| Abstract Scope |
This work aims to establish a credible manufacturing path for full-size pressure vessels using wire-arc additive manufacturing (WAAM). A typical vessel is 3–5 m in diameter and ~10 m tall. The central challenge is scaling WAAM from subscale demonstrations to full-scale production. The first step is to manufacture a 2500lb component to better capture scale-driven effects that are not linear with small part sizes. Key challenges include increased deposition times, robotic reach, kinematic limits, and multi-agent coordination (MedUSA), severe dome overhangs requiring non-gravity-aligned deposition with improved closed-loop control, high fluidity 316LSi behavior, and amplified thermal gradients, residual stress, and distortion. This work will present a phased approach starting with a sub 500lb demonstration, overhang-focused builds, leading to an integrated ~2500lb component. |
