I have to inspect 132mm thickness SAW welding, CrMoV material
according API 934 for reheating cracks using TOFD.
If I didnt get wrong, I have to calibrate the system in the ASME Block
with the SDH and then adjust the gain on API block with the notches,
right??
Another doubt is about the crack characterization... its commom to
detect some porosity, even on transversal scanning, how we will judge
some signal to be reheating crack?
Thanks for the help.
Paulo
