Abstract
This paper elucidates the surface analysis of laser polished SS316L samples fabricated using wire arc additive manufacturing (WAAM). The fabricated WAAM samples were polished using Nd: YAG laser source of wavelength 1064 nm at different power and the various number of passes such viz. 10 W, 10 W, and 25 W, and 8, 10, and 15, respectively. The roughness measurement was performed on before and after laser polishing by an optical profilometer and found that 40% of roughness was reduced after laser polishing. The crystal phase changes and hardness were also carried out and validated using XRD and hardness of the laser polished samples.
