Securely contacting aluminium

Lightweight construction is an important trend in the automotive industry. As well as cutting down on weight – e.g. through the use of aluminium – it enables significant cost savings.

As constructors and users are ever less ready to accept compromises in material quality in favour of traditional joining technologies, however, traditional welding and adhesive processes are increasingly reaching their limits, especially when it comes to joining different types of metal. For this reason, torsional ultrasonic welding technology, often also known as high-frequency friction welding, is asserting itself as a joining technology of the future, especially in lightweight construction. A typical application is the manufacture of socalled aluminium busbars for the power supply in the engine compartment of modern vehicles.
