Fabricating automotive spaceframes using electromagnetic forming or magnetic pulse welding

摘要

A method for fabricating an automotive spaceframe using Electromagnetic Pulse Forming (EMF) or Magnetic Pulse Welding (MPW) techniques. The spaceframe can be either an all aluminum structure or a combination of dissimilar materials, such as aluminum and steel. The welding or forming methods can include the use of split coils or split inductors that allow for ease of access to the joints to be bonded in the spaceframe.
