Up Topic Welding Industry / Inspection & Qualification / UT of 317LMN joints Welded With NiCrMo-xx

Is it possible to perform the above UT with a typical UT operator and equipment or are there special techniques that will need to be followed to do this ?

Our material is only 1/4" thick. UT is Per ASME. I am more interested in the ability to detect discontinuities than code requirements.

Thanks

it can be done, but you will need to fabricate a calibration block out of the same type of materail. sound velosities are different in each type of metal, as are attinuation (loss of sound amplitude). i don't have a code in front of me but i believe it is figure j-18 in asme
