UT of Bimetallic Tubing

Does anyone have any recommendations for performing UT of metallurgically bonded bimetallic tubing, where the two layers have differing sound velocities? I need to perform the normal OD and ID defect tests, as well as verify the bond quality.

I see the bond quality as being really interesting, since there should be a good reflection from the interface, so distinguishing from the reflection due to the impedance difference and that due to a lack of bond could be challenging.

I'm also puzzled by handling the angle beam testing, since the sound beam will altered at the interface, going and coming.

Suggestions as to where to go for information are appreciated!

Re: UT of Bimetallic Tubing
What are the materials.

What is the thickness of the tubing?

Using refracted Longitudinal Waves and Creeping Waves, you should be able to handle the interface problems.

Establish a TOF (Sound Path) and depth calibration using ID and OD notches.

You can contact GE Inspection Technologies Application center to find out the solution for that. More detail visit www.GeinspectionTechnologies.com
