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.

Product Spotlight

Exertus Dual 120

The Exertus Dual 120 Projector has the ability to accept Iridium 192 sources or Selenium 75 source
...
s. This projector incorporates design and safety features that make it flexible, compact and lightweight. The Projector is lighter than most of its competitors. It incorporates an improved source channel, based on a new helicoidal design, which makes maintenance easier. The helicoidal design also allows smoother movement of the source assembly inside the device, making it easier for the operator and improving safety. The Projector also has a unique safety feature not found in competitive products. The source assembly locking mechanism is triggered by the source holder capsule at the front of the source assembly, thereby always assuring the operator that the source has returned to the safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
