Explosive cladding（explosive welding) is that two metals achieve high-speed oblique collision under the detonation of explosives, which generate high pressure and high temperature (local melting) near the collision point within a limited time (microseconds). While the high-pressure sound generated by collision plasticity causes foaming deformation of the two metals near the surface. Under the combined effects of high temperature and plastic deformation, the two metal surfaces form a metallurgical bond manifested by local melting and diffusion.
