This shows the normal shape of the first layer bead 60a when welding is performed by filling an appropriate amount of the cut wire cw. FIG. 7B shows a case where the amount of the cut wire cw filling the groove space is too small. If the amount of the cut wire is too small, the heat input of the welding torch applied to the butted portions of the thick plates W1 and W2 becomes excessive, and the back formed on the welding line on the back surface of the plate (on the line formed by the V-shaped lower part). The width of the bead 60 becomes too wide, and the back bead 60 overflowing the depression on the upper surface of the backing material BP is overwrapped (excessive heat). FIG. 7C shows a case where the amount of the cut wire cw filling the groove space is too large. If the amount of the cut wire cw is too large, the heat input of the welding torch applied to the butted portion of the thick plates W1 and W2 is insufficient, and the cut wire is formed on the welding line on the back surface of the plate (on the line formed by the lower part of the V-shape). Back bead 60 does not come out sufficiently (too little heat). FIG. 7D shows the V formed by the thick plates W1 and W2.

For example, when the gap W = 0, the cut wire scattering height H
A good back bead was obtained in the range of 8.5 mm to 10.5 mm (marked by O). If the spraying height was lower than this, the amount of cut wire sprayed was reduced, resulting in excessive heat input and back bead. -Is slightly wider (squares). Conversely, if the spraying height is higher than this, the amount of cut wire sprayed will increase, so that the heat input will be insufficient and the back bead will be slightly narrower (diamond mark). It becomes difficult to melt because it becomes high, and it becomes a bad bead such as poor fusion due to insufficient heat input (triangle mark). Other gap values (3,5,6,7mm)
The same tendency is observed in the above case, and the range in which a good back bead is obtained is a portion surrounded by oblique lines.

布する装置の提供が望まれる。As shown in FIG. 7, it is necessary to appropriately spread the filler material (cut wire) to fill the substantially V-shaped groove space in order to improve welding quality. It is also important in improving the efficiency of welding work. In the aspect in which the worker holds the pot and sprays as described above, the position (posture, height) of the pot with respect to the groove tends to change as the worker walks, and the spraying amount tends to become unstable. When trying to keep the position of the pot relative to the groove to keep the spraying amount uniform, the worker performs a short pitch low-speed walk while maintaining a bent posture,
Work that is likely to cause stress physically and mentally is required. Therefore, it is desired to provide a device that automatically and stably sprays an appropriate amount of cut wire.

5, a cut wire cw (a filler material) is charged. The inserted cut wire cw descends in the hose 36 and comes out to the groove α. However, when the support base 19 is stopped, the cut wire cw that has come out of the groove is below the hose lower end portion 36a. When the opening level is reached, the cut wire cw stops flowing down into the hose.
When the support base 19 moves in the x direction, the cut wires sequentially come out of the groove as shown in FIG. During the running (spraying), the knob 34 can be turned to adjust the spraying amount (the height of the hose lower end portion 36a). Even if the relative distance between the support base 19 and the groove α changes, the copying table 28 moves in the y direction along the copying roller 29, and the opening of the hose lower end 36a is always positioned at the center of the groove. I do.

逆となり、カットワイヤ散布量は減少する。When the support base 19 is moving in the x-direction, the groove copying roller 29 sinks deeply into the groove where the V-shaped groove α is wide (see the two-dot chain line & ((B) of FIG. 5)
Therefore, the copying table 28 rotates counterclockwise (FIG. 5 (b)), and the hose lower end 36a is raised, so that the amount of cut wire sprayed increases. The opposite is true where the groove width is narrow, and the amount of cut wire sprayed decreases.
【0046】この様にして開先幅の変動に応じたカット
