研究了锻铝与镀锌钢的冷金属过渡 (CMT) 焊接产生的界面微观结构和金属间化合物。结果表明，反应层主要由 FeAl3 相组成，由于 CMT 方法的热输入较低，反应层厚度降低至 7~8 μm。较薄的反应层保证了接头的拉伸性能。最后根据异种金属接头的界面特性，详细描述了界面反应过程。
The interfacial microstructures and intermetallic compounds produced by cold metal transfer (CMT) welding of wrought aluminium to zinc coated steel have been investigated. The results showed that the reaction layer mainly consists of FeAl3 phase and the thickness of the layer was decreased to 7–8 μm owing to the low heat input of the CMT method. And the thin reaction layer guarantees the tensile property of the joint. At last, according to the interface characteristic of the dissimilar metal joint, the interfacial reaction process was described in detail.
