Abstract

The invention relates to an explosive welding method for a copper-aluminum composite material. An aluminum composite plate (4) is arranged on a copper substrate (6) in a parallel mode through a supporting object (5), a rubber buffering layer (3) is laid on the aluminum composite plate (4), rock ammonium nitrate explosive cloth number two is arranged on a rubber buffering layer (3), the copper substrate (6) is arranged on a rubber cushion layer (7), a medium-fine sand foundation (8) is located below the rubber cushion layer (7), and the copper-aluminum composite material is obtained through explosive welding. A copper-aluminum composite plate produced through the explosive welding method can achieve 100% welding composite rate, is evenly formed in a composite mode without the phenomena of layering, swelling, vortex and the like.

Description

[0001] technical field

[0002] The invention belongs to the technical field of explosive composite of metal materials, and in particular relates to an explosive welding method of copper-aluminum composite materials. Background technique

[0003] Explosive welding technology (commonly known as explosive composite) uses explosives as the energy source, and through the detonation effect of explosives, one material (layer) collides with another material (base layer) at high speed to realize the metallurgical bonding of the two metals, and the bonding area appears as Corrugated metallurgical bond. Metal explosive composite materials are widely used in electronic power, aerospace, shipbuilding, marine engineering, petrochemical, metal smelting, nuclear industry and other industries and fields. At present, the explosive welding technology of metal sheets is immature, and the welding products have low recombination rate, unevenness, easy delamination, drumming, and vortex formatio...
