Thermal imaging has long been used for discovering, understanding, and interpreting the temperature of objects within our environment. From the advent of thermal imagers in the 1950s to present day – we’ve continued to evolve and discover new applications. Infrared thermography provides a variety of different testing techniques for a wide range of components, machines, and structural materials, allowing trained thermographers to find subsurface anomalies. In this white paper from The Snell Group, learn about the use of thermal imaging for nondesctructive testing (NDT) technologies. This white paper includes an overview, basic theory, and methodologies of thermal nondescructive testing.
