Lighter and more resistant to corrosion compared to other metal alloy, using Aluminum alloy leads to lower energy consumption and more sustainable vehicle for automotive industry where the 5052-H32 Aluminum alloy is present in several parts. But welding Aluminum alloy remains a real issue because of its high thermal conductivity, low melting point and high reflexivity. However, innovating technique such as double-sided laser beam welding is a solution to get over those difficulties by compensating the laser energy loss by two times laser beam crossing. Double-sided laser welding provides deeper weld seam with low heat distortion as revealed by micrographic analysis. Parameters optimization results in the best ultimate tensile strength (UTS) for the welded parts by reaching the optimum value of parameters which are the laser power and the welding speed, obtained from complete factorial design (CFD) and analysis of variance (ANOVA).
