Laser cladding process for wind power sliding shaft

The invention belongs to the technical field of wind power sliding shaft machining, and particularly relates to a wind power sliding shaft laser cladding process which comprises the following steps: S1, removing surface defects of a workpiece; s2, the workpiece is cleaned, and the non-machining position of the workpiece is shielded; s3, a cladding track program is written according to process requirements; s4, process parameters are set, and a laser cladding mechanism is made to conduct laser cladding according to the cladding track program; and S5, after laser cladding is completed, shielding is removed, and the workpiece is machined into the finished product size. By adopting an infrared semiconductor laser cladding method, laser cladding copper alloy cladding and repairing remanufacturing of the sliding shaft in the wind power industry are achieved, a cladding layer is free of cracks, air holes, sand holes and other defects, a technological method of a copper lining is replaced, the copper lining and a pla
