance welding, LF-ERW, is an obsolete method of welding seams in oil and gas pipelines. It was phased out in the 1970s but as of 2015 some pipelines built with this method remained in service. Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape.
