Abstract

A novel explosive welding technique which uses underwater shock waves to weld thin sheets and the technical advantages of this technique are reported. Using this technique, a thin metal plate is uniformly accelerated by underwater shock waves. The initial angle of inclination of the explosive pack is determinant in high-explosive welding systems, with respect to decreasing the horizontal collision velocity. Any change in the welding conditions along the cladding plates influences the weld strength and, therefore, the parameters should be judiciously selected so as to lie within the weldability boundary. The size of the waves generated at the welded interface is discussed based on the angle of collision. Future applications for multilayered explosive welding are also suggested.
