In this paper, 5A06 aluminum alloy was filled with friction stir spot welding. Mechanical properties and metallographic tests were carried out on the welded joint. By observing the microstructure of the weld, the effects of different welding parameters on the mechanical properties and cross section formation of the filler friction stir spot welded joint were analyzed. The results show that the welding time has the greatest influence on the shear resistance and tensile properties of the friction spot welding joint, and the increase of the rotation speed of the spot welding tool will enhance the tensile properties of the joint.
