英文摘要	Dissimilar metals of 1060 aluminum and T2 copper were joined with butt joint by pulsed double electrode gas metal arc welding-brazing. ER1100, ER5356, ER4043 and ER4047 filler wires were used as filler materials, respectively. The effects of composition of filler wires on the mechanical properties, the thickness of intermetallic compound layer and microstructure of joints were studied. The results show that the four welding joints are composed of fusion zone of the aluminum side, the weld zone, brazing zone of the copper side, and brazing zone was divided into two parts, namely, Al-Cu eutectic zone and Al-Cu intermetallic compounds layer zone. Si element in the filler wires is able to discourage the diffusion of Al and Cu atoms, which controls the growth of intermetallic compounds between Al and Cu as well as increase the microhardness and tensile strength of weld seam. While the addition of Mg has no obvious effect. © 2017, Materials Review Magazine. All right reserved.
