Abstract
An apparatus has a single workstation for joining high strength metal components by electromagnetic forming techniques. One of the metal components carries high loads or is subjected to combined stresses and strains, thus requiring that it be relatively strong and ductile. EMF or MPW processes are used to join the components, whose strength is temporarily diminished prior to the joining step. The high strength material is subjected to a retrogressive heating and quenching process along a joined boundary thereof and is then electromagnetically joined. Thereafter, the strength of the diminished material is restored to its higher temper and strength. In a first embodiment, the apparatus uses a single coil for both the heating and electromagnetic bonding of the metal. In a second embodiment, two adjacent coils are used and the material is moved along a work path between the coils.
