• •The FSEW-B process was used for the first time for welding of AA5083 to Cu using pure Zn as interlayer.•The shoulder geometry noticeably affects the materials flow and weld strength.•The fracture load of joints is determined by the filling of pre-threaded hole and the width of brazed zone. Friction spot extrusion welding-brazing of pure copper to 5083 aluminum alloy sheet using pure Zn as interlayer has been elucidated. The effect of shoulder geometry on the microstructural characterizations and mechanical behavior of the joints was explored. Results indicated that changing the geometry of the shoulder from cylindrical to triangular not only enlarged the brazed zone from 14.98 μm to 19.65 μm, but also the tensile/shear strength had a rising trend and improved from 3268 N to 4398 N, which can be attributed to the larger brazed zone and complete filling of the pre-threaded hole in the joint produced by the triangular shoulder.
