Abstract

PURPOSE:To suppress irregular rocking of a welding metal and to obtain stable penetration, by periodically varying a peak current value of a welding current having a pulse waveform, in case of consumable pulse arc welding. CONSTITUTION:A peak value Ip of a welding current (i) controlled to a pulse waveform is controlled, for instance, to a sine wave, so that it is varied periodically within a range of a current which is larger than a critical current value Ic. In accordance with this variation period, arc force is varied, a weld metal of a molten pool 7 follows little by little in the advancing direction of a wire 8. Accordingly, stable penetration which scarcely causes variance is obtained.
