Electromagnetic Forming and Joining of Tube and Sheet Metal

Co-authors NEUGEBAUER Reimund, PSYK Verena

Based on the use of new materials it is necessary to find the available forming technology for specific material properties. Fraunhofer Institut IWU develops new forming technologies for applications of sheet metal and tubes since many years. Beside the conventional forming technologies the electromagnetic forming (EMF) offers to shape new geometries by a very small energetic power consumption. The most important application of EMF is joining by compression of tubular workpieces. Electromagnetic forming makes use of the interactions between materials with good electrical conductivity and high power magnetic fields created by a pulsed current flowing through a tool coil. The target-oriented exploitation of the process specific advantages of EMF for the economic production of parts is an important aim of our research.
