Abstract
Extended reality (XR) technology has been proven an effective human–computer interaction tool to increase the perception of presence. The purpose of this study is to develop an interactive XR-based welding tutorial system to enhance the learning and hands-on skills of novice welders. This study is comprised of two parts: (1) fundamental manual metal arc welding (MMAW) science and technology tutoring in a virtual reality (VR)-based environment, and (2) hands-on welding training in a mixed reality (MR)-based environment. Using the developed tutorial system, complicated welding process and the effects of welding process parameters on weld bead geometry can be clearly observed and comprehended by using a 3D interactive user interface. Visual aids and quantitative guidance are displayed in real time to guide novice welders through the correct welding procedure and help them to maintain a proper welding position. A user study was conducted to evaluate the learnability, workload, and usability of the system. Results show that users obtained significantly better performance by using the XR-based welding tutorial system, compared to those who were trained using the conventional classroom training method. ? 2022, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature.
