Abstract: A method for the nondestructive testing of a test object by ultrasound is provided, the method including generating a pulsed ultrasonic field in the test object by means of an array of individually drivable ultrasonic transmitting transducers acoustically coupled to the test object. The ultrasonic transmitting transducers are each driven with a specific analog transient excitation signal, wherein each analog transient excitation signal is generated based on an ultrasonic transmitting transducer-specific stored digital transient excitation function. The method further includes receiving resulting echo signals from the test object by means of an array of individually drivable ultrasonic receiving transducers, with each ultrasonic receiving transducer providing an analog time-resolved echo signal, temporarily storing the time-resolved, transducer-specific, digitized echo signals in the form of an echo signal set, and applying a plurality of different reception processing rules to the echo signal set.

Abstract: Embodiments relate to a method for ultrasonic testing according to the pulse-echo method as well as an arrangement for performing such a method. By means of an ultrasonic transducer, an ultrasonic pulse is obliquely incident into a sound incidence surface of a test object. Next, an echo signal is received from the test object. This takes place either by means of the ultrasonic transducer, which has emitted the ultrasonic pulse or with another ultrasonic transducer. The time amplitude characteristic of the echo signal is evaluated in a predefined defect expectation interval of time. The evaluation step includes, in at least one section of the amplitude characteristic, an amplification of the amplitude and/or a reduction in the threshold value. For example, the amplitude of the received echo signal is then compared with the predefined threshold value.

Abstract: The invention relates to a method for ultrasonic geometry testing of a test object (28) at various measuring positions distributed along a surface (26) of a test object (xn) by means of at least one ultrasonic transducer, comprising a plurality of steps. First, a calibration device (20) with known dimensions (ODcal(xn)) is provided. Then there follow several calibrating steps, during each of which a measuring position specific distance (WP(xn)) between calibration device (20) and ultrasonic transducer (10) is determined and stored by an ultrasonic transit time method, by at least one echo on at least one surface of the calibration device (20), using the known dimension (ODcal(xn)) for each measuring position n. Subsequently, a test object (28) is provided, at which ultrasonic transit time measurements are performed in multiple test steps. Transit time measurements are thereby taken at several measuring positions xn, using at least one echo on at least one surface (26) of the test object (28).
