| Abstract Scope |
Advancements in numerical and analytical modeling of heat transfer in wire arc additive manufacturing (WAAM) have led to improved agreement between simulated and experimental temperature results. Additionally, thermo-mechanical models of the WAAM process have been developed for improved prediction of residual stress, distortion, and resulting microstructure. However, implementation of thermal modeling into path planning for WAAM to influence resulting temperature distribution remains a topic for further investigation and development. Temperature distributions of part surfaces were measured during WAAM of four parts. Although designed from a constant part model, a unique and traditional deposition trajectory was used to manufacture each part. From the temperature distributions, metrics relevant to residual stress, grain size, and grain morphology were calculated and are discussed. The experimentally acquired temperature distribution measurements will be compared to temperature distributions from new deposition strategies in future work. |
