Abstract: The IPG-500 laser was used to implement laser cladding on 45# steel. The influence of process parameters on the morphology of the cladding layer was studied, and the key factors affecting the morphology of the cladding layer were obtained by range analysis. On this basis, the gray correlation degree was used to analyze the correlation between the quality of the cladding layer and the ideal cladding layer quality under different parameter combinations, and the optimal combination of laser cladding process parameters can be found. The results show that the laser power and scanning speed are the main factors affecting the morphology of the cladding layer, and the optimized cladding layer is obtained under the conditions of laser power of 400W, scanning speed of 7mm/s and powder feeding rate of 0.7r/min, which provides theoretical support for the selection of laser cladding process parameters.

Key words: remanufacturing, laser cladding, range analysis, parameter optimization, grey relational degree
