从根本上阐明了ADC12与SS400采用搅拌摩擦进行焊接的可能性。对主要工艺参数，如转速、杆的旋转方向和销钉周边距材料界面的偏移量分别进行了优化。焊接只能顺时针方向进行，而不是逆时针方向。由于棒材本身的断裂，焊接过程中转速数字过大而失效。给出了引脚周边偏离界面的最佳条件，无论是在界面上还是在硬质材料内部。因此，在中等条件下进行焊接时，焊接接头的抗拉强度高于母材。在焊接接头界面区域未发现明显的金属间化合物相。提出了顺时针方向搅拌摩擦焊接铝合金与钢的焊接机理。
The possibility of a welding between ADC12 and SS400 by means of friction stirring was fundamentally clarified. The primary process parameters, such as a rotating speed, rotating direction of rod and offset of pin periphery from materials interface were optimized, respectively. The welding was performed only in the clockwise rotating direction while that was not in the counter clockwise. Too large figures of the rotating speed failed in the welding due to the broken of rod itself. Optimum condition in the offset of pin periphery from the interface was given as it is on the interface or inside of the hard material. Consequently, the welded joints showed higher tensile strength than that of the base aluminum material when the welding was pursued under the moderate conditions. Intermetallic compound phase was not detected obviously at the interface region of the welded joint. Welding mechanism between aluminum alloy and steel by means of friction stirring with clockwise rotating direction was proposed.
