Research Abstract

The future goal of this research is to innovate on arc welding technology from “skill” to “science”, because arc welding technology is necessary as a basic technology for manufacturing industries. The approach of this research for getting the future goal is firstly (1) the visualization of metal vapor behavior and fume formation in arc plasma during welding and also is secondary (2) the numerical simulation of total system of arc welding process. From both results of experiments and calculations, (3) dynamics of elemental separation of metal vapor in arc plasma during welding and mechanism of fume formation are revealed.
