Nondestructive Testing of thin bars

Does anybody has experience of doing real thin wall cylinders. AMS standard does talk about calibration standard for bars as thin as 0.125 inches and smaller. How difficult is is to inspect these thin bars using ultrasonics(can be automated tactic). What if we compare Ultrasonic testing with Eddy current testing for thin material( eddy current density is zero at center).

Re: Nondestructive Testing of thin bars Innerspec Technologies www.innerspec.com has developed a technique for inspection of thin bars using ultrasonic EMAT. It is non-contact like EC but provides the penetration of ultrasound.

Re: Nondestructive Testing of thin bars We regularly look at steel and aluminium plates down to about 0.1mm thickness, and can provide equipment to do it on request. The trick (when using ultrasound, which is what we do) is to use resonance rather than time-of-flight at these thicknesses.
