Abstract:
Method and apparatus for the non-destructive inspection of a test object with a large material thickness by means of ultrasound. The apparatus includes an ultrasonic test probe with an ultrasonic transducer divided into a plurality of individually activatable transducer segments wherein the transducer segments are concentric circles or rings, or sections thereof. A first group j (j=1, 2, 3, . . . ) of transducer segments is selected in such a way that a parallel activation of these transducer segments results in a circular active surface Fj of the ultrasonic transducer (22). An ultrasound inspection of the test object is undertaken with the first group j (j=1, 2, 3, . . . ) of transducer segments, wherein they are activated in parallel.
