Abstract

In an apparatus and a method for welding of workpiece layers, a feed device is activated with a predefined adjustment force without ultrasound activation and the sonotrode is advanced in the direction of an anvil. The adjustment force is subsequently reduced and the sonotrode is activated. The sonotrode can subsequently be deactivated and the adjustment force can be increased on the basis of a deactivation signal.
