抄録

It is possible to improve the visual information, which is obtained from the arc welding process, by taking the wavelength spectrum into consideration.<BR>In the first stage of this paper, the spectrum of welding arc and molten pool is measured with a grating monochrometer. This measurement indicates that CO₂ arc, Ar arc and molten pool have their characteristic spectrum respectively.<BR>The images of the arc welding process are improved and the configuration of the molten pool is relatively emphasized by selecting the image pickup device and the optical filter on the basis of the spectrum characteristics in the next.<BR>The bead width and the penetration depth are measured by digital processing of these images in real time in the final stage and the results of measurement agree well with the actual bead width and penetration depth.
