Electric resistance welded (ERW), spiral submerged arc welded pipe (SSAW) and longitudinal submerged arc welded pipe are three different forms of welded steel pipes (LSAW). The three welded steel pipes are manufactured in very different ways. WebDuring the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond. Meanwhile with the combined pressure, the edge of the pipe billet steel melted and extruded together. ... caretaker led light
