Abstract: 1050 industrial pure aluminum and Q235 low carbon steel were welded by continuous drive friction welding. The tensile properties of the joints, room temperature impact strength and bending tests were analyzed and demonstrated. The morphology features and composition of IMCs were analyzed by SEM, EDS and XRD. The differences in heating power between different regions of the welding interface during welding led to the differences in the diffusion behavior of Fe and Al at the interface, which led to the differences in the morphology features of IMCs at the interface. The IMCs in central region of the interface are small-needle-shaped Fe3Al. The IMCs at a distance of 1/2R from the center are rod-shaped FeAl. The IMCs at a distance of 2/3R from the center are square-stick-shaped FeAl3. Fe3Al and FeAl in the interface have better ductility than other Al-rich IMCs.
