Metaheuristic Techniques-Based Optimizing Laser Welding Parameters for Copper-Aluminum Alloys

Abstract

In this research endeavor, the laser welding of C63000 alloy has been thoroughly examined, focusing on the interplay of key welding parameters—laser power, welding speed, and amplitude. The experimental design, structured as per the Taguchi L9 array, provided a systematic approach to investigating these parameters' effects on critical mechanical properties, specifically tensile strength and Brinell hardness. The alloy's responses were meticulously studied under varied conditions, capturing the nuances of its behavior in response to changes in laser welding inputs. The experimental outcomes revealed distinct trends in tensile strength and Brinell hardness in relation to the variations in welding parameters. Notably, the highest levels of tensile strength and hardness were consistently observed under specific combinations of welding speed, laser power, and amplitude.
