Recent studies have emphasized on the deployment of aluminium alloys (AA5083 and AA6061-T6) for automotive industry owing to their excellent corrosion resistance, mechanical properties, and low specific density. Standard welding techniques have been overshadowed by the difficulties associated with joining these alloys. In this research, we investigate the feasibility of fiber laser welding in joining similar and dissimilar AA5083 and AA6061-T6 alloys. The laser power and welding speed were varied to determine the optimum condition to produce a viable welding joint. The properties of the joint such as hardness, and tensile strength were examined. It was found that both macro-voids and solidification cracks occurred in the weldment zone when high welding power (310 W) and high welding speed (24 mm / s.) were used. The presences of micro porosity were inevitable at the optimum welding condition. The study also found that the dissimilar welding of the alloys exhibited improved mechanical properties, this was associated to a refined microstructure and controlled porosity in the weldment.
