[MW:3081] Re: Regarding the NDT to be carried out for 60 mm thick austenitic stainless steel plates

1. Both RT and UT Combination will be best. For surface PT is mandatory.
2. UT we can use Shear wave(SW) for fusion zone, Volumetric can use Angle beam  Longitudinal wave(LW) (Single crystal for higher beam distance and Twin for Near zone)
3. Always better to reconfirm with LW probe wherever SW indication, because shear wave redirect.
4. Using LW for fusion zone probably higer sensitivity (More than code requirment)

Hi,
If your specification permits for RT or UT you can carry out any of these test for 60 mm Thick S.S.
For RT you may need cobalt 60 or High strength iridium 192.
For Ultrasonic Testing you shall use the RTD Twin crystal longitudinal wave Angle probes.

Nilesh Pathare.
