Abstract
Manual welding continues to be an indispensable skill in custom fabrication and high-mix low-volume production. Hence, skilled welders are needed throughout the metal working industry. On the other hand, many people have little inducement to enter the field because of high physical risk and the demanding training required. Virtual reality technology may provide an effective solution, and several VR systems have been proposed for welding training. Such VR simulations offer the possibility of safe and highly efficient training. This paper deals with a high efficiency training method for manual arc welding, which employs a simulation of a simplified, idealized welding situation. In the proposed method, trainees are presented with an idealized, easy-to-weld situation in the beginning stage of training, and the welding challenges gradually become more difficult and realistic in the following stages. Experimental results show the proposed training method can reduce the fatigue reported by trainees.
