| Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) processes have a reputation for high material deposition rates, but the time taken to fully fabricate a part is significantly limited by heat buildup during the manufacturing process. The heat from the welding process can build up in parts produced through WAAM if sufficient methods for cooling are not utilized. Ignoring heat buildup can lead to inconsistent and often undesirable material properties. In contrast, allowing for a part to naturally cool between deposition layers may result in higher quality material deposition, but may come at a significant cost regarding time. To reduce total fabrication time while also accounting for heat accumulation, an adaptive approach is being developed in which welding parameters are modified in response to interpass temperature to reduce the time spent on cooling while also attempting to maintain high quality deposition. |
