The quality of laser cladding coating is determined by various process parameters and their interactions. Shape control of cladding coating can be realized by optimizing process parameters. In this paper, from the perspective of traditional optimization methods and intelligent optimization methods, the research status of cladding coating quality optimization at home and abroad was described in detail, the advantages and disadvantages of various optimization methods were summarized and discussed, and the role of different optimization methods in improving coating performance was analyzed. Finally, the future development trend of coating quality optimization method was prospected. The purpose of this paper is to provide an optimization method for the preparation of high quality cladding coating and to provide a reference for the future research of laser cladding process optimization method.
