    摘要： A method for arc welding can control the increase slopes of the short-circuit current and the inflection point of the increase slopes in the welding start period to be smaller than in the steady-state welding period. Thus, the increase slopes of the short-circuit current and the inflection point are made different between the welding start period and the steady-state welding period, thereby reducing sputtering in the welding start period.

    摘要： A wire feeding speed is decreased to a level lower than a base wire feeding speed in a short-circuiting period, and set to the base wire feeding speed in an arcing period. During the arcing period, a welding current is increased to a predetermined peak value by means of current control from the start of arcing to a first predetermined time, the welding current is then supplied with a welding voltage, a source voltage of which is controlled constant, from the first predetermined time to a second predetermined time, and the welding current is decreased to a predetermined base current by means of current control from the second predetermined time until the end of the arcing period.

    摘要： An arc welding method of the present invention controls a short-circuit current increasing gradient (di/dt), an inflection point at which the short-circuit current increasing gradient (di/dt) changes, the current in a peak period and in a base period, and the time of the peak period in accordance with a difference between a set voltage and an output voltage. This allows the output voltage to be matched with the set voltage, and stabilizes the arc. Thereby, a stable arc welding method can be implemented, even as a method for outputting a welding current based on a welding voltage.

    摘要： If a short circuit does not occur during deceleration of a wire feed speed in forward feed of a welding wire before the wire feed speed reaches a predetermined wire feed speed, a cyclic change is stopped and the wire feed speed is constantly controlled at the first feed speed. If a short circuit occurs during forward feed at the first feed speed, deceleration from the first feed speed starts, and the cyclic change is resumed for welding. This achieves uniform weld bead without increasing spatters even if any external disturbance such as change of distance between a tip and base material occurs.
