Ultrasonic welding is mainly suitable for copper and aluminum connections. The process requires little energy and is fast. Components joined by ultrasonics provide high strength and excellent electrical conductivity, since the vibrations destroy oxide layers and remove impurities on the metal surfaces. Contact resistances, such as those taking place during soldering or crimping do not occur. Reproducibility of the process sequences is important for precise and efficient production with a high degree of quality monitoring. The quality of ultrasonically welded connections therefore heavily depends on application-specific process development. In the laboratory at Herrmann Ultraschall we systematically determine the optimum process parameters for your ultrasonic weld task and design the perfect weld system for your production environment.
