英文摘要	A galvanized steel is used to join Mg AZ31B alloy and Al A6061-T6 alloy as a joining transition layer by cold metal transfer (CMT) method. Firstly, to optimize the process variables, extensive welding tests were performed by a design of experiment method. Then, microstructures, joining mechanisms and tensile properties were characterized and analyzed. Results indicated that Mg and Al alloys can be joined by using galvanized steel as a joining transition layer and cold metal transfer welding method. The formed joint is called as a Mg-steel-Al CMT joint. By using galvanized steel transition joining layer, Mg-Al brittle intermetallics Al12Mg17 and Al3Mg2 were inhibited. The properties of Mg-steel-Al CMT joints have been improved after optimizing the welding variables. The strength of Mg-steel-Al CMT joint is comparable to those of Al-Al joint and Mg-Mg joint. The strength of Mg-steel-Al CMT joint can reach 100% that of Al-Al joint and Al-steel joint, and reach 90% that of Mg-Mg joint and Mg-steel joint. The optimized Mg-steel-Al CMT welded joint with galvanized steel transition layer is fractured at the heat affected zone of Al base metal rather than at the weld-brazed interface, due to softening of Al base metal.
