A  Welding Wires with corrosion (oxidation acid, organic acids, cavitation), heat and abrasion resistance. Typically used in power plants, chemical, oil and other equipment and materials. Chromium stainless steel welding poor, should pay attention to the welding process, heat treatment conditions and selection of suitable welding.
 2, chrome 13 stainless steel welding, hardening of large, prone to crack. The use of the same type of chromium stainless steel electrode (G202, G207) welding must be carried out more than 300 ℃ preheat and post weld about 700 ℃, the slow cooling treatment. Weldment can not weld heat treatment, you should make use of chrome-nickel stainless steel electrode (A107, A207).
 3 17 stainless steel, chrome, to improve corrosion resistance and weldability appropriate increase in the amount of stability of the elements Ti, Nb, Mo, weldability compared with 13 chromium stainless steel. Using the same type of chromium stainless steel electrode (G302, G307), should be above 200 ℃ preheat and post weld tempering around 800 ℃. Weldment can not be heat treated, you should make use of chrome-nickel stainless steel electrode (A107, A207).
 4, chrome-nickel stainless steel electrode has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical machinery manufacturing.
 5, chrome-nickel stainless steel welded carbide precipitation by repeated heating and reduce the corrosion resistance and mechanical properties.
 6, drug skin of chrome-nickel Mig Welding Electrode with titanium calcium type and low-hydrogen type. Titanium calcium type can be used for AC-DC, AC welding penetration is shallow, and easy to redness, so as far as possible with DC power supply. Diameter of 4.0 and below can be used for all position welding of 5.0 and above for flat butt and fillet weld.
 7, the electrode should be used to keep dry, lime-titania type shall be dried at 150 ℃ 1 hour, low-hydrogen type shall be 200 ~ 250 ℃ dry 1 hour (can not be repeated drying, otherwise the drug leather easy to crack and peel off) to prevent the electrode drug skin sticky oil and other dirt, so as to avoid causing the weld to increase the carbon content and impact of welding quality.
 8, in order to prevent corrosion between the eyes, the welding current is not too large, about 20 percent less than the carbon steel electrode, the arc should not be too long, rapid cooling between layers, in order to narrow weld heating is appropriate.
 Dissimilar steels should be careful selection of welding rod, to prevent improper electrode selection of hot cracking or high temperature heat treatment caused by the σ phase precipitation, metal embrittlement. With reference to stainless steel and dissimilar steel welding rod selection criteria for selection, and take appropriate welding process.
