TORSION SONOTRODE AND ULTRASONIC WELDING PROCESS USING A TORSION SONOTRODE

摘要

The invention relates to a torsion sonotrode (S) having a contact surface (1, 1') for transferring a torsional oscillation directed about a torsion axis (T) onto a component (4) to be welded. To ensure that the welded joint has a uniform strength, it is proposed according to the invention that the contact surface (1, 1') has a flat stop surface (2, 2') which runs substantially perpendicular to the torsion axis (T) and from which elevations (3, 3') of insular design extend with a pointed form.
