Learn about the ultrasonic method. This method uses special tools to send high-pitched inaudible sound waves through your parts to verify you have no internal delaminations.
- [Instructor] Ultrasonic instruction…has proven to be a very useful tool…for the detection of internal delamination,…voids, inconsistencies, and or discontinuities.…Now, with ultrasonic inspection…you're able to use various sound waves and techniques…to find things that you would normally not find…with just a simple visual inspection…or a tap test.…The method used is basically an energy wave…with a frequency that is above the audible range.…
When an ultrasonic wave strikes an interrupting object,…that void or the delamination or the inconsistency…or discontinuity, the wave is disrupted, or diminished.…The diminished sonic energy is then picked up…by a receiving transducer, and converted into a display…on an oscilloscope or a chart recorder.…The display allows the operator to evaluate…the discrepant indications comparatively…with those areas known to be good.…To facilitate the comparison,…reference standards are established and utilized…to calibrate the ultrasonic equipment.…
Pulse echo ultrasonic inspection…may be accomplished using pulse echo techniques.…
