This paper presents the results of recent investigations on laser seam weld bonding (LWB) of magnesium alloy AZ61 sheets. There are two types of LWB structures: perpendicular weld seam (LWB-PE) and parallel weld seam (LWB-PA). In this paper the differences between the two structures are compared and discussed. In tensile shear tests, both LWB-PE and LWB-PA joints can offer higher failure force than that of laser welding or adhesive bonding alone, and LWB-PA joint offers better performance than LWB-PE joint. This is because the weld seam can increase the peel resistance at the free end of the adhesive bonded part, where a stress concentration exists. Maximum T-Peel strengths of LWB joints depend on the laser seam weld. The LWB-PA joint has both the advantages of maximum failure force caused by laser weld and the peel displacement caused by adhesive, so a synergistic effect is obtained in energy absorption.
