The investigation and the trial manufacture on the automatic control system were made automatically to set up the optimum welding conditions corresponding to the change in the groove width of the joint, for the purpose of the automatic control of the horizontal narrow gap welding by the high-peak pulsed MIG welding method. Especially, even in case of the change in the groove width of the joint, the consideration is given to set up the optimum welding conditions to have satisfactory bead configuration and constant bead height, and the algorithm for these control was established. Moreover, an automatic control device making use of micro-computer was manufactured as experiment, and the effectiveness of this control method was demonstrated by the experiment with the device.
