Surface Defect Detection

Surface Defect Detection

Surface defects such as pores, notches, grinding burns, localized material discontinuities and near-surface inclusions can significantly affect the quality, performance and service life of metallic products. FOERSTER inspection systems enable reliable, non-destructive detection of surface and near-surface defects, helping manufacturers maintain consistent product quality throughout the production process.

Surface defects can be introduced during rolling, drawing, machining, grinding, heat treatment and other manufacturing processes. While often invisible to the naked eye, these imperfections may reduce fatigue strength, impair functionality or compromise dimensional accuracy. Early detection helps reduce scrap, optimize production processes and ensure consistent product quality.

FOERSTER provides advanced inspection solutions for detecting a broad range of surface and near-surface defects, including pores, notches, grinding burns and localized material discontinuities. Depending on the application, technologies such as eddy current testing, magnetic flux leakage and induction thermography deliver highly sensitive, repeatable inspection results across a wide range of materials, geometries and production environments. From fully automated inline systems to portable inspection devices, FOERSTER combines innovative sensor technology with decades of application expertise to ensure reliable defect detection throughout the manufacturing process.
