Abstract:The mechanical performance of AZ31, a popular aerospace structural material, manufactured using CMT-WAAM was studied in this paper. A wall of 70 × 200 × 4 mm was built by layer-by-layer deposition of 4 mm thick beads. The influence of rolling along the direction of welding on hardness, tensile strength and residual stress was investigated and compared with the control build fabricated using “synergic” parameters recommended by Fronius, Austria. The specimens extracted from the AM (Additive Manufacturing) built… Show more
