ABSTRACT:
An ultrasonic angle-beam probe and a method for operating the angle-beam probe include an approach wedge to be driven into a gap. The overall height of the probe sets limits which preclude testing starting from a specific gap width. At least two approach wedges are provided in order to give the angle-beam probe a testing sensitivity that is maintained even in the case of a reduced overall height. A device is provided which can be assigned to a pulse generator, a sound evaluator or a connecting element to a sound transducer, in order to influence a sound echo time.
