| 发明名称 | Arc welding control method and arc welding control system | ||
| 摘要 | A welding control method alternately repeats a short circuit period, during which a welding wire and an object to be welded short-circuit, and an arc period, during which an arc is generated and discharged, to weld the object to be welded. The method compares average output voltage, which is an average of welding voltage calculated during welding, to set voltage preliminarily set, and controls a welding output current produced when an arc is generated based on the comparison result therefrom, to regulate the meltage of the wire for adjusting the arc length, which brings the short circuit cycle closer to a constant one when a disturbance (e.g. extended or shortened arc length) occurs. | ||

| 主权项 | 1. An arc welding control method in which an object to be welded is welded by alternately repeating a short circuit period, during which a welding wire and the object to be welded short-circuit, and an arc period, during which an arc is generated and discharged, the method comprising: comparing average output voltage, which is an average of welding voltage calculated during welding, to set voltage preliminarily set; and controlling a welding output current produced when the arc is generated based on the comparison result therefrom, such that the welding output current produced when the arc is generated is calculated using a difference between the average output voltage and the set voltage, wherein, when the average output voltage is higher than the set voltage, a welding output current produced when the arc is generated is controlled such that the welding output current is smaller than a given current value preliminarily set, based on a difference between the average output voltage and the set voltage, and wherein, when the average output voltage is lower than the set voltage, the welding output current produced when the arc is generated is controlled such that the welding output current is larger than the given current value, based on the difference between the average output voltage and the set voltage. | ||
