Explosive welding: principles and potentials

摘要: 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 joined with high-quality metallurgical bond. (or bonding) high-pressure contaminant surface films are plastically jetted off the base as result of collision metals. time duration involved event so short that reaction zone heat affected zone) between constituent microscopic. During process, first few atomic layers each metal become plasma because velocity impact (200 to 500 m/s, 660 1,640 ft/s.) angle causes jet front point, effectively scrub-cleaning both surfaces, and leaving clean behind.
