Abstract

The joining of magnesium alloy AZ31B and mild steel Q235 is realized by the addition of a Ni interlayer using resistance spot welding technique. The bonding mechanisms of the dissimilar joining have been investigated using mechanical testing and metallurgical examination. The results show that the formation of intermetallic compound (Mg2Ni) and solid solution of Ni in Fe at the interface plays an important role in the bonding of Mg alloy and steel at the centre of the nugget zone, which contributes to the increase of the tensile shear strength of joints. Besides, Mg alloy and Ni interlayer are joined by Mg2Ni intermetallic compound layer at the edge of the nugget zone, but steel and Ni interlayer only form a mechanical bonding.
