ABSTRACT:
A welding system includes a device for evaluating an ultrasonic signal during a welding process. The device has a meassured value evaluation unit that, in normal operation, evaluates at least one measurement signal that is derived from an ultrasonic signal and is located inside a measurement window. A mechanism for establishing the measurement window is provided, which establishes the measurement window according to a measurement signal that is received in a calibration operation.
