In this study these advantages of the laser welding has been considered for Nd:YAG laser stitch welding(LSW) as a substitute for resistance spot welding(RSW) of lightweight car body plates. First, optimized parameters for Nd:YAG laser stitch welding for automotive high strength steel sheet(SRPC340) have been determined comparing the economical and mechanical characteristics to match with the currently used spot welding characteristics. Second, the mechanical phenomena of thermal elasto-plastic behavior on the Nd:YAG laser stitch welded joints has been clarified by two-dimensional thermal elasto-plastic analysis using F.E.M.
