摘要： To test transverse flanges terminating at a cylindrical wall of a workpiece, an installation includes a structure in a form of a U-shaped or C-shaped stirrup whose opposite branches carry respectively an ultrasound emitter transducer and receiver transducer, aligned with respect to one another, while leaving between them an internal space for relative passage of the flange to be tested, and whose base is mounted articulated at an extremity of a mobile control arm. The installation also includes an immersion canister including two parts assembled together by a closure mechanism, one of the parts exhibiting cutouts for engaging the transverse flange and for overlapping, with the other part, the flange up to the cylindrical wall of the workpiece.

摘要： An ultrasonic measurement device and method in which an ultrasonic transducer is acoustically coupled to an object to be measured by a resilient material contact layer. The transducer transmits a plurality of consecutive ultrasonic transmit signals into the object being measured, the transmit frequency of each of the plurality of transmit signals being distinct from the frequency of the other transmit signals of the plurality of transmit signals. Signal echoes of the transmitted signals are received, and based on the received signal echoes, at least one transmit frequency to be used for ultrasonic measurement of the object is selected.

摘要： An apparatus and method for ultrasonic non-destructive testing provides an elongate strip of ultrasound transmissive material coupled at a proximal end to an object under test. The elongate strip has a transverse cross-section with a width and thickness giving an aspect ratio greater than unity and matched to the ultrasonic transducer such that excitation induces a substantially non-dispersive ultrasonic signal to propagate along the elongate strip to the proximal end and to enter the object under test. These non-dispersive pulses are particularly suited for time-of-flight measurements, thickness measurements, crack measurements and the like. The elongate strip helps to separate the transducer from a potentially hostile environment associated with the object under test. The elongate strip also has a large area of contact with the object under test allowing efficient transmission of energy into the object under test.
