I²FG Impulse Forming Workshop 2016

The objective of the workshop is to bring together experts in order to present new research findings and discuss the different perspectives of future developments with respect to the technologies. It is an important forum for the exchange of knowledge and networking with the leading experts. Selected presentations of the workshop are open access.

Impulse forming

Impulse forming or high velocity forming includes all processes converting stored energy in order to form workpieces in a very short time. Electromagnetic pulse forming, joining and cutting This technology includes all production processes using the energy pulsed of magnetic fields to deform a workpiece made of an electrically highly conductive material. The following major process variants can be distinguished:

• electromagnetic compression and expansion of tubes
• electromagnetic forming of sheets
• electromagnetic welding of tubular and sheet products
• electromagnetic cutting and perforation

Vaporizing actuator forming

In this technique, electrical energy stored in a capacitor bank is released through a switched circuit that contains a thin metal conductor, such as a wire or foil. When the energy deposition rate into the conductor is very high, it can be heated above its energy of sublimation before it has time to melt. This, the conductor vaporizes directly into a gas that expands rapidly. The result is a high-pressure pulse that, when physically constrained, can be harnessed as a tool to drive workpieces.
