Black 32" EN10219 J0H Electric Resistance Welded Pipe

Electric resistance welding (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescenceoverlapping surface of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding. Some factors influencing heat or welding temperatures are the proportions of the workpieces, the metal coating or the lack of coating, the electrode materials, electrode geometry, electrode pressing force, electrical current and length of welding time. Small pools of molten metal are formed at the point of most electrical resistance (the connecting or “faying” surfaces) as an electrical current (100–100,000 Apasses through the metalas an electric current(100-100,000A), is passed through the metal. In general, resistance welding methods are efficient and cause little pollution, but their applications are limited to relatively thin materials
