Regarding to Radiographic Testing (RT) of weld
1) Does any codes / stands mentioned how to selection of film type/class like carbon steel and stainless steel?
2) On the heavy wall thickness plat 70 mm (Sphere Tank) welded by SMAW testing by PAUT were found a lot of defects but re-test by RT Ir-192 doesn't found any things, Any opinions to recommend
Thanks and Best Regards

Hi
I believe it's due to non concentric flux coating of electrodes. It's a manufacturing defect.
Take few electrodes from the pocket inspect visually and measure it's flux coating thickness through vernier caliper and you will find uninformed coating.
