Abstract Scope |
This study introduces a closed-loop control system for Contact Tip to Work Distance (CTWD) and interpass temperature in Wire Arc Additive Manufacturing (WAAM), aimed at enhancing the production of architectural facades. By integrating feedback from laser-profiled measurements and thermographic cameras, the system dynamically adjusts CTWD and temperature settings, addressing the challenges of inconsistency in layer deposition and thermal accumulation. The implementation of this system enabled the automated manufacturing of aluminum mullion with a height of 855mm. Trials confirmed the system’s ability to maintain consistent layer quality and thickness distribution, while effectively preventing defects such as voids. The results demonstrate that precise control of CTWD and interpass temperature is crucial for optimizing the quality and reproducibility of WAAM components, making it a valuable advancement for the construction industry in customizing large-scale metal structures. |
