Thermal techniques of nondestructive evaluation (NDE) have become mature high-technology fields that have essentially contributed to nondestructive testing, condition monitoring, and predictive maintenance. In many industrial applications, these techniques help to identify problems that must be addressed, prevent equipment failure, and provide significant cost savings.

Thermal NDE has many advantages including a wide range of applications and a much higher inspection rate than other NDE methods. Improvements in IR imagers in the last decade, accompanied by dramatic advances in computer data processing, have resulted in significant improvements in the detection and characterization of hidden structural defects in solids by analyzing material surface temperature distributions.

This chapter establishes the physical basics of thermal NDE including elements of heat conduction in solids with defects and basics of thermal radiation, as well as inspection terminology, procedures, and data processing. Following ISO 10878, this inspection technique is called Infrared Thermographic Testing (ITT). In the chapter, the elements of thermal NDE are discussed at a level which is necessary for understanding the physical principles of this testing method.
