極の数だけ必要であった。Conventionally, electrogas welding has been used for welding a vertical butt joint of a thick plate, but the limit plate thickness of this is approximately 50 mm even if the wire is oscillated back and forth. Met. On the other hand, the present applicant has previously proposed a two-electrode electrogas arc welding method according to Japanese Patent Application No. Hei 8-227338, which has enabled one-pass welding up to a plate thickness of 70 mm. It is premised that two reel and wire feeding devices are used. On the other hand, in a world other than electrogas arc welding, two-electrode arc welding and arc welding with more electrodes are common (eg, two-electrode CO 2 horizontal fillet welding, three-electrode submerged arc welding). Even if
The wire feeding reel required the number of electrodes and the wire feeding device required the number of electrodes.

For gas arc welding,
The more the torch of the special invention as shown in Japanese Patent Application No. 8-227338 must be used, the closer the electrodes are, and the more the feeding device itself needs to be placed in a narrow place.

Reference numerals 21 and 21 denote chips using two known electrogas arc welded chips. Reference numeral 20 denotes an attachment for chip attachment, which has an elliptical cross section and has holes D at intervals of D as apparent from the cross section A of FIG. The mounting screw is cut into the attachment so that the defective chip 21 can be replaced. The interval of D depends on the thickness of the steel sheet, but is preferably set to 10% to 60% of the thickness of the base material, for example, in the range of 5 to 30 mm.

B can be supplied while maintaining the interval of D, and the tips of the two welding wires 2A and 2B guided by the tips 21 and 21 of the torch 13, respectively, are inserted in the groove 2 in the base material cross-sectional direction. By oscillating the torch 13 in the fore-and-aft direction (base material cross-sectional direction) of the groove, the groove cross section can be evenly melted by the arc. As described above, placing two wire feeding reels and two feeding devices in a welding place using such a torch 13 is very problematic in terms of workability.

れるようにした。The process leading to the present invention will be described step by step. For example, as means for sending out two wires, the wire is first wound with two wires on one reel. As means for separately taking out two wires from the wire feed reel, a wire separating piece was first provided. Next, the number of wire feeding grooves cut into the wire feeding roller was reduced to two. The length of the wire feed roller is correspondingly longer, but in this case,
The wire strainer (a pair of rollers) also has a longer length,
It is preferable that the length of the wire pressing roller is also increased. Next, two wire outlets were provided so that the wire could be sent to two torches.

ものである。That is, the present invention relates to a wire feeding device for a multi-electrode gas shielded arc welding for simultaneously generating an arc from a plurality of electrodes, a welding wire feeding reel in which a plurality of wires are wound on one reel, and the wire. Between the feed reel and the corresponding wire cable outlets,
A wire separating piece for separating a plurality of wires from the reel and taking out the wires, and a wire feed roller having a number of roller grooves corresponding to the number of the wires are provided.

同じ早さで溶けていく。According to the present invention, the two wire supply speeds are always the same. It seems to be a little hard to use for two electrode welding of normal gas shielded arc welding,
In the case of electrogas arc welding, the distance between the wire tips is small and welding is always one pool (two wires are supplied to the same welding pond), so that there is no problem even if the wire feeding speed is the same. Even if only one of the wires melts too quickly, the self-control function of the arc length works because of the power supply with constant voltage characteristics. Then, only the other wire melts quickly and repeats this process. The book wires melt at the same rate.

る。The reason will be described with reference to FIG. First, in (A), when one wire is fed, it is assumed that welding is performed at the standard current IO . If the arc length is increased for some reason, such as when the torch is moved or the steel plate has a valley or the like, the voltage does not change in the constant-voltage characteristic power supply, and the current is small and becomes I-. When the current becomes smaller, the amount and speed of melting of the wire become smaller, and a reaction is performed so that the arc length becomes shorter. That is, if the arc length becomes longer, the user himself controls so that the arc length becomes shorter.

オーダーで両ワイヤ共均等に溶けていくこととなる。The same applies to the case of the two wires 2A and 2B.
As shown in (B), assuming that two wires A and B are arcing at the same arc length, if for some reason only B melts too much and the arc length of the B wire becomes longer, In the constant voltage characteristic, the current of the wire of A increases and
The current of the wire A decreases, the melting speed of the wire A increases, and the melting speed of the wire B decreases. Then, the arc length of the wire A becomes gradually longer, and the arc length of the wire B becomes gradually shorter, so that the wire returns to the same length. In this way, if a power supply with constant voltage characteristics is used, the arc length is automatically shortened or lengthened without any special operation, and both wires are evenly distributed in the order of seconds. It will melt.

ことになる。In the case of this apparatus, only one wire feeder is required, but two power supplies are required. However, since the place of the power supply may be different from the wire feeder, there is no problem in workability. This requires only half the wire feeder of the prior art and improves workability. With this efficiency, obstacles to the practical application of two-electrode electrogas arc welding are eliminated, and the realization is approaching.
