Abstract The lap welding process of friction stir welding was used on 1.2 mm thick 6016-T4 aluminum alloy and 1.0 mm thick galvanized IF steel. Through the study of the mechanical properties and the interface microstructures of the joint, it was found that the joint formed well under the condition of the welding speed of 100 mm/min and the rotation speed was 800—2 000 r/min, and the surface had no groove, holes and other defects. When the rotation speed was 1 200 r/min, the shear strength of the joint reached 172 MPa, which was 82% for the strength of aluminum alloy. The hardness value of aluminum alloy was “W” type distribution and the lowest hardness of the aluminum alloy was at the junction of the thermo-mechanically affected zone and the heat-affected zone, the highest hardness in the weld nugget area was 69.1HV. The hardness value of galvanized IF steel was “U” type distribution and the highest hardness in the weld nugget area of the galvanized IF steel was 192.3HV; Under the influence of the pin and the shoulder, the interface of aluminum and steel lap joints presented the characteristics of mechanical connection and metallurgical connection; “Hook” structures were formed at the two sides of the pin zone, which was inserted into the aluminum alloy matrix to form a mechanical connection, Fe-Al intermetallic compounds, Al-Zn compounds and Fe-Al layers in the steel and aluminum interface form metallurgical connections.
