Abstract:
A method may involve positioning a fixture over a portion of a tube portion of a gasket, where the gasket includes a first lip portion joined to a second lip portion by a weld of the gasket and the first lip portion joined to the second lip portion defines the tube portion, where the fixture comprises a housing and an injection port; positioning an ultrasonic probe in the housing; filling, by the injection port, coupling fluid between the ultrasonic probe and the tube portion of the gasket; and scanning at least a portion of the weld with the ultrasonic probe, where scanning the at least a portion of the weld may involve transmitting, by the ultrasonic probe, a plurality of ultrasonic waves through the coupling fluid into the tube portion, and translating the fixture in a longitudinal direction along the tube portion of the gasket.
Abstract:
A method and apparatus is presented. A signal may be sent into a structure at an incidence angle from a transducer array. A response signal reflected from the structure in response to the signal sent into the structure may be detected at the transducer array to form a received response.
Abstract:
A plurality of subsets of ultrasonic transducers in an array of ultrasonic transducers are configured to transmit ultrasonic waves at various angles simultaneously toward a test object so that an anomaly of any orientation in the test object can be detected efficiently.
Abstract:
The invention relates to a method for the non-destructive testing of a test object (100) by way of ultrasound, said method comprising the following steps: (a) radiating directed ultrasonic pulses into the test object (100) at an irradiation angle ß, said irradiation angle ß being set electronically, (b) recording echo signals that result from the ultrasonic pulses radiated into the test object (100), (c) determining an irradiation position X0 in which echo signals can be recorded that can be associated with an error (102) in the volume of the test object, (d) determining the irradiation angle ßmax for which the ERS value of the error (102) reaches its maximum at position X0, (e) changing the irradiation position X0 ? X1 on the surface of the test object (100), the change of the irradiation position being captured, (f) electronically adjusting the irradiation angle ß in such a manner that the ERS value of the error (102) reaches its maximum in the changed irradiation position X1. The invention further relates to a device which is suitable for carrying out said method.
Abstract:
Gegenstand der Erfindung ist ein Verfahren für die zerstörungsfreie Prüfung eines Prüflings 100 mittels Ultraschall, welches die folgenden Verfahrensschritte umfasst: a. Einschallen gerichteter Ultraschallpulse in den Prüfling 100 unter einem Einschallwinkel ß, wobei der Einschallwinkel ß elektronisch eingestellt wird, b. Aufnehmen von Echosignalen, die aus den in den Prüfling 100 eingeschallten Ultraschallpulses resultieren, c. Berechnen eines ERS-Werts eines Fehlers 102 im Volumen des Prüflings aus Echosignalen, die dem Fehler 102 zugeordnet werden können Weiterhin betrifft die Erfindung eine Vorrichtung zur Ausführung des Verfahrens.
Abstract:
A method for use in connection with installing a cable into a conduit having a first conduit end and a second conduit end, comprising the steps of - providing the cable with a metallic attribute, - providing within or proximate to the conduit, sensing means for sensing the metallic attribute, - introducing the cable into the first conduit end and driving it towards the second conduit end, and - detecting that the sensing means has sensed the metallic attribute by sensing a change in inductance levels of the sensing means.
