Abstract
The Nd:YAG laser welding is an advanced process for sheet metal welding. Inconel 625 alloy sheet is widely used in aircraft structure. The present paper is experimentally investigated about the Nd:YAG laser welding of Inconel 625 alloy sheet with improvement of geometrical accuracy and hardness of the welding area. The experiments carried out by using Box-Behnken design approach to predict the effect of Nd:YAG laser welding quality based on the welding parameters on laser power, welding speed, and frequency. In that, Box-Behnken design was used based on response surface methodology model, which is used on Design-Expert Software. The relationship between experimental value and RSM model is compared. Finally, based on the results, the proposed response surface models minimized welding bead width and hardness of the welding area for Nd:YAG laser welding of Inconel 625 alloy sheet.
