I should clarify what I am asking. I want to know if I calibrate my unit using a standard that has a wall thickness less than the parts that I am inspecting will the results of the inspection be inaccurate? Basically my shear wave unit is calibrated using a standard that has a wall thickness of...
When performing a shear wave UT inspection on drill pipe tubes does the wall thickness of the test specimen (calibration standard) have to be the same thickness and diameter of the equipment being evaluated?
