Thermal imaging can be used for quality control in many industries. It is a nondestructive inspection method, which is especially used to detect flaws that are not visible on the surface. These days the main industrial task for thermal imaging systems is to monitor the temperature of industrial facilities. Thanks to the development of powerful sensors this technique is gaining in significance for quality control.
One inspection method is the heat flow thermal imaging, which can make invisible flaws visible. Because each material has different heat conductivity, invisible flaws below the surface in component parts can be detected. The infrared thermal imaging is only one example of many. The result of the heat flow thermal imaging can be directly implemented in the rejection of a faulty product.
