Efficient non-destructive testing of a wide variety of materials and defect types
Non-destructive testing saves time and costs
Analysis of process immanent temperature differences or externally induced heat streams
Pulsed activation allows the detection of below-surface errors
In-line applications for permanent quality control possible
Sensitive heat measurements to indicate areas of different mechanical stress
Material tests using thermal imaging save time and costs as test objects will not be destroyed during process. They can be used for further testing or locating quality problems that could be corrected. NDT tests with infrared camera systems provide good solutions with greater applications as they can be used for a wide range of different materials and types of defects. A huge advantage is that thermographic testing procedures can be applied to larger areas at once in comparison to ultrasonic or other methods that focus on smaller zones.
Thermography can be used for:
Which method of thermography is used for material testing depends decisively on the question of the origin of the heating of the test object. In one test mode, it could stem directly from heating the test object gains during its production process. This case is referred to as passive thermography. The other possibility is called active heat flow thermography or just active thermography. This is when the test object will be thermally activated by an external energy input for instance by a halogen radiator or a flash lamp.
