Electric resistance welded (ERW) pipe is manufactured by cold-forming a sheet of steel into a cylindrical shape.Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.Initially this manufacturing process used low frequency A.C. current to heat the edges.

Fusion welding is a generic term for welding processes that rely on melting to join materials of similar compositions and melting points. Due to the high-temperature phase transitions inherent to these processes, a heat-affected zone is created in the material 755 (although some techniques, like beam welding, often minimize this effect by introducing comparatively little heat into the workpiece).
