How to meet Assembly Issues in Lightweight and Mixed Materials ScenariosThe Diversified Palette of Joining Methods for the Car Bodies of Today andTomorrow

摘要

This paper will pin-point the following topics:rn? The usage of a comprehensive materials selection in order to meet up-coming lightweightrndemands, covering advanced high strength steels (AHSS), stainless steels, aluminium,rnmagnesium and fiber-reinforced plasticsrn? The selection of appropriate joining methods in such a mixed materials scenario, e.g. laserrnwelding, brazing technologies as well as mechanical joining and adhesive bonding systemsrnadapted to high volume productionrn? The utilization of innovative joining methods as enablers for the introduction of "new"rnproduction technology, like hot-forming, hydro-forming and roll-formingrn? Successful application examples where the introduction of alternative joining methods, eitherrnhas helped overcome quality and cost problems, or through the high assembly quality hasrnimproved the performance of the car bodyrnA philosophic discussion about the expected direction of development and usage of variousrnjoining methods in car body concepts beyond tomorrow will conclude the presentation.
