A connecting element for connecting and/or fixing an electrode with an electrode arm of a welding apparatus has a base body; and a sensor selected from the group consisting of a sensor for introducing ultrasound waves into an electrode, a sensor for receiving ultrasound waves and both.

Electrode holder with integrated ultrasound sensor

The invention relates to an ultrasound sensor system, especially for a welding electrode, comprising a sensor () which, during the detection process, passes ultrasonic waves of a desired oscillation mode into areas to be detected and/or detects ultrasonic waves. At least one material recess () is provided in a sensor support (), and at least one sensor () is arranged in said recess.

Ultrasound sensor system

A sensor carrier is provided that has at least one oscillating element () that introduces ultrasonic waves into an area to be examined and/or receives ultrasonic waves coming from the area to be examined, whereby the oscillating element () is located in an oscillator carrier (), and the oscillator carrier () has connecting means () for connection with the electrode ().

Ultrasonic sensor for controlling the process during resistance spot welding

The invention relates to an ultrasonic sensor system, especially for controlling a resistance welding process. Said system comprises at least one receiver which is used to detect the ultrasonic signals from the area to be examined. At least two piezoelectric sensors () are used as a receiver and are arranged in such a way that their polarization direction vectors indicate various directions, said vectors being projected in a plane perpendicular in relation to the propagation direction of an ultrasonic wave to be detected.
