    摘要： NDT inspection of an austenitic weld between two CRA Clad pipes using a phased ultrasonic transducer array system is described. The method may be performed during laying of gas/oil fatigue sensitive pipelines, for example, at sea. Two types of UT inspection may be generated simultaneously by a Phased Array on each side (Upstream and Downstream) of a girth weld. Firstly, mode converted longitudinal waves are used. These waves have properties that they propagate well. Shear waves are also used. The combination of these two ultrasonic waves, with the addition of surface waves, enables 100% of the girth weld to be inspected to the standard required in fatigue sensitive welds, such as Steel Catenary Risers. Shear waves and compression waves are emitted substantially contemporaneously. Defects may be detected and measured using time of flight information and amplitudes of radiation detected on reflection and on diffraction from the defect.

    摘要： The present invention provides an ultrasound inspection method and device that can detect defect positions accurately and reduce the inspection time even when inspecting an inhomogeneous, acoustically anisotropic material. An ultrasound inspection method includes a step of creating a first flaw detection image from recorded ultrasonic waveforms, a step of creating a time-reversal propagation analysis model including loading conditions obtained from the recorded ultrasonic waveforms, and a step of creating a second flaw detection image from a result obtained by conducting a time-reversal propagation analysis on the time-reversal propagation analysis model. The method may further include a step of detecting a significant reflected signal from the first defect detection image, a step of conducting a propagation analysis to obtain respective propagation times from the significant reflected signal to respective ultrasonic wave transmission positions, a step of obtaining delay time information of the ultrasonic wave transmission positions from the propagation times, and a step of creating a time-reversal propagation analysis model including the delay times.

    摘要： A system for non-destructively characterizing laser welds that includes at least one phased array probe that includes a plurality of ultrasonic transducer elements arranged in an array at one end of the probe, wherein the transducer elements are operative to both generate ultrasonic signals and to receive reflections thereof, wherein the transducer elements are further arranged into discrete subgroups, and wherein each subgroup may be activated independently of the other subgroups and at different time intervals; a combination of materials for allowing the probe to conform to a contoured surface of a laser weld while enabling sound energy to be transferred directly into a laser weld under test conditions, wherein the combination of materials further includes a flexible membrane mounted on the end of the probe and a fluid filled chamber material disposed between the membrane and the array of ultrasonic transducer elements; and a data processor in communication with the at least one phased array probe that includes software having at least one imaging algorithm for processing data received from the probe and generating color coded ultrasonic C-scan images of a characterized laser weld.

    摘要： A method for non-destructive inspection of a weld seam. An array of ultrasonic transducers is positioned such that the array of transducers extends over at least part of the width of the weld seam. Each transducer element in the array of transducer elements is excited so that each transducer emits an ultrasonic signal. A plurality of reflected ultrasonic signals are received at the array of transducer elements and the reflected ultrasonic signals are converted to electrical signals. The electrical signals are analyzed to identify a defect, or a plurality of defects.
