Thermographic
Testing
Heat is applied evenly to the surface of a component. As it cools, the
component emits energy of various wavelengths. Variations in the cooling
of different regions of the component are detected and measured with
an infrared camara. The camara is connected to a computer, which converts
the reading into a thermal image. Defects in the component can be detected
from the variatons shown on the thermograph.
