IMPROVED METHOD OF DETERMINING SIZE OF TRANSVERSE DEFECTS

Ground inspection of rail defects following identification by detector cars is performed by hand-held ultrasonic flaw detectors in the echo-pulse mode. In addition to verifying defects, their character and size are also identified. As a part of its program on cost-risk analysis of defective rails, AAR has studied these portable instruments with particular attention to transverse defects. It has been possible to characterize defects and the process would be enhanced by a programmable calculator for computing the flaw size and profile.
