摘要： There is provided an arc welding control method of performing a forward/reverse feeding control of alternating a feeding rate of a welding wire between a forward feeding period and a reverse feeding period, and generating short-circuiting periods and arc periods to perform welding. The welding wire is fed forwardly at a time of staring the welding. The forward/reverse feeding control is started from the reverse feeding period of the welding wire after starting conduction of a welding current.

摘要： The present invention improves the stability of arc welding carried out by cyclical repetition of forward feed and reverse feed of a weld wire, An arc welding control method includes repeated forward feed and reverse feed at a weld wire feed rate, according to a prescribed cycle and a prescribed amplitude, and generation of short-circuit time intervals and arc time intervals to carry out welding, wherein the feed rate cycle and/or the amplitude are set automatically on the basis of the average feed rate and the welding rate, or the wire deposition amount per unit of weld length. Further, in the event that the amplitude has changed, feedback control of the forward feed-side shift amount is carried out in such a way that the average value of the feed rate is constant. In so doing, the feed rate cycle and amplitude are always set to optimal values.

摘要： There is provided an arc welding control method of alternating feeding of a welding wire between forward feeding and reverse feeding periodically according to a feeding rate pattern constituted of a forward feeding amplitude, a reverse feeding amplitude, a forward feeding period and a reverse feeding period, stored in correspondence to an average feeding rate setting value, and generating short-circuiting periods and arc periods to perform welding. An average feeding rate of the welding wire is detected, and at least one of the forward feeding amplitude, the reverse feeding amplitude, the forward feeding period or the reverse feeding period is changed so that the detected average feeding rate equals the average feeding rate setting value, thereby automatically correcting the feeding rate pattern.

摘要： There is provided an arc welding control method of feeding a welding wire according to a push-pull feeding control using a push-side feeding motor which rotates in a forward feeding direction at a feeding rate set to a push feeding-rate setting value and a pull-side feeding motor which alternates a forward feeding rotation and a reverse feeding rotation periodically, and generating short-circuiting periods and arc periods to perform welding. An average feeding rate of the pull-side feeding motor is detected. The push feeding-rate setting value is corrected to the detected average feeding rate of the pull-side feeding motor.

摘要： An arc welder includes a welding power supply, a forward/reverse welding wire feeder, and a controller for the power supply and the wire feeder. Welding is implemented by repeating unit welding steps each including a short circuit stage with the welding wire and a base material being short-circuited and an arc stage with an arc being generated between the wire and the material. A transition period continues from a starting point of the arc stage till the wire feeding rate reaches a forward maximum. An average welding current is defined as an average of the welding current during the short circuit and arc stages. Within the transition period, the controller sets a current suppression period during which welding current is smaller than the average welding current. Transition period length T0 and current suppression period length T1 are set to satisfy the inequality 0

摘要： There is provided an arc welding power supply. An output control unit outputs welding voltage and current in correspondence to each of a short-circuiting period and an arc period. A feeding control unit controls a feeding rate of a welding wire. A short-circuit forcibly generating period is provided between forward feeding acceleration and deceleration periods. In the short-circuit forcibly generating period, the feeding control unit increases the feeding rate with a change rate larger than a change rate during the forward feeding acceleration period and maintains a predetermined forward feeding peak value when the feeding rate reaches the peak value.

摘要： There is provided an arc welding control method of alternating feeding of a welding wire between forward feeding and reverse feeding periodically to generate a short-circuiting period and an arc period in a manner that shifting to the arc period is performed by reducing a welding current in the reverse feeding during the short-circuiting period.
