PA/TOFD Inconel Coating

So i have this Inconel weld with buttering and a coating. Any suggestions or special considerations to tackle this with Phased Array/ToFD for 100% coverage?

Kevin, is the so-called buttering actually carbon-manganese steel? Isn’t it more common to butter the carbon steel component with the corrosion resistant alloy? An associate of ours has reported on this process with some nice images and overlays! http://www.aitechnologies.biz/inspection_of_wel…

yeah i think it should be the alloy. I’ve had a look at the article, the response from the PA seems ok, i guess we will just have to make a reference block with known flaws and see what kind of detection we get.
