erw welding steel tubes 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.
