Position Tracking and Flaw Visualization in Conductive Materials
نویسنده
چکیده
The Eddy current technique has been successfully used in a variety of non-destructive evaluation applications including detection of cracks, measurements of material thickness, examining metal thinning, measurements of coating thickness, identification of materials, and detection of corrosion. This paper shows how positional and eddy-current data are combined to produce a C-scan of flaws in conductive materials. A system that consists of an eddy current probe, a position tracking mechanism, and basic data visualization capability was built and tested. Test results of the prototype are presented and briefly discussed. Improving the accuracy of the measurements using a three-mouse position sensing device is described. Key-Words: Position tracking, non-destructive evaluation, eddy current, visualization

متن کاملDetection and Visualization of Flaws in Ultrasonic Defectoscopy
In ultrasonic defectoscopy it is very difficult to detect flaws in materials with coarse-grain structure. Measured ultrasonic signal contains echoes from flaw and echoes from grains included in material. These echoes characterized noise have to be cancelled. A common source of noise is electronic circuitry, which is used for processing of the ultrasonic signal, and scattering at the inhomogenei...
متن کاملBoundary Integral Equations for Modeling Arbitrary Flaw Geometries in Electric Current Injection Nde
The Electric Current Injection (ECI) method of nondestructive evaluation is applied to materials that are electrically conductive but not magnetically permeable, such as aluminum, magnesium, and titanium. It consists of detecting current-flow anomalies due to voids, nonmetallic inclusions and open cracks in the conducting material, through distortions introduced in the magnetic field generated ...
