Abstract

The invention relates to an aluminum-aluminum composite material explosive welding method. The method includes: parallelly placing an lead compound plate (5) on an aluminum base plate (7) through a support (6), laying a rubber buffer layer (4) on the compound plate (5) , laying a corrugated paper layer (3) on the rubber buffer layer (4), distributing a second rock ammonium nitrate explosives on the corrugated paper layer (3), placing the base plate (7) on a flexible cushion layer (8), placing a rigid cushion layer (9) below the flexible cushion layer (8), placing a clay foundation (10) below the rigid cushion layer (9), and obtaining the aluminum-aluminum composite material through explosive welding. The welding composite rate of the aluminum-aluminum composite plate produced by the method can reach 100%, and the aluminum-aluminum composite plate is even in composition, and free of phenomena such as layering, bulking and vortex.

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 lead-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 formation....
