Abstract
The invention relates to a device () for welding metal parts by means of ultrasound, in particular for welding strands, comprising a sonotrode () having a sonotrode head (), which can be excited by an oscillation generator () to perform torsional oscillations with respect to a torsion axis (B). The sonotrode head () comprises at least one welding surface () relative to the torsion axis (B) on the circumference side. Furthermore, an anvil () having a counter/compacting surface () is provided, which can be arranged opposite the welding surface () of the sonotrode () in a stationary position relative thereto. In the case of an opposite arrangement, the welding surface () and the compacting surface () delimit a compaction space () in a direction perpendicular to the torsion axis (B), said space being provided to receive the parts to be welded. The sonotrode () is designed, and coupled to the oscillation generator (), in such a manner that the entire sonotrode () can be excited to perform torsional oscillation with a negligibly small longitudinal oscillation component.
