To solve the problems of low strength and unsatisfactory connection quality of single joining technology, a method of clinch-adhesive hybrid joining of steel/aluminum sheets with partially glued and inclined wall die was proposed. Al5052 aluminum alloy and Q235 steel were used as research objects, finite element simulation combined with actual experiments was adopted, the effect of the gluing process on the strength of clinch-adhesive hybrid joints on the inclined wall die was explored, and the failure forms and failure mechanisms of the joints in shear and peel experiments were studied. Results showed that the effect of partially glued is better than that of complete gluing. And the partial gluing process is more effective than the complete gluing process. The interlock of partially glued hybrid joints was increased by 144% compared to fully glued joints, but the neck thickness value was reduced by only 10.6%. The shear strength and peel strength of partially glued hybrid joints are higher than fully glued hybrid joints and clinch joints. The failure mode of the hybrid joints under shear and peel loads is mixed failure composed of interface failure and upper sheet separation failure.
