Lap joining of a pure aluminum plate and a low carbon steel plate was performed using friction stir spot welding. Welding was achieved for all dwell times. Intermetallic compound layer was produced along the welding interface. Precise backscattered electron image observation and energy dispersive X-ray spectroscopy analysis revealed that the intermetallic compound layer consisted of an Al_<13>Fe_4 phase layer and an Al_5Fe_2 phase layer. The thickness of the layers increased in proportion to the square root of the dwell time.

采用搅拌摩擦点焊技术对纯铝板和低碳钢进行搭接连接。焊接是在所有停留时间内实现的。沿焊接界面形成金属间化合物层。精确的背散射电子像观察和能谱分析表明，金属间化合物层由Al&lt；13&gt；Fe4相层和Al5Fe2相层组成。各层的厚度与停留时间的平方根成正比。
