| Summary: | In this study, Inconel 625 powder was deposited on ASTM A592 steel substrate using laser cladding process. In order to optimize and predict the quality of the obtained coating, empirical-statistical method was used and the linear relationship between the coating geometries for each sample (angle, width, height, depth of penetration and dilution) and cladding parameters (power, powder feeding rate, and scanning rate) was obtained by the use of regression method. Using these relationships, a process map has been extracted to obtain the best quality for the cladding process. Hence, it is possible to obtain the optimal parameters of coating geometry and the main laser parameters for the deposition of Inconel 625 powder on the ASTM A592 steel substrate with minimum porosity and without crack.
