The influence of W-FSAM process parameters on mechanical properties of 6061 aluminium alloy

Abstract The Wire Friction Stir Additive Manufacturing (W-FSAM) process is an emerging solid-phase friction stir-forming technology that combines friction stir welding technology with additive manufacturing. By generating heat through friction between the stirring head and the substrate, the material reaches a plastic state without reaching its melting point, effectively avoiding problems such as thermal stress, deformation, and uneven microstructure that may occur in traditional melt additive manufacturing. In addition, the characteristic of continuous feeding ensures an uninterrupted additive process, significantly improving production efficiency and ensuring an uninterrupted additive process when constructing large-sized parts. This study uses W-FSAM technology for additive moulding and investigates the effect of changing relevant parameters on the tensile strength of moulded parts.
