Abstract
A new method of explosive welding is proposed. In the new method, an explosive put on block of the thick steel in set on the one side of the specimen. The whole set-up is submerged in the water. When the explosive is detonated, underwater shock wave moves on the flyer plate from the near side to explosive to the far side. The shock wave holed a very high pressure, so that the flyer plate is abruptly accelerated by pressure action and collides with a suitable velocity to the parent plate a slightly apart from the flyer plate. Thus explosive welding is achieved. Shock pressure decays with the distance from the explosive. To make up the energy loss of shock wave, a reflector of thick plate is covered the passage of shock wave. To obtain an available reflection effect, the reflection is inclined to the bottom plate. In the present paper, the availability of this method is at first claimed and the effects of the experimental conditions are investigated on the inclination of the reflector, the size and charge weight of explosive and the distance between the flyer plate and the parent one.
