[MW:11096] Clarification for Dissilmilar Weld Radiography Interpretation

Dear All,

 

Code: ASME Sec VIII, Div 1, Ed'09

Ref:    Base Material - SA 516 Gr.70N, 30 thk , Clad Material - Incoloy 825, 3 mm thk

 

Query:

Material 1: Carbon Steel, Material 2: Composit Material(CS+Incoloy), SA 265

How can we have a good judgement on RT Interpretation for Dissmilar Weld joint as density will vary due to different composition?

Do we have Image Quality Indicator for Dissimilar Metal?

 

Hope to see response from all Sections as usual.

 

Thanks & Regards

Vino-Doha
