Yes, I agree with your Radiography
image, but ASME B 31.3 acceptance criteria is only for
Visual Inspection not forRadiography image,
moreover ball passing test is not specified in ASME
standard,
Any idea
about  Image Contrast graph method, Shell DEP has specified
this test procedure for measuring Excess penetration,

Hi,
My opinion, in DWSI
superimpose, you can see the excess penetration clearly.
Please refer the attached image.
Please refer table 341.3.2 for
acceptance criteria. However as Mr. Jerald mentioned earlier
you can go for ball passing test to confirm the
ID.
