Abstract

Aluminum alloy 6061 was welded with zinc coated low carbon steel by cold metal transfer (CMT). The microstructure composition, morphology and growth process of the welding joint and the HAZ were researched. The weld area on the side of the galvanized steel sheet mainly contains Fe2Al5. And on the side of the aluminum alloy substrate, it is mainly filled with a needle-like FeAl3. At the same time, Al8Fe2Si is formed at the edge of FeAl3. The zinc-rich region on the side of the aluminum alloy mainly contains an aluminum-zinc solid solution and an aluminum-zinc co-crystal, and the current size had no significant effect on the type and morphology of the compounds produced in the interface layer.
