In automatic butt welding of relatively thin plates, it is important to control welding condition in order to obtain a sound full penetration weld. Recently, it was reported that there is an intimate relationship between the oscillation of molten pool and penetration. Accordingly, a control system of welding condition in TIG are welding according to the frequency of molten pool was constructed. But it is difficult to detect the molten pool oscillation, if width of the molten pool is under 5mm. Therefore, pulse-shielding gas oscillating method that is more sensitive in detecting oscillation than pulse current oscillating was proposed. In this study, detection system of the peculiar frequency of the molten pool and control system of the welding condition were constructed in TIG are welding with pulse-shielding gas oscillating method.
