Abstract

The invention relates to a method for explosively welding copper-silver composite materials. The method includes parallelly arranging a silver composite plate (4) on a copper base plate (6) via supports (5); laying a corrugated paper buffer layer (3) on the composite plate (4); arranging second rock ammonium nitrate explosives on the corrugated paper buffer layer (3); placing the base plate (6) on a corrugated paper cushion (7); arranging a rubber cushion (8) under the corrugated paper cushion (7); positioning a clay foundation (9) under the rubber cushion (8); explosively welding the components to obtain a copper-silver composite material. The method has the advantages that the welding composite rate of copper-silver composite plates manufactured by the method is 100%, and the copper-silver composite plates are uniformly composited and are free of phenomena such as layering, bulging and vortexes.

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-silver 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 formation....
