摘要：Dissimilar Mg alloy and Q235 steel lap joints are produced by Laser- tungsten inert gas (TIG) hybrid welding with Ni as an inter-layer. Fe and Ni are joined together in the form of solid solution, while Mg alloy and Ni foil are joined together by intermetallic compound Mg(2)Ni. During tensile testing, the joints fail at the interface between Ni foil and Mg alloy. The shear strength of the Mg/Steel joints with Ni as interlayer is 170 MPa, which is higher than that without interlayer 120MPa.
