Ultrasonic Testing (UT)

Ultrasonic Testing utilizes high frequency energy introduced into a part. The sound energy can be used to determine the material thickness. UT also can detect and evaluates a flaw in a part giving the operator dimensions and orientation of that flaw. Since the 1940s, the laws of physics that govern the propagation of sound waves through solid materials have been used to detect hidden cracks, voids, porosity, and other internal discontinuities in metals, composites, plastics, and ceramics. High frequency sound waves reflect from flaws in predictable ways, producing echo patterns that can be displayed and recorded by portable instruments. Ultrasonic testing is completely nondestructive and safe, and it is an established test method in many basic manufacturing, process, and service industries, especially in applications involving welds and structural metals.

Many people are familiar with the medical applications of ultrasonic imaging, in which high frequency sound waves are used to create highly detailed cross-sectional pictures of internal organs. Medical sonograms are commonly made with multi-element transducers known as phased arrays. The application of ultrasonic phased array technology is not limited to medical diagnosis. In recent years, phased array systems have seen increasing use in industrial settings to provide new levels of visualization in common ultrasonic tests that include weld inspection, bond testing, thickness profiling, and in-service crack detection and sizing.
