Mechanical Joining Technology

Growing demands on the manufacture of energy and resource efficient products and environmental aspects are leading in many branches to an increasing use of lightweight construction concepts. The associated use of new types of material has given rise to a renaissance in particular of mechanical joining technologies in recent years. In order to give due consideration to this development, the Fraunhofer IGP is developing innovative and cost-effective solutions to the associated problems.

The field of mechanical joining technology involves various research focuses in light alloy and steel construction, in rail vehicle construction and in general motor vehicle and machine engineering. We elaborate branch-specific solutions together with our clients. The right choice and command of the joining methods go a long way to determining the functionality, reliability and safety of a construction right from the start of the product development. At the same time, the optimum joining technology for the particular application helps to save costs and material during production and use. The scope of activities extends from the advice on the choice of the optimum joining technologies through the analysis of the load-bearing strength right up to the derivation of suitable dimensioning rules, depending on the demands of the particular application.

The theoretical considerations are backed up by the accredited test laboratory of the Fraunhofer IGP that, with its modern testing technology, is able to carry out extensive experimental studies into materials, fasteners, joints and coating systems under standardised
conditions.
