From Arc to Additive: Rethinking Energy and Material Flow in Metal Processing

This project explores the thermal sources and energy flow mechanisms that govern heterogeneous welding and metal additive manufacturing, two processes where matter and heat intertwine to shape the future of fabrication.

By modeling mass transfer, thermal gradients, and hydrodynamic behavior during TIG welding and additive fusion, the study aims to decode how energy transforms, dissipates, and ultimately determines the integrity of the final structure. The research also investigates friction stir-based processes (FSW, FSSW, UFSW) to develop a unified description of thermal sources adaptable to diverse joining conditions.

Through advanced simulation and experimental validation, this work seeks to bridge the gap between energy efficiency and manufacturing precision, revealing how mastering heat itself could redefine the boundaries of modern metallurgy
