Re: [MW:22893] Excess penetration measurment in Radiograph

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.
