Ultrasonic thickness gauges can be used to measure the wall dimensions of hollow castings. Today, microprocessor-based instruments using ultrasonic sound waves can accurately provide much more information about the hidden internal structure of both ferrous and nonferrous castings. In the past, a foundry worker would estimate the quality of a casting by tapping it with a hammer to evaluate the sound of the ring. The art of casting metal into specific shapes has been practiced for thousands of years but only in recent decades have modern ultrasonic NDT tools been available to help ensure product integrity. This application note provides a general overview of ultrasonic nondestructive testing applications in the foundry industry, including thickness gauging, flaw detection, and nodularity testing.
