An ultrasonic welding device includes a sonotrode, an anvil, a touching element, a lateral slide, a stop element and a receiving chamber in which joining partners are received and which is defined by bordering components of the ultrasonic welding device. The receiving chamber is defined on a first side by the sonotrode and on a second side by the anvil. The receiving chamber is further defined on a third side by the touching element and on a fourth side by the lateral slide. The receiving chamber is further defined on a fifth side, extending transverse to the first to fourth sides, by the stop element. The first stop element is electrically conductive on its surface directed toward the receiving chamber in order to form a first electrode.

The invention relates to ultrasonic welding tongs () for performing ultrasonic welding on a tubular electrically conductive welding medium (), wherein a first welding jaw or a second welding jaw and a welding-medium stop device (), which delimits a welding-medium holding space () formed between the welding jaws, are each electrically conductive and arranged electrically isolated from each other, the electrically conductive welding jaw and the electrically conductive welding-medium stop device forming components of a safety circuit in such a manner that a welding process including a closing of the welding jaws is triggered after the safety circuit has been closed by the formation of an electrical contact between the electrically conductive welding jaw and the welding-medium stop device by way of the welding medium.

The invention relates to a method for measuring and/or regulating the oscillation amplitude of an ultrasound oscillator of an ultrasound device. In order to be able to measure or regulate the oscillation amplitude of the ultrasound oscillator in a simple manner, it is proposed that a sensor capturing the oscillation amplitude be associated with at least one component element of the ultrasound oscillator.
