The development of the automatic control system was made to detect 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, the principle and the algorithm of direct arc observing method which improves the reliability of weld line tracking, and the synthetical control algorithm to realize the full automatic control are described. 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 ovserving method. (2) The welding apparatus and the algorithm for synthetically controlling were manufactured as a trial. (3) As the experimental result of automatic control, the control apparatus and the algorithm were certified to be used practically.
