The ITvis ACD system offers an advanced solution for automated crack detection, particularly designed for hardening cracks in forged components. Available in both semi-automated and fully automated configurations, the system allows for component feeding either via conveyors or manually, depending on the test stand setup. Leveraging machine learning algorithms, the system ensures automated, user-independent evaluation of test results. The process achieves remarkable speed, with inspections completed in less than 0.1 seconds, seamlessly integrating into existing production cycles. Its robustness against material and environmental variations surpasses traditional methods like eddy current inspection, ensuring a low pseudo-rejection rate. Induction thermography forms the foundation of ITvis ACD, offering non-destructive, non-contact evaluations ideal for both production and maintenance environments, often replacing conventional magnetic particle inspection for enhanced cost-efficiency.

This automated inspection system uses lockin thermography for inline testing, focusing on detecting and evaluating the quality of adhesive bonds, particularly in fiber composite structures. The technique helps ensure the structural integrity by analyzing the heat flow on object surfaces using halogen lamps. The heat flow is captured by infrared cameras, allowing for identification of thermal signatures caused by defects or variations in material thickness. The lockin thermography method boasts high sensitivity due to its sinusoidal modulation of lamp intensity and Fourier transformation analysis of the resulting phase and amplitude images. This system is versatile, applicable to a stationary or continuous motion process, and is also available as a laboratory system. It's particularly effective in detecting delaminations, dry spots, resin accumulations, and coating issues, making it essential for maintaining the reliability and performance of complex adhesive bonds.

Optically excited lockin thermography is a sophisticated non-contact, non-destructive testing technology optimized for analyzing fiber-reinforced plastics (CFRP) in both aerospace and automotive sectors. This technique is particularly advantageous in scenarios demanding rapid assessment of large, geometrically complex areas. It operates effectively under diverse environmental conditions, making it suitable for both production and maintenance workflows. By employing sinusoidal modulation of halogen lamp intensity, the system facilitates precise heat flow analysis. This modulation results in phase and amplitude images that are produced from captured infrared sequences via Fourier transformation, significantly enhancing defect detection by reducing interference from varied emission coefficients or inhomogeneous excitation. The method is seamlessly expandable with edevis’ suite of excitation sources and software. Typical applications include evaluating impact damages, delaminations, and variations in material thickness, providing critical insights into the structural integrity of components.
