| Abstract Scope |
Wire Arc Additive Manufacturing (WAAM) suffers from dimensional inaccuracies due to variations in bead geometry and layer height accumulation during deposition. In this study, the dimensional accuracy of WAAM-fabricated walls was evaluated by comparing two strategies: a conventional constant layer height and a sensor-assisted deposition. The constant height maintains a fixed increment throughout the build, whereas the sensor-assisted approach adjusts the deposition height based on real-time feedback from monitoring sensors.
Thin wall structures were fabricated using identical welding parameters to isolate the influence of the height control strategy. Measurements along the build direction were obtained using post-process metrology and compared with the programmed geometry. The results indicate that the constant height method leads to cumulative deviation as the build progresses due to variations in bead height and thermal distortion. Comparatively, the sensor-assisted approach reduces layer variations by compensating for deposition irregularities, resulting in improved geometric conformity and reduced height variation. |
