Wire arc additive manufacturing (WAAM) is a flexible and high deposition rate technique for production of a wide range of components. Limited available composition of feedstock (wires) inhibits experimentation aimed at production of high strength parts, particularly for aluminum alloys. In this work, alloy 6061 wires were produced by friction extrusion and subsequently used as the feedstock in a Gas Tungsten Arc additive process. Deposits as thick as 15 mm were evaluated in terms of microstructure, defect content, and strength (via sub-scale tensile testing). Strength and hardness were evaluated both before and after post build aging treatments.
