UT testing

I'm looking for UT methods testing thin aluminum layer (1mm) with corrosion defects from the bottom. This is typical in multilayer structure. Can You suggest me some methods (including some propositions parameters configurations). I'm working with automated scannig system.

You might be better off working with an eddy current approach. I used this method on thin-skinned aluminum-to-wood shelters with corrosion on the bonded interface.

I agree with Mr. Rodgers. With properly designed probes Eddy Current can be used to assess even the layers below the first layer. As well, ECT is easily automated.
