What Is An Ultrasonic Flaw Detector? |
|
Answer» Sound waves traveling through a material will reflect in PREDICTABLE WAYS off of flaws such as cracks and voids. An ultrasonic flaw detector is an instrument that GENERATES and processes ultrasonic signals to create a waveform display that can be used by a TRAINED operator to identify hidden flaws in a TEST piece. The operator identifies the characteristic reflection pattern from a good part, and then looks for changes in that reflection pattern that may indicate flaws.
