Stainless steel welding wire in gray cast iron welding process

Gray cast iron stainless steel welding wire has many welding methods， such as arc welding, gas welding, CO2 gas shielded arc welding and so on.Production process use welding process to repair defects. When cold welding accidentally, it will crack. When the preheat temperature of gray cast iron 600 ~ 700 ℃ welding. It will have a certain degree of plasticity, elongation up to 2% to 3%. Temperature difference is smaller weld and base metal
