The Soldamatic AR Welding Simulator is an augmented-reality training system designed to support experimentation, validation, and deployment of digital welding training processes in a safe and controlled environment. It replicates real welding equipment, including the torch, helmet, and workpiece, within a simulated environment, enabling realistic training without the need for physical consumables. The system provides real-time feedback and supports the development of welding skills and muscle memory through interactive training scenarios. It enables efficient and cost-effective training while reducing material usage and operational risks. The TestBed offers an accessible environment for training, performance assessment, and Proof-of-Concept activities in digital welding and immersive learning technologies. It supports DeepTech applications in augmented reality and digital manufacturing, and aligns with Industry 5.0 principles by enabling safe, human-centred skill development.
