About
Stewart Williams is a leading researcher in advanced manufacturing, specializing in Wire + Arc Additive Manufacturing (WAAM) and in-process non-destructive evaluation (NDE). His work sits at the intersection of robotic manufacturing, materials science, and quality assurance, addressing one of the most pressing challenges in modern industry: producing large-scale, high-integrity metal components efficiently and reliably. Williams has made foundational contributions to WAAM technology, establishing design rules and build orientation strategies that have become reference points for the field — reflected in his most-cited paper accumulating 148 citations since 2017. His research extends beyond fabrication itself, pioneering integrated inspection methodologies that embed ultrasonic phased array and eddy-current NDE directly into the manufacturing process, enabling real-time defect detection layer by layer. This in-process quality assurance approach represents a significant step toward autonomous, certification-ready additive manufacturing. His work on mechanical property enhancement through machine hammer peening and robotic motion error compensation further demonstrates a holistic approach to manufacturing excellence. With publications spanning robotic systems, sensor development, and collaborative manufacturing architectures, Williams has accumulated over 400 citations, establishing himself as an influential voice shaping the future of large-scale metal additive manufacturing.
