| Abstract: | Laser cladding rapid prototyping technology commonly uses round, rectangular or linear spot for making cladding powder melting and rapid solidification. Coupling stability of spots and pink spots is relatively poor. The thesis makes research on the ring laser cladding process and the impact of process parameters on the microstructure of the molded parts and made analysis of the relationship between the different process parameters and the cladding layer quality for a reasonable choice of experimental process parameters. |
