Experimental Study Based on the Widening Melting Roads Cladding Forming of the Hollow Laser

Abstract:

Our research group has invented a kind of new technology called coaxial inside-beam powder feeding. By series of experiments, this paper analyzed and summarized the process parameters’ influence on the cladding layers’ feature and quanlity, which contain the laser power P, the powder feeding speed V_f, the scanning speed V_s and the defocusing distance L. Some cladding experiments also were made to aquire the cladding roads with variable width. The experimental results indicate that when P, V_f and D×V_s are fixed, roads with stable height and uniformly changing width are acquired by changing V_s and L at the same time.
