Fabricação aditiva por arco submerso

The proposed research addresses critical challenges in modern manufacturing. One key challenge is the demand for large-scale metallic components with minimal defects, nearly homogeneous microstructure, and improved mechanical properties. Traditional manufacturing methods struggle to meet these requirements efficiently. Additionally, the scarcity of exploration in additive manufacturing (AM) utilizing submerged arc welding (SAW) as the heat source presents a significant challenge. The initiative aims to fill this gap by developing a setup capable of producing such components, thereby addressing pressing needs in various manufacturing industries. Furthermore, the project focuses on advancing AM technologies, particularly submerged arc additive manufacturing (SAAM), to provide cost-effective solutions for custom-made fabrication. By leveraging SAAM's high deposition rate and hybridization with other arc-based heat sources, the project seeks to overcome limitations in current manufacturing processes, thereby addressing supply chain challenges and enhancing operational efficiency across industrial applications. The objectives associated to this project are ambitious and go beyond the state of the art in several ways. Firstly, the initiative aims to push the boundaries of arc-based AM by utilizing the SAW process, which has seen limited exploration in AM thus far. This novel approach offers high potential uptake by multiple industries but remains largely unexplored. Secondly, the project seeks to establish advanced thermodynamic and thermomechanical simulation frameworks to precisely control microstructures and mechanical properties at specific locations, a capability not commonly found in current manufacturing processes. This is further compounded by the use of in-line processing control which will provide the backbone for full microstructure and property control during SAAM, this being an excellent way to accelerate industrial deployment in the near future. Moreover, the project's focus on developing innovative tools tailored for sustainable fabrication and repair of large metallic components aligns with the sustainable development objectives outlined in Goals #9 and #12 of the 2030 Agenda. By prioritizing these objectives, the project aims to mitigate the carbon footprint linked to energy-intensive industries, thereby driving innovation and competitiveness in the global manufacturing landscape. Additionally, the project's commitment to advanced training of young researchers, dissemination of findings through high-impact publications and dedicated project websites, and engagement with industry stakeholders through workshops underscores its ambition to foster collaboration, knowledge dissemination, and skill development in the field of additive manufacturing.
