In order to investigate interfacial morphology and their welding condition dependency, Al/Al and Cu/Cu lap joints were fabricated by magnetic pulse welding under various discharge energies. A part of flyer plate along the longitudinal direction of the coil bulged toward a parent plate and hit the parent plate. Two parallel seam-welded areas were formed along the side edges of coil, but the area between them was left unwelded. The welding interface exhibited characteristic wavy morphology, which was similar to that of explosive welding. Wavelength and amplitude of the interfacial wave were not uniform, but gradually changed through the interface. In addition, the maximum wavelength and amplitude increased with increasing discharge energy. Both macro-and microscopic features of interfacial morphology are considered to be due to the oblique collision behavior between the plates, in which traveling velocity, collision angle and collision pressure of the plates gradually change during the welding for a few microseconds.

“…In explosive welding, the collision speed can be adjusted according to the amount of explosives set before the welding process with the collision speed is approximately several hundreds to 1000 m/s or more (collision pressure is 10 GPa and above), making it possible to perform large surface area joining for various metal sheets. 17) On the other hand, MPW is also an impact welding which uses electromagnetic force, but at smaller scale as compared to explosive welding and produces a weaker seam welded materials.…”

Lap joint sheets of 2017-T3/2017-T3 and 2024-T3/2024-T3 were fabricated by magnetic pulse welding (MPW). Tensile shear tests were performed on the welded sheet, and a good lap joint was achieved at a discharge energy more than 3.0 kJ for both lap joint sheets. Weld interface showed wavy morphology when bonding at an adequate amount of discharge energy. Weld width of the lap joint sheets tend to increase with increasing of discharge energy. Collision speed calculated based on collision time was 211 m/s and estimated 1.5 GPa of the collision pressure at discharge energy of 3.5 kJ. SEM and EDS results showed that the weld interface exhibited no signi cant contrast of intermediate layer and oxides. A Metal jet was observed as aggregates of ne particles with size of less than 100 nm at the outside of bonded area. From TEM observation at the bonding interface, Al phases between yer and parent sheets had direct contact without the intervention of the oxide, and localized melting was not recognized. From these obtained results, good lap joint is attributed to true-contact of Al phases, an increasing of weld width, the anchor effect, and work hardening at weld interface.
