Ultrasonic Testing (UT)
Detect surface breaking, internal imperfections and measure material thickness.
Ultrasonic Testing (UT) uses high frequency ultrasonic waves to detect surface breaking and internal imperfections, measure material thickness and determine acceptance or rejection of a test object based on a reference code or standard. UT is completely nondestructive. The test piece does not have to be cut, sectioned, or exposed to damaging chemicals. Access to only one side is required.
A wide variety of cracks, voids, disbonds, inclusions, and similar problems that affect structural integrity can all be located and measured with UT methods. Test results are highly repeatable and reliable. The minimum detectable flaw size in a given application will depend on the type of material being tested and the type of flaw under consideration.
