An Introduction to Ultrasonic Thickness Gaging
Ultrasonic thickness gaging is a widely used nondestructive test technique for measuring the thickness of a material from one side. Just about anything made out of metal, plastic, composite, ceramic, glass, fiberglass, or rubber can be
measured with easy-to-use, hand-held instruments. This paper provides a brief introduction to the theory and practice of ultrasonic thickness gaging. Read more>>
An Introduction to Ultrasonic Flaw Detection
Of all the applications of industrial ultrasonic testing, flaw detection is the oldest and the most common. 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. This paper provides a brief introduction to the theory and practice of ultrasonic flaw detection. Read more>>
An Introduction to Ultrasonic Phased Array Technology
Ultrasonic phased array systems similar to those used for medical imaging are finding increasing use in industrial settings, providing new levels of information and visualization. Applications include weld inspection, bond testing, thickness
profiling, and in-service crack detection. This paper provides a brief introduction to how phased array systems work and how they can be employed in industrial ultrasonic nondestructive testing. Read

An Introduction to Ultrasonic Material Analysis
Ultrasonic testing can be applied to a wide variety of material analysis applications. Changes in parameters associated with the passage of a high frequency sound wave through a material can often be correlated with changes in physical
properties such as hardness, elastic modulus, density, homogeneity, or grain structure. This paper provides a brief introduction to the theory and practice of ultrasonic material analysis. Read more>>
