THE DEVELOPMENT OF THE PRODUCTION TECHNOLOGY OF WELDING BY THE BIMETAL EXPLOSION, STEEL + ALUMINIUM ALLOY

The object of investigation: the technology of welding by explosion and the weld connections, the high-strength steel + aluminium alloy and steel St3+technical aluminium. The purpose of the work: creating the scientifically justified production technology of the large-dimensional bimetallic sheets made from the aluminium alloys and steels of the different strength by explosion welding, on the base of study of peculiarities and laws of interaction of the aluminium alloys with steels. Obtained has been a mathematical expression for the computer design of basic parameters of the explosion welding conditions; the optimum relation of thicknesses of metals to be welded has been established; determined has been the interval of a contact point speed, in which the steel-aluminium compounds possess the optimum combination of strength and plasticity.The industrial technologies of production by the explosion welding of the bimetals: steel + aluminium alloy in the form of the large-dimensional blanks, to be protected by the Authorized Certificates.The industrial batches of bimetals have been manufactured and delivered to the Customers. The field of application: the production of the steel-aluminium adapter elements required for the ship-building and nonferrous metallurgy, and the multilayer blanks intended for the items of special purposeAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
