Magnetic pulse welding (MPW) is a solid-state welding method in which the magnetic forces are used to weld sheets together. The main aim of this paper is to investigate the welding quality of magnetic pulse welded Al/Al and Cu/Cu joints as well as the effect of back-plate support on them. The microstructural examinations by optical and scanning electron microscopes showed that a good bonding is obtained between the sheets welded by the high-velocity impact collision. Depending on the type of back-plate support, the welding interfaces were in either the planar or the wavy form. The microhardness test on the interface exhibited that the back-plate support is much more effective for thinner sheets of metals. It was also observed that the hardening due to collision is more profound in Cu/Cu joints when compared with Al/Al joints.
