摘要： Both a system and method are provided for mapping the magnitude of residual compressive stresses over the surface of a ferromagnetic machine component, such as a valve ring of the type used in refrigeration compressors. The system includes an eddy current probe having a detection coil for emanating a fluctuating electromagnetic field that shallowly penetrates the surface of the valve ring or other ferromagnetic component, a probe circuit connected to the coil for both conducting a high frequency alternating electric current through the coil and detecting changes in the impedance in the coil, and a scanning mechanism having a turntable for supporting and rotating the component. A support arm positions the coil of the eddy current over a central portion of the valve ring while the ring is rotated by the turntable and changes in coil impedance are detected by the probe circuit. A microprocessor converts the fluctuations in the impedance detected by the eddy current probe circuit into residual stress values, and correlates these values with regular positions on the valve ring in order to generate a map of the residual surface stresses over the ring.

摘要： A gap measurement probe for measuring the gap between a tub and an antivibration bar in a steam generator includes a shaft and first and second sensors mounted on one end of the shaft. Each of the sensors includes a coil form having a first portion fastened to the shaft and having a second C-shaped portion surrounding a portion of the periphery of the shaft. A test coil is mounted on the second C-shaped portion of each of the coil forms and the test coils are arranged such that they extend about different portions of the circumference of the shaft so as to sense different portions of the circumference of the tube when the gap measurement probe is inserted in the tube. The coil forms are flexible and have a circumference which is sufficiently large to press the test coils against the inside of the tube to provide for accurate sensing. In addition, the shaft is preset with a C shape at the end on which the sensors are mounted, so that when the probe is inserted in a U-shaped tube, the probe is self-orienting in the U bend of the tube.

摘要： An apparatus for simulating and analyzing discontinuities in a tube using eddy current inspection techniques is disclosed. The simulation apparatus includes inner and outer tubular members arranged to define an annular chamber having a predetermined tubular configuration corresponding to the tubular configuration of a tube under investigation. The outer tubular member has an opening through the wall thereof and the inner tubular member defines an axially extending hollow interior. A supply of electrically conductive liquid material is provided in the annular chamber, the quantity of liquid material being such as to substantially and completely fill the annular chamber in the vicinity of the opening through the wall of the outer tubular member. A defect simulation member is supported in the opening in the outer tubular member for movement along a predetermined direction extending transverse to the axis of the inner tubular member. Further, an eddy current test probe is positioned in the hollow interior of the inner tubular member adjacent the position of the defect simulation member for generating eddy current responses which are representative of the eddy current responses which would be obtained for a tube having a configuration corresponding to the predetermined tubular configuration and having a discontinuity in the wall thereof corresponding to the predetermined type of discontinuity.

摘要： Near-surface discontinuities, or flaws, within a workpiece are determined by transmitting acoustic energy into the workpiece. If a discontinuity is present the acoustic energy will resonate in the section of the material between the discontinuity and the surface. Acoustic energy emerging from the section as a result of the resonating is detected and analyzed to determine this fundamental frequency, from which the half wavelength and depth of the discontinuity may be determined. The procedure is also applicable for determining the thickness of relatively thin sheets of material.

摘要： An eddy current thickness probe for measuring the thickness of a weakly ferromagnetic material layer on a ferromagnetic base is provided with an essentially constant magnetic field bias. The magnetic field bias is of sufficient strength to substantially saturate ferromagnetic constituents in the weakly ferromagnetic layer. This eliminates any effects of changes in permeability of the weakly ferromagnetic layer which would otherwise impair the operation of an eddy current thickness gauge.

摘要： A method of examining a steam generator heat exchange tube from the outside surface employing ultrasonic nondestructive inspection techniques. An ultrasonic transducer contacts the outside surface of the tube and transmits a pseudo helical Lamb wave into the wall of the tube chosen to have a mode that does not significantly interact with water in the tube. The reflected waves are then analyzed for changes in modes to identify defects in the wall of the tube.
