    Abstract: A non-destructive testing system includes directing guided wave energy to regions of interest in waveguides. Knowing the propagation paths taken by guided wave energy in complex waveguides can be used to intentionally insonify regions of interest. Additionally, knowledge of the propagation direction and location of an energy mode in a waveguide allows the calculation of the path previously taken by the energy mode. This information can be used for signal processing of guided wave inspection systems. The test system can have various sensor configurations including: a single transducer configured to direct or receive guided wave energy along a particular direction, a one-dimensional array or a two dimensional array of transducers. The transducers can operate independently to provide mutual phasing and amplitude adjusting to steer guided wave energy in a waveguide or determine the directionality of guided wave energy received by the sensors.

  • Patent number: 9192355
    Abstract: Increasing the effective aperture of an ultrasound imaging probe by including more than one probe head and using the elements of all of the probes to render an image can greatly improve the lateral resolution of the generated image. In order to render an image, the relative positions of all of the elements must be known precisely. A calibration fixture is described in which the probe assembly to be calibrated is placed above a test block and transmits ultrasonic pulses through the test block to an ultrasonic sensor. As the ultrasonic pulses are transmitted though some or all of the elements in the probe to be tested, the differential transit times of arrival of the waveform are measured precisely. From these measurements the relative positions of the probe elements can be computed and the probe can be aligned.

A-scan data corresponding with conventional preferred inspection incidence angle is selected, and reject levels are set to 0% to meet current inspection standards. S-scan data allows for detection of flaws that might otherwise be undetectable using only A-scan data. A palette adjustment feature remaps the colors assigned to lower intensity return values so that they are not displayed on the S-scan, thereby de-cluttering sectorial data without filtering A-scan data.

  • Patent number: 8596126
    Abstract: A method and apparatus for collecting ultrasonic test data from a railway wheel with an ultrasonic testing apparatus is described. The railway wheel is supported by two drive rollers, each having an indentation which engages with and rotates the wheel. An indexing transducer moves across the rotating wheel, collecting ultrasonic test data while a fixed transducer correlates a reference position on the wheel to the collected test data. To maintain the accuracy of the reference position to the collected test data, it is desirable to maintain the rotational stability of the wheel, minimizing any dynamic instability caused by dimensional tolerances in the wheel. To mitigate instabilities resulting from dimensional tolerances, the indentation of the drive rollers, which engage and drive the flange of the wheel, is adjustable by the flexing design of the drive rollers to maintain frictional contact between the wheel and the drive roller.

  • Patent number: 8459120
    Abstract: A method and apparatus for ultrasonic inspection of one or more parts, in which one or more parts to be inspected are transferred from a parts carrier to a scan nest that is located in the scanning station. The parts are restrained in the scan nest and then scanned. A pick and place mechanism is used to transfer the parts to be inspected between the parts carrier the scan nest. The inspection path may be altered if a missing part is detected. In one embodiment, a first gas flow port located on the pick and place mechanism or on the transducer holder is used to blow ultrasonic coupling fluid from the front surface of the parts in the scan nest after they have been scanned. In a further embodiment, two or more scan nests are used for parallel operation.

  • Patent number: 8453508
    Abstract: A computer with a proper program generates a phased array sequence of signals. In a pulser with delays, the signals are fed through a multiplexor into a water wedge that is attached to a valve being tested. For a sequential operation of the valves from the open to the closed position, ultrasonic signals are transmitted through the fluid contained in the valve and reflected back through piezo-electric crystals to the multiplexor. By summation and merger of the signals, an image can be developed of the operation of the valve to determine if the valve is operating properly. By use of the water wedge, the top plate of the valve appears to disappear because the water wedge has the same refractive angle as the fluid contained in the valve.
