Crack Inspection

Cracks are among the most critical defects in metallic materials and components. They can significantly reduce mechanical strength, fatigue life and operational safety, often leading to premature failure if left undetected. FOERSTER inspection systems enable reliable, non-destructive crack detection across a wide range of materials, product geometries and manufacturing processes, supporting consistent quality from production to maintenance.

Cracks can develop at various stages of the manufacturing process, including rolling, drawing, forming, welding, heat treatment and machining. Depending on the application, they may appear as longitudinal, transverse or oblique discontinuities and often remain invisible to the naked eye. Even the smallest surface-breaking crack can act as the starting point for fatigue failure under cyclic loading, making early detection essential for ensuring product quality, operational reliability and compliance with industry standards.

FOERSTER offers advanced inspection solutions for detecting cracks on bars, tubes, wire, billets and finished components. Depending on the material and inspection task, technologies such as eddy current testing, magnetic flux leakage and induction thermography provide highly sensitive and repeatable crack detection, even at high production speeds or on complex component geometries. Automated inline inspection systems enable continuous quality control directly within the production process, while portable testing instruments support reliable inspections during maintenance, repair and quality assurance.

With decades of expertise in electromagnetic and thermographic testing, a comprehensive portfolio of sensors and inspection systems, and application-specific solutions tailored to different industries, FOERSTER helps manufacturers detect critical cracks at the earliest possible stage. The result is improved product quality, reduced scrap, increased process reliability and greater confidence in the integrity of every tested component.
