The welding process of the lap joint between a 5182 aluminum alloy and a DP1180 two-phase steel sheet (1.2 mm thick) is deeply studied by friction stir welding, defects not revealed, and high-quality welded joints were obtained. The steel plate pressed to 0.2 mm is placed under the aluminum plate. With a large-size friction stir head, the rotational speed was 800 rpm and the welding speed was 50 mm/min, respectively. Many steel particles flaking in the aluminum matrix were distributed in the vicinity of the interface of the weld zone; they were surrounded by a thick layer of an intermetallic compound. This continuous and uniform layer composed of Al4Fe (EDS analysis) was formed at the interface.
