Abstract

The invention discloses a manufacturing method of an aluminium-copper double metal composite weldment, which comprises the following steps: a composite aluminium plate (4) is supported layer by layer by a support (5) and is arranged on a base copper plate (6); a buffering protective layer (3) is stuck on a first layer of aluminium plate (4); explosives (2) are distributed on the surface of the buffering protective layer (3); the explosive load on a unit area is controlled according to the requirement of design strictly; the aluminium-copper double metal composite material with high quality is obtained by integrating explosion, welding and composition, the composite interface has high and uniform bonding strength; the interface does not have excessive melting and composite layering, does not lead the resistance of the interface to increase, can realize explosion and welding on a large area, is convenient to product and improves the efficiency.

Description

technical field [0001] The invention relates to the technical field of metal composite material manufacturing, in particular to a manufacturing method of an aluminum-copper bimetal composite weldment. Background technique [0002] At present, the aluminum-copper bimetallic composite weldments used were mostly manufactured by casting composite method in the past; the disadvantages are that there are many defects such as looseness and microcracks at the interface of the two metals, and the bonding strength is low, which makes it difficult to meet the requirements of large density. Design and use requirements when current is passed. In addition, it is also difficult to withstand subsequent stamping deformation, and the interface is easy to delaminate. [0003] There is also an explosive welding method. Usually, this explosive welding method can make the cladding metal collide with the base metal at high speed under the explosive load of explosives, and form a firm interatomic ...
