Abstract	Explosive welding using underwater shock wave has been conducted. This technique is a new method of explosive welding and can weld a steel plate with an amorphous film, multi-layer of thin copper plates and so on. The conventional method of usual explosive welding cannot weld these combinations of material. It is possible to change shock pressure acting on the flyer plate easily, because the equipment for this method can change the inclined angle and distance between the explosive and flyer plate. However, we have to understand the mechanism of this method to seek the most suitable for set-up condition. Therefore, the numerical simulation of this method was made. The simulation method was FDM using Lagrangean scheme and it can express the detonation process of explosive, propagation process of underwater shock wave, deformation process of metal plate and collision process of between flyer and base plates. In this paper, these simulation results are discussed.
