英文摘要	The dissimilar metals of 5052 aluminum alloy/galvanized steel were joined with lap joint by pulsed double electrode gas metal arc welding-brazing with ER4043 filler metal. The interfacial microstructures of the joints were analyzed by scanning electron microscopy, energy dispersive spectroscopy and X-ray diffractometry. The results show that a zinc-rich zone locates at the weld toe, which is mainly composed of Al-Zn solid solution at the weld seam side and Fe2Al5Zn0.4 at the galvanized steel side. Si element in weld seam involves in metallurgy reaction of intermetallic compound formation and the Al8Fe2Si ternary phase is found, the phase Al8Fe2Si forms along FeAl3 side. The results of linear scanning indicate that Si atom obviously aggregates in the intermetallic compound layers. Further, the formation process of Fe-Al-Si ternary intermetallic compound was discussed on the basis of the test results. ©, 2015, Zhongguo Youse Jinshu Xuebao/Chinese Journal of Nonferrous Metals.
