Description: Pearlitic heat-resisting steel with coating of low sodium hydrogen electrode. DC reverse connection and all position welding. Workpiece shall be preheated about 150-250°C before welding and tempering at 620 710°C after welding process. |
||||||||
Application: WER107 Heat-resistant Steel Electrode apply to weld the covering of the boiler pipes (e.g.15Mo) after argon arc render with working temperature below 510°C. Can also apply to weld general high strength low alloy steel. |
