采用搅拌摩擦扩散工艺成功地实现了ADC 12与SS 400的焊接。实验是通过具有硬质合金工具的加工中心进行的，并且优化了焊接条件，诸如旋转速度、焊接速度和工具的位置。通过将旋转工具插入到具有偏移的界面中，以50 mm/min的焊接速度在高于2000 rpm的旋转速度下焊接ADC 12和SS 400。转速高于5000 rpm时，试样在焊缝区断裂，抗拉强度较低。另一方面，在2000和4000 rpm之间制造的试样在基础铝合金的部分中断裂。在本摩擦搅拌工艺中，接头效率达到100%以上。
Welding between ADC12 and SS400 was successfully performed by friction stir diffusion process. The experiments were conducted by a machining center with a cemented carbide tool and welding conditions, such as a rotating speed, welding speed and position of the tool, were optimized. By plunging the rotating tool into the interface with offset, ADC12 and SS400 were welded above 2000 rpm of the rotating speed at the welding speed of 50mm/min. Tensile strength was evaluated for the welded specimens. The specimens fabricated above 5000rpm in the rotating speed were fractured at the weld zone and showed relatively low tensile strength. The specimens, on the other hand, made between 2000 and 4000 rpm were fractured in the portion of the base aluminum alloy. Achievement of more than 100% in joint efficiency was indicated in the present friction stirring process.
