SKILL TRAINING SYSTEM OF MANUAL ARC WELDING BY MEANS OF FACE-SHIELD-LIKE HMD AND VIRTUAL ELECTRODE

摘要

We propose a training system of manual arc welding by means of Mixed Reality technique. The system consists of a face-shield-like Head Mounted Display (HMD) and a virtual electrode unit. The former unit is a video-see-through HMD having almost the same shape and size as an actual face shield. Mixed image of real environmental scene and virtual objects (arc, spatter, etc.) is displayed onto the LCD in the HMD. Moreover, a training assistant function is implemented. As a result, it is confirmed the system is effective in training novice welders.
