We propose a training system of manual arc welding by means of Mixed Reality technique. The system consists of a face-shield-like 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. The latter unit consists of a virtual electrode, a motor for adjusting electrode extension length, an electromagnet, and a reflection-type photo sensor. Moreover, a training assistant function is implemented in which inclination angle, feed rate of the virtual electrode, and so on during training are recorded, and their differences between novice and skilled welders are displayed. It is confirmed the system is effective in training novice welders.
