摘要： A welding control method for a welding device having an output characteristic with a predetermined gradient showing a relation between a welding output voltage and a welding output current. By setting a set target welding voltage that is higher than the set initial welding voltage according to a difference between the set initial welding voltage and the welding output voltage, the welding output voltage is controlled to be the set target welding voltage. Thus, a proper arc length can be achieved early by correcting the change of the arc length due to, for example, motion of the hands of a welding operator.

摘要： An arc welding method relates to consumable electrode arc welding in which a welding wire feeding rate suitable for a welding current is determined as an average feeding rate, and the short circuit state and the arc generation state are alternately generated by changing the wire feeding periodically and repeatedly between the forward feeding and the reverse feeding. The method offers arc welding with the average feeding rate according to a welding current, a predetermined frequency, and a predetermined velocity amplitude. In the method, at least any one of the frequency and the velocity amplitude is set to a value suitable for the welding current.

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： An arc welding control method for carrying out welding by generating an arc between a wire and a base material. The wire is fed at wire feed speed (Wf) of periodically repeating forward feeding and reverse feeding with predetermined frequency and amplitude from time point (100) at which start of the welding is instructed, or from a certain time point (101) after the start of the welding is instructed, and then the wire feed speed is changed to a constant speed. Since the wire feed speed is controlled by periodically repeating forward feeding and reverse feeding at the arc start, short-circuit can be opened regardless of the electromagnetic pinch force, and spatters, which are generated at the early stage of the arc start because a molten pool is not preset, can be reduced.
