The optimization research of process parameters for big power Laser cladding oil distribution plate parts, is a research focus of modern surface hardening technology. The article discussed for solving the optimum pro-cess parameters of Laser cladding for the selection approach of strategy of genetic algorithm, the quantitative rela-tionship model was established between process parameters and the oil distribution plate parts property using neural network method , which process parameters are laser power (P), scanning speed (V), powder feeding r...
