The investigation on the automatic control system was made to detect the change in the groove width and the welding start and stop positions, to control the weld line tracking, and to set up the optimum welding conditions corresponding to the change in the groove width, for the purpose of the automatic control of the horizontal narrow gap welding. In this report, it is described as the principle and the algorithm of direct arc observing method which progress the reliability of weld line tracking, and as the synthetical control algorithm to realize the full automatic control. The results obtained are summarized as follows : (1) The weld line and the wire position can be detected stably within the accuracy of 0.5(mm) with the direct arc observing method. (2) The welding device and the algorithm which control it synthetically were manufactured as a trial. (3) As the experimental result of automatic control, the control device and the algorithm were certified to be used practically.
