Abstract
The welding parameters, like laser power and welding velocity, influence the local solidification velocity and temperature gradient during welding. Thereby they determine the solidified grain structure. A numerical model is utilized to identify the influence of laser power and welding velocity on the solidified weld grain structure.The welding parameters, like laser power and welding velocity, influence the local solidification velocity and temperature gradient during welding.
