ULTRASONIC SONOTRODES, METHOD FOR PRODUCING ULTRASONIC SONOTRODES, AND METHOD FOR WELDING

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