| Abstract Scope |
Wire arc additive manufacturing (WAAM) is a process where electrical arc welding is used to produce near-net shapes. Due to the mechanics of the deposition, defects and anisotropy can be induced by the process related thermal cycles. The use of an additive-subtractive hybrid wire arc additive manufacturing (HWAAM) system combines simultaneous additive deposition with subtractive CNC, resulting in faster cooling, greater control of dimensional accuracy, and reduces the need for post-processing. The combination of these leads to interactions between the individual process parameters for each operation and impart complex thermal histories, leading to variations in microstructures and mechanical properties as compared to WAAM. By producing samples of ER70S-6 under varying conditions, the effects of machining and forced cooling on the microstructure and mechanical properties can be assessed. Materials were tested in tension and fatigue, analyzing differences in mechanical behavior to link them to microstructural differences induced by variations in manufacturing. |
