Abstract: Wire Arc Additive Manufacturing (WAAM) enables the fabrication of large-scale metallic components with a high deposition rate (2-3 kg/hr) [1]. However, this additive process can be susceptible to thermal accumulation which can negatively affect geometrical and mechanical characteristics. This study investigates the influence of two temperature control strategies: fixed dwell time and interpass temperature control (200 ℃ threshold), during the development of ER70S-6 thin-walled structures using the WAAM-Cold Metal Transfer (CMT) process. Mechanical and microstructural analysis were conducted. Comparatively, the interpass temperature control strategy increased the mean ultimate tensile strength by 13.42% against fixed dwell-time, while producing an improved homogenous microstructure and therefore reducing the variation within the deposition. These findings demonstrate the importance of thermal management in enhancing WAAM component quality and consistency.
