Study of the use of FSE solid state recycled wires for fusion welding and WAAM process

This study explores the use of wires recycled by FSE using aluminium machining chips as filler metals for gas tungsten arc welding (GTAW). It evaluates the impact of cleaning the machining chips before the FSE process. The results show that cleaning the chips improves wire uniformity and decreases the porosity. This study confirms the potential of using FSE-recycled aluminium wires while emphasizing the importance of chip cleaning and the need to further optimize the process to reduce the porosity of the weld.
