Abstract

A discharge device for magnetic-pulse working and welding of metals includes two working electrodes with an igniter electrode in the form of a slotted ring placed therebetween. One of the working electrodes has a current-carrying portion connected to a working portion of the working electrode and is T-shaped, while the second working electrode is separated from the first working electrode and arranged coaxially therewith, and represents a sleeve, one end of which faces the working portion of the electrode and is provided with projections on the outside and inside so as to form a developed working portion of the working electrode.
