Popular processes for welding stainless steels electric resistance welding pipe steels make it ideal for thin materials and root runs in one sided welding of thicker plate and pipe. The process is easily mechanised and the ability to weld with or without the addition of filler wire (autogenous welding) make it the process for orbital welding of pipe. electric resistance welding pipe steels Electric resistance electric resistance welding pipe steelsChina Electric Resistance Welded Steel Pipe factory and electric resistance welding pipe steelsElectric resistance welding (ERW) refers to a group of welding processes such as spot and seam welding that produce coalescence of faying surfaceswhere 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, Development of API X-80 grade electric resistance temperature with ultra low carbon steels to keep coarse hard secondary phase away to improve the toughness. On the other hand, by hot rolled sheet to ERW (electric resistance welding) pipe manufacturing process, X-80 line pipe steel with bainitic microstructure made by low stop-cooling temperature was also studied4). The ERW process can gain electric resistance welding pipe steels
