Abstract
It is shown that a strong joint is formed on the contact surface in explosive welding. A band of material on which plastic deformation is localized is formed along the boundary of the surface, this band representing a qualitatively new structure. Use of the laws governing strain localization, obtained from a study of the collapse of thick-walled cylinders that were subjected to explosive shock loading, makes it possible to predict the collision parameters in explosive welding in accordance with the grain size of the materials that are used.
