APPLICATION OF THE ELECTRICAL EXPLOSION OF A WIRE FOR DEFORMATION OF A SOLID BODY

Experiments were conducted in the formation of metal junctions by utilizing the electric explosion of a wire. A circuit was used. Two metal objects, a copper tube (outside diameter, 20 mm; wall thickness, 3 mm) and a steel ring (inside diameter, 20.5 mm; outside diameter, 40 mm), were joined in the following manner. The exploding wire, wound spirally around an insulated straight conductor, was inserted into the copper tube which had been previously filled with plasticine. The copper tube was then inserted into the steel ring and the wire exploded electrically. The pressure pulse, applied on the inside of the copper tube, deformed the tube radially and joined it with the ring. In this manner a very strong joint was obtained between the tube and the ring.
