Problems solved by technology

[0003] The technical problem to be solved in the present invention is that when the thin titanium clad layer is welded with the steel plate explosively, the process parameters are difficult to control, and it is easy to cause a large number of molten layers to appear at the titanium / steel composite interface due to excessive recombination energy, thereby forming brittle iron-titanium intermetallic compounds , which eventually leads to the problem of poor bonding strength at the titanium / steel composite interface

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
