Abstract

The invention relates to an explosive welding method of an aluminum/titanium/steel three-layer composite material, belonging to the technical field of metal composite materials. The explosive welding method is characterized in that a multi-layer aluminum (4) and a multi-layer titanium (5) are arranged on a steel plate (6) through a metal strutting (1), explosives (3) are distributed on the surface of the multi-layer aluminum (4), and an aluminum/titanium/steel composite material (8) is obtained by first-time explosive welding; a multi-layer aluminum (7) is arranged on the aluminum/titanium/steel composite material (8) by the metal strutting (1), and the aluminum/titanium/steel three-layer composite material with heavy-section multi-layer aluminum is obtained by second-time explosive welding; materials of a base plate are plain carbon steel or low alloyed steel, the thickness of the multi-layer titanium (5) ranges from 1 mm to 2 mm, and the thickness of the multi-layer aluminum (4) can reach 25mm. The invention has the advantages of high combination strength of a composite interface, no melting, layering and compositing phenomenon on the composite interface, and one time explosive welding is carried out on three layers, thereby preventing explosive welding technique parameters from being difficult to control because the multi-layer titanium (5) is extreme thin.

Description

technical field [0001] The invention belongs to the technical field of metal composite materials, and in particular relates to an explosive welding method of aluminum / titanium / steel composite materials.
