Thermographic Inspection works by using a thermal imaging camera or an infrared (IR) camera to capture the heat emitted or transmitted by a material or component. The camera detects the heat radiation, converts it into a visual image, and displays it on a screen. The thermal patterns displayed on the image are then analyzed by a trained inspector to identify any abnormal thermal signatures that may indicate the presence of defects or abnormalities in the material or component. Thermographic Inspection can be performed in real-time or with post-processing of the captured images, and it can be used on a wide range of materials and components, making it a valuable NDT technique for various industries such as mining, aerospace, electrical, and building inspection.
