Tensile-shear mechanical properties of friction stir spot weld bonding hybrid joint in welding prior to and after adhesive curing for vehicle using
This research proposed a temperature-controlled friction stir spot weld bonding process as a solution to the issues of adhesive carbonization and weld impurities in the traditional combination of friction stir spot welding and adhesive bonding. A comprehensive investigation was conducted, including the establishment of a simulation model using the DFLUX subroutine to analyze the welding temperature field and the implementation of an overflow groove to separate the weld from the adhesive. The microstructure and mechanical properties of the joint were examined in the joint of welding before and after the adhesive curing process. The results demonstrated significant improvements in the failure load of the hybrid joints, with increases of 57.4 % and 27.7 %, compared to the welding joint. Additionally, the failure mechanism of the hybrid joint was elucidated by analyzing the fracture morphology.
