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 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.differentce between ERW pipe and EFW pipeLike low frequency ERW pipe, the seams of flash welded pipe are prone to rust and hook cracks, but to a lower level than ERW pipeline. R= Resistance and F= Fusion hence you would have Electric Resistance Welded Pipeline or Electric Combination Welded Pipeline. The more typical are 0.85 for ER W pipeline and 0.60 for CW pipe.Welded vs. seamless steel pipe | American Piping ProductsAn advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. Thats opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application. Welded pipe manufacturing techniques have improved over the years.
