Stainless steel flange, in order to prevent intergranular corrosion caused by heating, the welding current should not be too large; at this time, the current should be about 20% less than that of carbon steel electrode, the arc should not be too long, the intermediate layer should be cooled quickly, and welding should be reduced. When welding stainless steel flange, repeated heating will cause carbide precipitation, thus reducing corrosion resistance and mechanical properties.

Stainless steel flange is easy to crack after welding. If the same type of stainless steel electrode is used for welding, it must be preheated to more than 300 ℃, and slowly cooled to about 700 ℃ after welding to avoid flange cracking. If the weldment can not be heat treated after welding, the appropriate stainless steel flange electrode should be selected. In order to improve corrosion resistance and weldability, stable elements such as titanium, niobium and molybdenum are added appropriately.
