Rotor shaft has a small pit solution: 1. Use an angle grinder to grind the gouging cleaning part and the edge of the defect until the metal luster is exposed, and the welding repair can be carried out after confirming that there are no defects. 2. Welding repair. The transition layer welding current is about 90A, short arc welding, small current, fast welding, narrow weld bead, electrode does not swing, reduce heat and heat affected zone width, improve weld intergranular corrosion resistance and reduce the tendency of hot cracking. 3,. Cleaning and inspection after welding. After welding, remove the coating, slag, weld bead, etc.
