PAUT in Inconel cladding

Hai Experts,
Is PAUT possible for the following joints..

1)Volumetric examination and bond line integrity check in cladded area.

cladded Pipe OD/Material=24"/ API 5L X65
Cladding material & thickness=Inconel 625 & 4.3 mm thickness.
Is there any special Probe like DMA or DLA required?

2)Volumetric Examination in butt joint/similar welds

Butt joint= similar welds ,single 'V' between cladded pipe and cladded hanger flange.

If the weld is CS, you can use PAUT - shear wave but limited to the 1/2 vee mode. So that will mean removal of weld cap to get full weld coverage. And since it is CS you can add TOFD
