抄録
In the present paper, the mechanism of metal vapor in arc plasma is discussed through the dynamic observation of spectra of helium, chromium, manganese and iron during stationary TIG welding of stainless steel. Wavelengths from 400 nm to 700 nm are observed by a monochromator with a diffraction grating. Radiation from the arc is sent to the nomochromator through optical lens and spectroscopic images are captured with 500 fps by a high-speed digital video-camera. Spectra of metal elements exist locally in the arc plasma due to dependence of plasma temperature and also intensive region of each metal spectrum depends on kinds of metal elements. The most part of metal vapor produced from the weld pool surface are carried on the cathode jet and then are swept away towards surroundings of the arc. However, if the driving force like diffusion in plasma is large, some metal elements can get across the cathode jet and then can be carried on the circulation flow towards tungsten electrode.

In the present paper, the mechanism of metal vapor in arc plasma is discussed through the dynamic observation of spectra of helium, chromium, manganese and iron during stationary TIG welding of stainless steel. Wavelengths from 400 nm to 700 nm are observed by a monochromator with a diffraction grating. Radiation from the arc is sent to the nomochromator through optical lens and spectroscopic images are captured with 500 fps by a high-speed digital video-camera. Spectra of metal elements exist locally in the arc plasma due to dependence of plasma temperature and also intensive region of each metal spectrum depends on kinds of metal elements. The most part of metal vapor produced from the weld pool surface are carried on the cathode jet and then are swept away towards surroundings of the arc. However, if the driving force like diffusion in plasma is large, some metal elements can get across the cathode jet and then can be carried on the circulation flow towards tungsten electrode.
