Schunk Sonosystems techniques

With these techniques you can realize all economically significant joining tasks.



Spot Welding

The most common application for ultrasonic metal welding is so-called spot welding. Here the size of the welding spot can range from a few square millimeters to 100 square millimeters.


Roll Seam Welding

With roll seam welding a linear continuous metallic seam weld is produced. Typical applications include solar thermal power, photovoltaics and composite pipes production.


Bending Vibration

Bending horns are often used for welding spots which are difficult get at or reach. In contrast to a standard sonotrode, which produces longitudinal oscillation, the bending sonotrode is induced to generate flexural oscillation in the center by the vibrating oscillator system.
