Non-Destructive Quality Control of Metallic Components<\/h3>\n\n\n\n

The metallic microstructure plays a key role in the mechanical properties of components. Surface hardening reduces wear and thus extends service life, for example at shaft bearing locations in engines, generators, or rail wheels. State-of-the-art quality assurance is currently performed only statistically through microscopic examination of drawn and fractured specimens. However, there is a great need for a non-destructive, inline-capable inspection method, since sampling is not always possible and 100-percent inspection is necessary for continuous quality improvement. <\/p>\n<\/div>\n<\/div>

AI-Assisted Analysis of Laser Ultrasound<\/h3>\n\n\n\n

Laser ultrasound has already shown great potential for measuring the depth of hardening in some steels. However, conventional signal analysis\u2014such as averaging and filtering\u2014has limited capabilities, as it provides little additional information from the apparent noise in the ultrasound signals. AI models are expected to interpret the ultrasonic data significantly better after a training phase. Advanced methods for feature engineering and machine learning are used, including regression, classification, and anomaly detection models for time-series analysis, as well as deep learning approaches for image data analysis. <\/p>\n<\/div>\n<\/div>

Approaches to Annotation<\/h3>\n\n\n\n

To address the bottleneck in annotation, the project is pursuing several approaches: research into a semi-automated framework that enables domain experts to annotate laser ultrasound data; the combination of ML approaches with correlative data from microscopy; and the use of simulated data, in which the ground truth is generated alongside the data. In this way, IQMet combines the strengths of non-destructive testing with advanced data analysis techniques for fast and accurate microstructural analysis. <\/p>\n<\/div>\n<\/div>
