Abstract

The invention discloses a self-constraint structure explosive for explosive welding. The self-constraint structure explosive comprises a structure explosive and a welding device. Through the constraint effect of detonation of a high-detonation-speed explosive on a low-detonation-speed explosive, energy dissipation of the explosive is reduced, and the utilization efficiency of the welding explosive amount is improved. A large amount of economic cost is saved for explosive welding production, and high economic value and practical value are achieved.

Description

technical field [0001] The invention relates to the related field of explosive welding technology, in particular to a self-contained structural explosive for explosive welding. Background technique [0002] Explosive welding is a composite process integrating fusion welding, pressure welding and diffusion welding. It utilizes the explosion energy of explosives to convert the kinetic energy of the cladding, so that the cladding and the base layer collide at a high speed at the metal interface to produce metallurgical bonding. As a special composite process, explosive welding (or explosive composite) is widely used in chemical pipelines, machinery manufacturing, nuclear power plants, aerospace and other fields. welding. Explosive compounding generally uses low-detonation velocity explosives as the driving charge of the doubler plate. Most of the energy of the welding explosive explosion is released in the form of shock waves and detonation products, which are dissipated into...
