Natural Rail Surface Defect Inspection and Analysis Using 16-Channel Eddy Current System

Trains are used as the fastest mode of transportation for both people and cargo. The train moves along a special path called “rail”, where fatigue can be accumulated due to wheel-rail contact load result continuous operation. Consistent regularly scheduled safety management is required since corrosion rate rails located on outside environment very high. Researchers have actively investigated developed rail defect inspection systems employing non-destructive techniques address these problems. In particular, eddy current technique does not involve with surface test specimen offers advantage excellent detection sensitivity. Therefore, 16 Channel array device was inspect defects rail. An equation derived predict correlation between depth phase an artificial using device, applied natural specimen.
