Laser Welding of Aluminum to Copper: Properties of The Welded Joints and Optimization of Parameters

Laser welding is a procedure wherein materials are fused together using a beam of high-energy intensity generated through the concentration of light waves. Laser welding has gained significant prominence in the industrial manufacturing sector in recent years due to its various advantages. These advantages include high welding speed, low heat input, narrow weld seams, rapid cooling resulting in minimal heat-affected zones, suitability for automation, successful joining of different materials, and the ability to weld materials of varying thicknesses. In this study, the Taguchi Method was employed to determine the optimal parameters with minimal experimental effort. Mechanical properties, particularly tensile strength, were analyzed using the Minitab software based on the welded joints produced. Detailed examinations were conducted based on predetermined variables for the welding process.
