Abstract:Laser weld bonding (LWB) is a hybrid welding technology that combines laser welding and adhesive bonding. In the hybrid welding process, the adhesive significantly affects the welding process and the property of the LWB joint. Results show that the adhesive partially decomposes in the heat-affected zone, the impaired size of which is mainly attributed to laser beam power. The property of the LWB joint is influenced by the thermal impaired area and adhesive thickness. To control the adhesive thickness and reduce the weld porosities in the fusion zone, a metallic interlayer is added in the welding process of LWB. (C) 2014 Elsevier Ltd. All rights reserved.
