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 commonall 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.Electric Resistance Welded Tubing | Industrial Tube and erw electric resistance welded pipeCold rolled electric welded (CREW) tube is produced per ASTM A513 Type 2.
