  • Publication number: 20230059369
    Abstract: A method of monitoring a portion of an equipment under pressure implementing a control station to control an ultrasonic non-destructive testing device through a remote network, includes: the control station sends a first measurement request to the non-destructive testing device; the control station receives a first plurality of measurement data from the non-destructive testing device, constructs a first mapping of the portion of the structure from the data; sends a second measurement request to the non-destructive testing device, receives a second plurality of measurement data from the non-destructive testing device, constructs a second mapping of the portion of the structure, from the second plurality of measurement data, and compares the first mapping and the second mapping.

  • Patent number: 7168322
    Abstract: The invention concerns a method for non-destructive ultrasonic control, combining time-of-flight diffraction (TOFD) and inclined longitudinal wave techniques, of weld joints assembling two abutted parts. The method consists of using the time-of-flight diffraction technique, displacing in the longitudinal or circumferential direction, along the weld joint to be controlled, at least one pair consisting of a first transducer and of a second transducer, one transmitting and the other receiving ultrasonic waves, these transducers being laterally positioned on either side of the joint to be controlled, these transducers comprising piezoelectric ceramics or crystals. Furthermore, it consists of displacing along the welded joint to be controlled, using the inclined longitudinal wave technique, at least a third transducer, so as to detect any defect of the joint located at a thickness ranging between 0.5 mm and 15 mm.
