抄録
This paper gives an instance of recent progress which has led to the capability of the visualization and prediction of welding arcs, though the dynamic observations of spectral image by a high speed digital video camera with a monochromator and also the calculations by numerical models. The dynamic observations lead to visualizations of metal vapor behavior in arc plasma and, for example, show the temperature minima at arc axis in GMA welding. Finally, we discuss plasma physics in welding arcs through numerical calculations, using the basic conservation equations of mass, energy, momentum, current and electron density of plasma physics. There is close interaction between the electrode, the arc plasma, the weld pool, and also the metal vapor, which constitute the welding process, and must be considered as a unified system.
