摘要： A method of inspecting a preselected area of an electrically conductive component to determine whether flaws are present. The method includes the steps of permanently mounting an eddy current element on the component over the preselected area and energizing the element to generate alternating magnetic fields proximate the component. An electrical signal generated by a secondary magnetic field formed proximate the component is detected using the element and the detected electrical signal is compared to a reference signal to determine whether the detected signal is different than the reference signal. Differences indicate the presence of a flaw in the component. Inspection apparatus for performing this method is also disclosed.

摘要： A transducer position adjustment method, performed to compensate for initial ultrasonic beam alignment error, includes the steps of providing a manipulator of an ultrasonic immersion testing system having a pointing direction and supporting a transducer generating an ultrasonic beam, providing a calibration body defining a target thereon, immersing the transducer of the manipulator and the calibration body in a coupling fluid in an immersion tank of the system, setting the manipulator initially at a first position such that the pointing direction of the manipulator is aligned with the calibration body target at known coordinates, and adjusting the manipulator subsequently to a second position such that the ultrasonic beam of the transducer is brought into alignment with the calibration body target at the known coordinates for initiating an inspection of a test object after replacing the calibration body with the test object.
