Empt coil with exchangeable conductor

Abstract

An electromagnetic pulse welding coil includes a first conductive region and a second conductive region. The second conductive region is assigned to a remainder of the coil and has a low current density. The first conductive region is configured for generating a higher current density than the second conductive region. The first conductive region is detachably connected to the remainder of the coil using a detachable connection. The electromagnetic pulse welding coil is planar in design and is cut out of a metal plate.
