Abstract
AZ31B magnesium alloy plate was welded by YAG laser/TIG arc hybrid welding. Deep penetration with narrow weld bead was obtained by hybrid welding process compared to the TIG arc welding. To estimate mechanical property of hybrid welding for magnesium alloy, tensile test was conducted with butt welded joint. By comparison of welded joint with base metal, it was confirmed that hybrid welded joint has sufficient tensile strength.
