Integration of advanced experiments, computation and data for Duplex Stainless Steel joining innovation

Project description

Integrated Development of Welding and Joining Techniques of Advanced Stainless Steels

Materials data led research for welding and joining of advanced alloys is of significant technological and economic benefits. Duplex stainless steel and welded structures of similar or dissimilar materials are widely used due to their good corrosion resistance and mechanical properties. Funded by the MSCA programme, the i-Weld project aims to develop and integrate advanced experiments, computer-aided manufacturing and physical modelling for welding process improvement and performance enhancement. Researchers will develop in-depth data of the structure, phase, defects in different welding zones and processes, and improve the properties through compositions and structures design at different scales. The data will serve as a pivoting framework for future research and innovation, speeding up the material or product development cycle.


The proposed project aims to collaboratively research on welding of duplex stainless steel (DSS) through modern data system/sharing, experiments and predictive physical modelling for developing new materials and processing regimes. The project will establish a systematic data system for the key physical structure/phases relative to the welding and corrosion of DSS. The project will establish the optimum welding regimes for enhanced mechanical and corrosion performance with the aids of hybrid computer aid design and manufacturing (CAD/CAM) and physical based material modelling. The data and advanced approach will be used to develop new disruptive manufacturing technology to control the structure, phase and defects in the welding in particularly the heat affected zones (HAZ), which is the most critical/limiting issue for manufacturing and applications of DSS and other material systems. The work will jointly explore the use of modern data and predictive modelling technology in developing dissimilar/hybrid material systems for more significant weight/cost reduction. The resulted advanced data system, new materials, welding process and hybrid lightweight materials will contribute the research and innovation capacity in Europe and the world on DSS, stainless steels and associated systems with a long term economic and social impact (e.g. health, environments and society). The advanced data system will serve as a pivoting platform for future research and innovation, speeding up material or product development cycle, with fundamental contribution to academic and industrial R&D. It will enhance the R&I capacity of inter/multidisciplinary intersectoral partners, and jointly developing major break-through technologies. The work combined several novel approaches I R&D, will contribute the development of Industry 4.0 for welding and significantly accelerate the development of the Research skills, knowledge and career of the ECR with lasting impact in the EU and beyond.
