The joining laboratory focusses on the development and improvement of classic and innovative joining technologies for lightweight vehicle structures in sandwich and multi-material construction.

A large and modern repertoire of systems and equipment for mechanical joining and adhesive joining is available. The laboratory is equipped with mechanical joining systems for flow drilling, self-pierce riveting, clinching, blind riveting and high-speed bolt setting. Furthermore, equipment for adhesive joining can be utilised across the entire spectrum from structurally-stiff to flexible-elastic.

By combining mechanical and adhesive joining processes, hybrid joints can also be analysed in scientific detail. The joining laboratory is equipped with a grinding and polishing machine for sample preparation and an optical microscope to analyse the joints produced both qualitatively and quantitatively.

In addition, there are further extensive analysis options in our stress and corrosion testing laboratory.
