Ultrasonic sonotrodes, method for producing ultrasonic sonotrodes, and method for welding

Abstract

An ultrasonic sonotrode (10) is disclosed, comprising a base body (1) with a coupling surface (3) for coupling ultrasonic vibrations and a processing pin (2) extending along a longitudinal axis (L) with a working surface (4) for emitting the ultrasonic vibrations to a component (21), in particular a welding surface (4) for welding the component (21). The processing pin (2) is connected to the base body (1) by material bonding and/or force fitting. Also disclosed is a method of manufacturing such an ultrasonic sonotrode (10). The method includes a step in which the processing pin (2) is connected to the base body (1) by material bonding and/or force fitting. Also disclosed is a method of welding at least two components (21) by means of the ultrasonic sonotrode (10).
