Article: Explosive welding: principles and potentials.

Explosive welding is a solid-state process in which controlled explosive detonations force two or more metals together at high pressures. The resultant composite system is joined with a high-quality metallurgical bond. Roots of the process stretch back to World War I, when ordnance and explosive specialists witnessed bombshell fragments adhering to metallic objects in the vicinity of the explosion. At the time, no one recognized the industrial potential of explosively bonded materials. It was not until 1962 that the practicality and potential of the process were realized.
