A METHOD OF EVALUATING THE SOUNDNESS OF RAILS BY USING OFF-LINE ULTRASONIC TESTING TECHNIQUE

摘要

The Invention relates to a method for evaluating the soundness of rails using ultrasonic testing. The method comprises the steps of providing a plurality of ultrasonic probes and positioning said probes on head, web and foot portions of the rails under test, and measuring the amplitude of reflected ultrasonic echo, thereby predicting location and size of a flaw.[IN238302A1]
