Sustainable Utilization and Recycling of Gases in Welding and Additive Manufacturing

Welding and welding-based additive manufacturing (AM) are essential in numerous industrial applications, including aerospace, automotive, and construction. In most of these processes, shielding gases such as a mixture of argon (Ar) and carbon dioxide (CO2) are used, primarily to protect molten metal from oxidation during deposition.
Centered on the concept of circularity, this project aims to conduct a comprehensive feasibility study to explore the potential for recycling and reusing shielding gases, particularly argon and carbon dioxide, post- welding and AM. The study will set the foundation for future initiatives, aiming to enhance environmental sustainability and process efficiency while reducing overall gas consumption.
