Stainless steel electrode can be divided into chromium stainless steel electrode nickel and chromium stainless steel electrode, the two kinds of electrodes in every accords with national standard, all according to GB/T983-1995 evaluation provisions. Chromium stainless steel has certain corrosion resistant (oxidizing acid, organic acids, cavitation) heat resistant and corrosion resistant performance. Usually was chosen for power station, chemical, petroleum and other equipment materials. But chromium stainless steel usually solderability poorer, should pay attention to welding technology, heat treatment condition and the choice of appropriate welding wire. Nickel chrome stainless steel electrode has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, oil, medical machine manufacturing. To prevent the heating and produce between eye due to corrosion, welding current should not be too big, about 20% less than the carbon steel electrode, arc should not be too long, the fast cooling between layers, with narrow welds advisable.
