Infrared Thermography Inspection
Infrared thermography measures heat flux and temperature differences on the surface to detect hidden corrosion. It enables area-wide analysis without contact.
Physical-Chemical Mechanism of Action
Infrared thermography uses the infrared light emitted by all surfaces. Corrosion damage changes the thermal conductivity and absorption of the material surface, leading to distinct temperature patterns.
Metallurgical Relevance & Welding Risks
Hidden corrosion can cause cracks and failure. Infrared thermography detects these damages early before they become visible. This prevents potential failures and increases component safety.
Workshop Practice & Action Guidelines
Use a high-resolution infrared camera with calibrated measurement parameters. Position the camera at a distance of 1.5 to 2 meters from the component. Analyze the temperature differences and correct any corrosion damage by cleaning or welding.
