　　Whether the welding pipe thread?

　　Can, generally used for welding heat resistant steel, stainless steel and other metal materials. Welding in the special environment of the workpiece or structure, such as wear resistance, corrosion resistance, high temperature and low temperature with high mechanical properties should be selected to ensure electrode deposited metal properties and parent material similar or similar, this is principle of identity. Such as welding stainless steel, should use stainless steel welding rod; heat resistant steel should be selected with heat resistant steel electrode. Proportional control action.
