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： According to the invention, ultrasound is emitted by a probe and travels over a defined distance to reach a test object (32), and at least one echo signal (51) of the irradiated ultrasound is detected by the probe. The central beam of the ultrasound does not fall upon the surface of the test object (32) at a right angle. A reflection surface (38) is provided between the probe and the test object (32), said surface being outside the central beam, but inside the sound field of the probe. The reflection surface is arranged in such a way that the part of the emitted ultrasound which falls on the reflection surface (38) falls, after reflection, in an essentially right-angled manner on the surface of the test object (32), and is then reflected back therefrom and used as a signal (51) for an echostart. Said probe is a linear array comprising n individual oscillators (22, 24...). A reflection surface (38) is associated with each individual oscillator (22, 24...), and an echostart signal (51) is produced for each individual oscillator (22, 24...). The reception signals (52, 54) which are received by each individual oscillator (22, 24...) are digitalised. Said digitalisation is started individually for each individual oscillator (22, 24...) by means of the echostart signal (52, 54) of the individual oscillator (22, 24...).

摘要： 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.

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).

摘要： The invention relates to an ultrasonic test method having an ultrasonic test step, wherein a test item is checked non-destructively by means of ultrasound generated by an ultrasonic test head, wherein a liquid coupling medium continuously circulates outside of the test head. Part of the coupling medium is diverted and fed into a coupling chamber between the ultrasonic test head and the test item. The coupling agent circuit also comprises a degassing device. Gas bubbles in the coupling agents are removed from the coupling agent by means of a settling tank and a zigzag conduit.
