Abstract
Hybrid welding combined YAG laser welding process and TIG arc welding process was developed for thin plate welding. It was applied to welding of 2mm thickness SUS304 stainless steel plate and AZ31B magnesium alloy plate. In consequence, sound penetration bead of stainless steel was obtained by hybrid welding process. In case of magnesium alloy hybrid welding, improvement of heat efficiency was remarkable. Moreover, tensile test results of hybrid weld joint shows sufficient joint strength of magnesium alloy.
