(1) Dimension measurement before repair; (2) Mechanical processing and cleaning of damaged parts; (3) Laser cladding repair: The alloy powder for laser cladding is Ni-Cr-Mo or Co-Cr-W alloy powder, laser fused The cladding equipment adopts high-power fiber-coupled semiconductor lasers, with a power of 1800～2500W, a spot diameter of 3～5mm, a cladding speed of 8～15mm/s, and an overlap between tracks of 40%～60%. (4) Finishing and non-destructive inspection after cladding: Lathe and grinder are used to process the parts after cladding to meet the size requirements, and penetrant inspection is used to ensure that the repaired parts are free of cracks and pores. WILA realizes the automation of the laser cladding process, the part deformation during the cladding process is small, there is no pollution, the cost is low, and the service life of such parts is significantly extended.
