A kind of explosion welding method of titanium/aluminum/steel multilayer composite board

Abstract

The invention provides an explosive welding method of a titanium-aluminum-steel multilayer explosive composite board. The explosive welding method comprises the following steps of: carrying out explosive welding three times, to be specific, carrying out explosive welding for the first time by taking aluminum as a composite layer and titanium as a base layer to obtain an aluminum-titanium composite board; carrying out explosive welding for the second time by taking aluminum as a composite board and steel as a base board to obtain an aluminum-steel explosive composite board; and carrying out explosive welding for the third time by taking the aluminum-titanium composite board as a composite board, the aluminum-steel composite board as a base board and an aluminum board as an explosive joint surface to obtain a titanium-aluminum-aluminum-steel four-layer composite board which is the titanium-aluminum-steel explosive composite board in fact. When titanium, aluminum, aluminum and steel are composited through the third explosion, the upper and lower of the joint surface are aluminum plates which are low in intensity and melting point, and welding is realized by a low-detonation velocity and low-explosive load explosion method; and an aluminum-steel interface is ensured not to be stratified.

technical field

[0001] The invention relates to a solution to the problems of easy delamination of aluminum / steel, severe thinning of the aluminum plate in the middle layer, non-welding of the titanium / aluminum joint surface, etc. The explosive welding method belongs to the field of composite material manufacturing. Background technique

[0002] With its excellent corrosion resistance, titanium plate can be fully utilized under many corrosion conditions. Aluminum has the characteristics of low specific gravity and excellent electrical conductivity, making it the most cost-effective conductive material. Titanium is used as a corrosion-resistant metal, aluminum is used as a conductive metal, and steel is used as a load-bearing metal to form a titanium / aluminum / steel composite plate. The application of titanium / aluminum / steel composite plates in sodium chloride electrolytic cells fully demonstrates the superior characteristics of each group of metals (titanium is resistant to...
