UT for disbonding

we have the task to test for disbonding of SS 1.4550 using SAS4IG (nearly similar material) as weld metal. The thickness of weld metal is appr. 3 mm. Testing should be performed using SDH as reflectors. the test block has a diameter of 273 mm (not ready yet). The test object is ready next Monday.
I prepared a MSEB4, E series, to be adapted at the curvature of 273 mm.
But now I am not sure if it is the right probe. Should`nt I use higher frequencies?
For any hints or advices I thank You in advance

The best probes for disbonding detection are the benchjmark and between 10-15 MHz because you you need haigh resolution for diferentiate the metal base and the SS interface

Thank you in advance
