METHOD FOR MAKING NON-DETACHABLE JOINTS BY EXPLOSION WELDING Russian patent published in 2002 - IPC

Abstract RU 2185942 C1

FIELD: manufacture of flat blanks by explosion welding of steel with aluminum, titanium, steel. SUBSTANCE: method comprises steps of placing between charge of explosion matter and propellant plate intermediate wedge-shaped member of inert material with angle 3-20 degrees. Relation of specific mass of intermediate member to specific mass of propellant plate is in range (0.009-0.6). Relation of specific mass of intermediate member to that of charge of explosion matter is in range (0.0036- 1.129). It is possible to control in wide range speed of contact spot at welding due to changing inclination angle of surface of intermediate member and its material. EFFECT: improved quality of welded joint. 1 dwg
