: I am looking for a reliable way to UT thin gauge, under 5/16", steel tube that has a circumferential joint joined utilizing a backing bar.

I'm not sure I'm properly visualizing what you're doing, but if it's a brazed or welded joint, we may be able to do something with small diameter, sharply focussed immersion transducers and appropriate fixturing. The tube diameter itself is not a problem. If it's just mechanically clamped, on the other hand, it's not a good application for ultrasonic flaw detection.

I'd be happy to look at a drawing if you can send one.
