ABSTRACT:
An ultrasonic welding device for welding two components has a rod-shaped first sonotrode for the generation of longitudinal waves and is coupled on its first end to a first converter and on its second end opposite the first end to a second converter. A first welding surface is provided in the middle of the first sonotrode. To improve durability and welding performance, a second sonotrode which is coupled to at least one third converter and is configured as a torsion sonotrode, has a second welding surface arranged opposite the first welding surface. The first and second sonotrodes can be moved relatively to each other such that a clamping force between the first and the second welding surface can be applied to the components to be connected.
