Main kinematic and energy-related aspects of the formation of two-layer and multilayer joints upon explosive welding of metals are considered; the principal characteristic regions of this process are shown; the critical energy boundaries depending on the Astrov criterion have been established. The kinematics of plastic flow of metal in the heat-affected zone upon explosive welding under various regimes of collision has been studied; the energy balance in the system of collided plates has been analyzed. A new parameter for characterizing the process of explosive welding has been suggested, namely, the magnitude of a deforming pressure momentum. A mathematical model that describes the process of the acceleration and interaction of metallic plates in a multilayer packet upon welding with a simultaneous cladding scheme is presented. The main fields of practical application of layered composite materials produced by explosive welding are shown.
