ABSTRACT:
The performance of a magnetic pulse forming or welding process is monitored by positioning a deformation member relative to an inductor coil of the apparatus, then energizing the inductor coil to exert a force thereon. The deformation member can be a plastically deformable tube, and the amount of such plastic deformation that occurs when the inductor coil is energized can be measured to determine the magnitude of the force that is generated by the inductor coil. Alternatively, the deformation member can be an elastically deformable body, and the amount of such elastic deformation that occurs when the inductor coil is energized can be measured to determine the magnitude of the force that is generated by the inductor coil. In both instances, the magnitude of the force that is generated by the inductor coil is representative of the performance of the magnetic pulse forming or welding process and can be used, when necessary, to adjust the parameters of the magnetic pulse forming or welding processes to maintain consistency in the operation thereof.
