Laser-resistance hybrid welding is used to weld LF6 aluminum alloy plates and the process characteristics are analyzed. Thanks to the interaction between laser and resistance heat,the weld depth and cross section area increase evidently. The aluminium alloy joints with full penetration are achieved with low laser power,resulting in the welding efficiency increasing and production cost reducing. The amount of pore in hybrid welding joints decrease compared with that of laser welding. Microstructure observation indicates that the β(Al8Mg5) strengthen phase in weld zone is typical as-cast structure and dispersal distribution,and in heat-affected zone (HAZ) the β strengthen phase clusters grow up together. During tensile test,the hybrid welding joint ruptures at weld zone with ductile shear characteristic. The average tensile strength of hybrid welding joints is 292 MPa,about 83.4% of base metal.
