摘要：Dissimilar metal joining between 5A02 aluminum alloy and H62 brass sheets was conducted by gas tungsten arc welding with Zn-15%Al and Al-12%Si flux-cored filler wires. The microstructure in the weld and distribution of major alloying elements in the interfacial layer were examined, and the tensile strength of the resultant joints was measured. Pores appeared in the weld made with Zn-15%Al flux-cored filler wire, the interfacial layer mainly consisted of AlCu phase, and the specimens fractured through the weld with tensile strength of 129 MPa. When Al-12%Si flux-cored filler wire was used, Cu diffused into the weld and Al2Cu phase formed, and the specimens fractured along the interfacial layer with tensile strength of 122 MPa. ? 2013 Editorial Board of CHINA WELDING.
