- Abstract
In this paper, the dissimilar resistance spot welding of A6061 aluminum alloy and AZ31 magnesium alloy sheet is studied, and the middle layer is Zn and Sn. The results show that the addition of Zn and Sn as the intermediate layer can effectively prevent the formation of intermetallic compounds, and can enhance the quality of the joint. It is found that with the increase of welding current, the tensile shear load of the welded joint increases first and then begins to decrease. Mg-Al compound formation was not observed at the interface of the joint. The results show that the addition of the middle layer hinders the direct contact between aluminum and magnesium, inhibits the interface reaction and improves the performance of the joint.
