| 内容記述 | Welding training has some disadvantages such as long time required and need for a considerable quantity of training material; in addition, it is dangerous for beginners. To overcome these limitations, a welding training system using virtual reality can be used to teach appropriate tool movements. However, most trainees may not perform appropriate welding even if they understand the appropriate tool movements. Therefore, teaching appropriate movements of the arm can be more effective than teaching the appropriate movements of the tools. The goal of this study was to produce an effective welding simulator to teach appropriate arm movements. This paper discusses measurements of a welder’s behavior. The angle of each joint of the welder’s arm, including the shoulder, elbow, and wrist, was measured using bend sensors. Electromyography (EMG) sensors were used to perform surface electromyography on a welder’s arm. Six sensor electrodes were placed on two muscles of the upper arm and four muscles of the forearm. A workpiece clamper with charge-coupled device cameras measured the three-dimensional coordinates of each electrode tip. A three-dimensional surface measuring instrument measured the shape of the welding bead. The welding tasks of three professional welders and four beginners were measured. The differences between the movements of a professional’s arm and those of a beginner’s were found. This showed that the beginners moved their elbow and shoulder, whereas the professionals moved all three joints. The EMG signals indicated a tendency for the frequency of variation of the beginners to be greater than that of the professionals. However, more data are needed to clarify this. | |||||||||||
