Temperature Correction Formula
(OP)
Can anyone tell me the formula used to manually correct ultrasonic thickness measurements for elevated temperatures ?

RE: Temperature Correction Formula
According to Krautkramer - Ultrasonic Testing of Materials pg 14, the longitudinal velocity (which is applicable to thickness gages) decreases with a temperature increase by about 1 m/s per degree C on average up to 1200 C. Using the nominal longitudinal velocity for steel of 5,900 m/s; the thickness reading would be in error (thicker than actual) by .0169% for each degree C the test piece is above the calibration standard.
