An ultrasonic real-time inspection method which is user-friendly in an interactive environment to provide ease of operation, as well as a combination of consistency, thoroughness, and speed of operation in flaw detection not achievable by other methods. The system and method are useable on a traveling wheel so as not to unduly interfere with normal train operation. The system and method includes a test device that moves along train wheels injecting pulses into the wheel to detect acoustic responses caused at a discontinuity in the wheel. A processor can also be included to determine a pattern of a feature of the wheel associated with the discontinuity.
