Digital Visual Inspection in the Welding Industry – Winteria®
Through extensive research involving advanced numerical methods, experimental validation, and collaboration with Swerea KIMAB and leading industrial partners, KTH developed Winteria®—an innovative system that provides precise digital assessment of weld geometry and quality. Today, Winteria® is successfully integrated into industrial production lines, significantly improving weld quality, reducing structural weight, and increasing the durability of welded components and structures.
Background
The structural integrity and durability of welded components greatly depend on the precision of weld quality, especially when utilizing advanced high-strength steels to achieve significant weight reductions. Conventional weld inspection methods typically rely on manual gauges and visual inspection, which lack the precision and consistency required for modern manufacturing processes. Addressing these limitations required advanced automated and digitized solutions capable of objective and accurate geometry measurements and evaluations.
Project Aim
The aim of the project was to develop and commercialize a sophisticated inline digital inspection system. The system combines laser-based measurement technology with automated numerical evaluation algorithms to rapidly and accurately assess weld geometry and quality. These innovations allow real-time monitoring and quality assurance directly on production lines, ensuring compliance with stringent industry standards and specifications.
Industry Impact and Recognition
Since the establishment of Winteria AB in 2017, supported by KTH Innovation, STING incubator, and Vinnova funding, Winteria® has transformed industrial weld inspection processes. Major manufacturers such as Volvo Construction Equipment and HIAB Cargotec, SSAB , etc. have adopted the system, setting new international corporate standards for weld quality. Implementation has resulted in substantial reductions in material usage and component weight, significantly enhancing safety, reliability, and environmental sustainability in manufacturing. The innovation has gained significant industry acclaim, notably winning the University Challenge in 2015, Swedbank Innovation
