EXPLOSION WELDING METHOD Russian patent published in 2005 - IPC

Abstract RU 2243871 C1

FIELD: mechanical engineering; welding.

SUBSTANCE: invention can be used for connecting two or several metal parts. Facing (throw) plate is installed with clearance over base plate and charge of explosive arranged over facing plate is initiated. Preliminarily surfaces of plates to be welded are machines to roughness R_z=8.0-12.0 mcm. Welding is done by pressure of detonation products. Time of action of said products. Time of action of said products exceeds time of cooling of surface layers of plates melted to depth exceeding 2 mcm.

EFFECT: provision of multilayer material featuring high processing and operating characteristic with any combination of metals and alloys.
