In ERW process, the strip for tube making is continuously edge sheared and rolled into tube for ...
Electric resistance welding at a glance
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.ASTM A53 ERW Steel Pipe Inspection Process - Industry TodayAug 18, 2020· The details of A53 ERW pipe evaluation process: 1.
