抄録

Numerical simulations have revealed various large current phenomena with improvement in the calculation speed of a computer. For example, detailed modeling was conducted in numerical simulation of arc discharge for arc welding or circuit breaker. Especially, in application of arc plasma to material processing such as arc welding, understanding and control of thermal and dynamic interactions between plasma and material are indispensable for improving quality and efficiency of the process. In this paper, recent studies on numerical simulation of arc welding are introduced.
