Enhanced Joint Properties by Magnetic Pulse Crimping with Filler Material

Article Preview

Abstract:

Compared to conventional forming joining technics, e.q. mechanical crimping, the magnetic pulse crimping gives advantages because of a contact-free tooling, a symmetrical coaxial pressure and forming, as well as a low spring back after forming. Limitations of the general functionality of crimp joints also obtain for magnetic pulsed crimp joints: Leak-tightness, combined with corrosion resistance, and a partially Limitation of electrical conductivity (transition resistance). To improve and to extend the functionality of MP-crimp-joints different filler materials can be used. By environment of a public research project, adhesives, solder and metal coatings have been applied as filler materials to MP-crimping. Within the lecture the behavior of the filler materials under the influence of high speed forming, the suitable operating conditions and achieved joint properties will be described.
