Welding Rod Used For Stainless Steel

Stainless steel electrodes can be divided into chromium stainless steel electrodes and chromium nickel stainless steel electrodes. Those two types of electrodes that meet the national standard are evaluated according to the national standard GB / T983-1995. Chromium stainless steel has certain corrosion resistance (oxidizing acid, organic acid, cavitation) heat resistance and corrosion resistance. Usually selected as equipment materials for power stations, chemicals, petroleum, etc. However, chromium stainless steel generally has poor weldability. Attention should be paid to the welding process, heat treatment conditions and selection of suitable welding electrodes. Chrome-nickel stainless steel electrodes have good corrosion resistance and oxidation resistance, and are widely used in chemical, fertilizer, petroleum and medical machinery manufacturing. In order to prevent the corrosion between the eyes due to heating, the welding current should not be too large, about 20% less than the carbon steel electrode, the arc should not be too long, the interlayer cooling is fast, and the narrow bead is suitable.
