  • Automated ultrasonic inspection planning
    Patent number: 6820023
    Abstract: A method for automatically generating an ultrasonic inspection plan for parts to be inspected includes collecting data relating to the ultrasonic inspection planning by displaying an input screen that prompts a user to input the pertinent data. The inspection parameters to be used in the ultrasonic inspections are then calculated from the collected data, and the calculated parameters are formatted into an inspection plan document. A tool for carrying out this method can be implemented on any computer-readable medium.

  • Phased array ultrasonic inspection method for industrial applications
    Patent number: 6789427
    Abstract: A method for inspecting a component includes exciting a number of transducers forming an array to produce an ultrasonic transmission beam (beam) focused into the component. The array and the component are separated by a standoff. A number of echo signals are generated using the transducers, and the echo signals are processed in a number of channels. The processing includes both dynamical focus and providing a dynamic aperture on receive, both of which compensate for refraction of the beam at the component/standoff interface. A single-turn inspection method includes: (a) positioning the array facing the component, (b) exciting the transducers, (c) generating a number of echo signals, (d) changing the relative angular orientation of the array and the component around an axis and repeating steps (b) and (c), and (e) processing the echo signals to form at least one processed echo signal.
