Technology Day: Thermography
Induction thermography is a powerful method for the non-destructive detection of surface defects in metals. Targeted inductive heating creates localized temperature variations at defect sites, which can be visualized and analyzed using infrared cameras.
The FOERSTER Technology Day “Thermography” introduces the physical principles of this inspection method and demonstrates, using real industrial applications, how thermal signatures are generated, which factors influence signal formation and how thermographic inspection results can be reliably interpreted.
Registration deadline: 15 August 2026
Request trainingHow do surface defects become visible through heat? The Thermography Technology Day explains how thermal signatures are generated and how induction thermography is used in the industrial inspection of semi-finished products and components.
Goal of the Technology Day
The goal of this technology day is to provide a solid understanding of the physical principles of induction thermography and the generation and interpretation of thermal inspection signals. Participants will learn how eddy currents create local temperature distributions, how surface defects influence thermal signatures and how these signals can be reliably evaluated in practical inspection scenarios.
Target Audience
This Technology Day “Thermography” is aimed at inspection engineers, quality managers, operators and technical decision-makers who want to build a deeper understanding of thermographic inspection methods or expand their knowledge of modern techniques for surface defect detection.
