Abstract
In this study, aluminum alloy A5052 and magnesium alloy AZ31 were joined by conventional parallel setup of explosive welding and underwater explosive welding. Microstructural characterization of conventional welded joints revealed a characteristic wave formation with vortices and contact surface melting layer containing intermetallics. In order to reduce the vortices and melting layer, underwater explosive welding was used. The welding parameters are regulated to reduce the kinetic energy loss during collision. The low kinetic energy loss in underwater explosive welding resulted in the formation of small waves with less vortices and no melting layer.
