You can do any NDT after welding , No issue using oil or couplent,Hydrogen backing at 300 Deg C and above for removal of entrapped hydrogen in the weldment, NDT Carried at atmospheric temperature.
Thanks

Dear experts,
After completion of hydrogen bake out of P91 / P92 welds, Can we do perform UT or MPT?
I mean is there any problem with coup-lent / liquids while performing UT or MPT on P91 / P92 Welds?
Please clarify me?
