摘要： A method for non-destructive ultrasonic testing of a test piece includes a plurality of testing cycles, each of said cycles comprising a transmitting of at least one ultrasonic impulse into the test piece by a plurality of ultrasonic transducers and a receiving of the at least one ultrasonic impulse passing through the test piece by the ultrasonic transducer or optionally by other ultrasonic transducers. The plurality of ultrasonic transducers are phase-controllable and form at least one phase array. The method comprises at least one first testing cycle in which the phase-controllable ultrasonic transducers of the at least one phase array are controlled during transmitting such that the rear wall echo of the test piece is detected by said phase array during receipt. The method comprises at least one second testing cycle in which the phase-controllable ultrasonic transducer of the same phase array are controlled during transmitting.
