摘要： A method for the nondestructive testing of a test object by ultrasound, 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, by the ultrasonic transmitting transducers each being 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, 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.

摘要： 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 (x n ) by means of at least one ultrasonic transducer, comprising a plurality of steps. First, a calibration device (20) with known dimensions (OD cal (x n )) is provided. Then there follow several calibrating steps, during each of which a measuring position specific distance (WP(x n )) 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 (OD cal (x n) ) 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 x n , using at least one echo on at least one surface (26) of the test object (28). In the following evaluation step a dimension (27) of the test object is calculated using the measuring position- specific distances WP(x n ).

摘要： The invention relates 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 (6), an ultrasonic pulse (5) is obliquely incident into a sound incidence surface (7) of a test object (10). Next, an echo signal (22) is received from the test object (10). This takes place either by means of the ultrasonic transducer (6), which has emitted the ultrasonic pulse (5) or with another ultrasonic transducer. The time amplitude characteristic (20) of the echo signal (22) is evaluated in a predefined defect expectation interval of time (26). The evaluation step includes, in at least one section (30) of the amplitude characteristic (20), an amplification of the amplitude (A) and/or a reduction in the threshold value (26). For example, the amplitude (A) of the received echo signal (22) is then compared with the predefined threshold value (26).
