Re: UT wave velocity measurement
Any ultrasonic thickness gage or flaw detector can be used to measure sound velocity. Some instruments (like the Panametrics-NDT 35 series gages from Olympus NDT) offer direct readout of sound velocity based on an entered material thickness. For any other instrument, simply do a velocity calibration based on a material sample of known thickness and read the result.

Hydrogen embrittlement is commonly identified through a decrease in sound velocity across a known metal path. It is also associated with an increase in attenuation and scatter noise.
