This study aims to establish the weld quality of the Nd:YAG laser-MIG hybrid welding on galvanized steel (SGACC60). In order to do so, the Taguchi analysis optimized the laser-arc hybrid welding process for SGACC60 by varying four parameters: welding speed, welding current, laser-arc distance and shielding gas. The experiment produced 18 combinations of these four essential welding parameters, which were estimated in terms of ultimate tensile strength, welding depth and width ratio, and hardness. The optimum result exhibited that the tensile strength of welds was approximately 101% of that of the base metal, and that their hardness was within the acceptable range (the maximum value 350 Hv).
