Dear Ilyas,
Thanks for the feedback. Is RVI referring to radiographic visual inspection?

Hi
Try PAUT CM or RVI if accessible to monitor root oxidation.

Dear all,
Please advise optimum method to detect corrosion internal corrosion at weld joint (for carbon steel, stainless steel SS 316L and duplex stainless steel – UNS 31803
1. Is angle UT flaw detector is adequate measure internal corrosion with good probability of detection (POD)? Is angle UT flaw detector similar to UT Shear wave?
2. I would expect a screening NDT method, if there is some evidence of internal corrosion from screening NDT method , then go for detail NDT to assess the extent of the internal corrosion. What are these NDT methods?
