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.

Electric resistance welding at a glance - The FABRICATOR

Jun 13, 2002 · Several electric resistance welding (ERW) processes are available for tube and pipe production. While each process has different characteristics, all ERW processes have one thing in common–all of them produce a forged weld. A forged weld is created by applying a combination of heat and pressure, or forging force, to the weld zone.
