The electromagnetic pulse technology (EMPT): forming, welding, crimping and cutting

The electromagnetic pulse technology (EMPT) provides non-contact processes for joining, welding, forming and cutting of metals. EMPT processes can be used for joining, welding, forming and cutting of metals with particular success with those with high electric conductivity such as aluminum, copper and steel tubes. The procedure is so fast that it can produce solid-phase welds with a microstructure very similar to that of explosive welding. This article describes the fundamentals of the EMPT process, suitable machines and the economics of the process. Industrial applications of the technique are shown.
