- the zinc of the galvanized 10 is vaporized, and this vapor zinc tends to diffuse from the root portion 11 through the molten pool to the outside.
- the solidification rate of the molten metal is high, the vapor zinc cannot be sufficiently diffused to the outside and remains as pores 16 in the weld bead 7 or on the surface of the weld bead 7.
- the pore 16 stays in the weld bead 7, it becomes a blow hole.

- FIG. 1 shows a state of a welded portion when welding is performed using a welding power source device, a wire feeding device, an industrial robot, or the like (not shown).
- a welding wire 2 is automatically fed by a wire feeding device (not shown) through a welding torch 1 attached to a manipulator (not shown) constituting an industrial robot.
- a welding power source device (not shown)
- an arc 5 is generated between the wire 2 and the upper plate 3 and the lower plate 4 which are galvanized steel plates. 3 and the lower plate 4 are melted and welded.
- the arc force generated by the arc 5 acts as a force that pushes the molten pool 6 in the direction opposite to the welding progress direction. Is moved in the opposite direction.
- the root portion 11 which is a portion where the upper plate 3 and the lower plate 4 are overlapped is exposed.
- the route portion 11 has a length corresponding to the length of the upper plate 3 and the lower plate 4, but a portion where the route portion 11 of the portion being welded is exposed is shown as an exposed portion 9 in FIG. 2B. Yes.
- the welded portion becomes high temperature due to arc heat from the arc 5 or heat conduction from the molten pool 6, and the upper plate 3 and the lower plate 4 are in a molten state to generate a molten portion 8.
- the temperature of the melting part 8 exceeds the boiling point of zinc, and zinc is vaporized.
- the molten pool 6 is pushed in the direction opposite to the welding progress direction, and the exposed portion 9 in the route portion 11 between the upper plate 3 and the lower plate 4 is exposed. . Therefore, vaporized vapor zinc is easily released to the outside.
- the galvanized vaporized portion which is a portion where galvanized vaporized, is in a state where no zinc is present.
- the melt pool 6 is pushed in the direction opposite to the welding progress direction by the arc force of the arc 5 during the arc period.
- the route part 11 which became a high temperature state by the arc heat and the heat conduction from the molten pool 6 is exposed as the exposed part 9, and the vapor zinc generated from the galvanized steel sheet easily diffuses to the outside.
- release to the exterior of the vaporized zinc is accelerated
- the main force required to push the molten pool 6 is the arc force due to the welding current during the arc period. It is important that this arc force is large when the arc length is short. That is, by applying a large current at the moment when the short circuit is opened, a large arc force can be generated, and the molten pool 6 can be largely pushed.
- the increasing slope 15 of the welding current from the current 12 immediately before the arc re-generation to the first welding current 14 and the magnitude of the first welding current 14 are important parameters.
- the increasing slope 15 of the welding current is generally intentionally made gentle. The reason is that when the welding current is sharply raised, a phenomenon such as the molten pool 6 oscillating or the behavior of the droplets is increased, a micro short circuit is likely to occur, and the spatter increases.
- steam can be suppressed significantly by making the increase inclination 15 of welding current steep, enlarging the force which pushes the molten pool 6, and making it easy to discharge
- the first predetermined time 13 is the time from when the arc is generated until the first welding current 14 is finished. Further, in FIG. 2C and FIG. 2D, regarding the welding current, if a constriction that is a predictive phenomenon that the short circuit is released during the short circuit period is detected, the current 12 immediately before the arc re-generation is lower than the welding current at the time of detecting the constriction. To control the welding current. Then, when it is detected that the short circuit has been opened, an example in which an increase in welding current is started by an increase slope 15 of the welding current is shown.
- Table 1 shows a relationship between a combination of the increase slope 15 of the welding current 15 from the current 12 immediately before the arc re-generation to the first welding current 14 and the value of the first welding current 14 and the defect.
- Table 1 shows a relationship between a combination of the increase slope 15 of the welding current 15 from the current 12 immediately before the arc re-generation to the first welding current 14 and the value of the first welding current 14 and the defect.
- ⁇ the case where defects are not observed on the surface or inside after visual or X-ray analysis after welding
- X the case where defects are observed
- the appropriate value of the increasing slope 15 of the welding current is 750 A / msec or more, and the appropriate value (current maximum value) of the first welding current 14 is 300 A or more.
- the 1st welding current 14 should just be 300 A or more, and the increase inclination 15 of a welding current should just be 750 A / msec.
- the magnitude of the first welding current 14 that can be actually output and the increase slope 15 of the welding current are limited by the ability of the welding power supply device that outputs the welding current.
- the increase slope 15 of the welding current is more preferably set to 750 A / msec or more and 4000 A / msec or less.
- Table 1 shows an example in which the welding method is MAG welding, a solid wire with a wire diameter of 1.2 mm, a lap joint with a plate thickness of 2.3 mm, and a basis weight of 45 g / m 2 . The result of welding in case is shown.
- the maximum value of the first welding current 14 in CO 2 welding is preferably 450 A or less.
- the maximum value of the first welding current 14 exceeds 450 A, although depending on the plate thickness, the welding object is likely to be burned out.
- the welding current is sharply reduced to a value lower than the welding current immediately before the occurrence of the arc. That is, by reducing the welding current sharply to the current 12 immediately before the arc re-generation that is lower than the welding current at the time when the constriction state is detected, it is possible to reduce spatter at the time of arc occurrence.
- the welding stability is improved by controlling the distance between the wire 2 and the molten pool 6 to be a predetermined distance (for example, about 1 mm to 10 mm). That is, by feeding the wire 2 backward, it is possible to increase the distance between the tip of the wire 2 and the molten pool 6 and suppress a micro short circuit, thereby suppressing the occurrence of sputtering. be able to.
- the feeding speed in the case of normal feeding is higher than the feeding speed in the case of constant feeding welding that is generally performed. Therefore, it is easy to generate a short circuit, the occurrence of the short circuit is ensured, and there is an effect of reducing spatter. Moreover, since the short circuit can be mechanically opened at the time of reverse feeding, the short circuit can be reliably opened. Therefore, since a short circuit (minute short circuit) that occurs immediately after the short circuit is released can be reduced, it is possible to reduce spatter.
- the short circuit period is ended and the arc period is started, and the wire 2 is fed forward (forward feeding).
- the arc period ends and the short-circuit period begins.
- the above-described forward feed control and reverse feed control of the wire 2 are performed by periodically repeating the forward feed and the reverse feed of the wire feed speed at a predetermined cycle WF and a predetermined amplitude Wv. May be.
- the wire feeding speed of FIG. 3 has shown the case of a sine wave form as an example of periodic feeding.
- the present invention is not limited to this, and a trapezoidal wave shape or a sawtooth wave shape may be used as long as it is a periodic waveform.
- the molten pool is pushed so that the root portion that is the overlapping portion of the members is exposed.
- the gas generated from the base material can easily escape from the exposed portion.
- spatter can be suppressed remarkably, and it carries out with respect to the base material which gas generate
