内に挿入される。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a plan view showing the configuration of an embodiment of the present invention, and FIG. 3 is a sectional view taken along the - line in FIG.
In these figures, the same reference numerals are given to the parts corresponding to those in FIG. 1, and the explanation thereof will be omitted.
In FIGS. 2 and 3, 9a and 9b are the presser plates 3a,
It is a rectangular parallelepiped-shaped recess formed in the upper surface of the back bar 1 below the back bar 1, and the bottoms of the recesses 9a and 9b are provided with biasing members 10a and 10 made of, for example, springs.
b is provided. Moreover, these recesses 9a, 9b
Rectangular parallelepiped-shaped positioning members 8a and 8b are fitted in the respective positioning members 8a and 8b so as to be movable in the vertical direction.
The lower surfaces of the biasing members a and 8b are in contact with the upper end portions of the biasing members 10a and 10b, respectively. Each of these positioning members 8a and 8b is connected to the biasing member 10 when the presser plates 3a and 3b are located a predetermined distance above the back bar 1.
The back bar 1 protrudes upward due to the biasing forces of the presser plates 8a and 10b, and on the other hand, when the presser plates 8a and 8b descend, the recesses 9a and 9b are caused by the pressing force of the presser plates 3a and 3b.

う。 When performing welding using the welding jig configured in this way, first, the materials to be welded 2a and 2b are placed so that the butt line 2c is located above the groove 5, and the starting end 6 is positioned. It is brought into contact with members 8a and 8b.
Next, by a pressurizing device (not shown), the presser plates 3a,
3b, the materials to be welded 2a, 2b are pressed and fixed by the holding plates 3a, 3b, and the positioning members 8a, 8b move the protruding parts of the materials 2a, 2b to the same height as the thickness of the materials 2a, 2b. The remaining parts are pushed into the recesses 9a and 9b. (See Fig. 3) In this state, the torch 4 is transferred from the origin position 11 shown in the figure to the starting end 6, and then the butt line 2 of the welded materials 2a and 2b is
Welding is carried out while moving above c to the terminal end 7.

ｂがトーチ４の走行を妨害することはない。 Thus, in the embodiment described above, the positioning members 8a, 8b protrude above the back bar 1 when the materials to be welded 2a, 2b are set on the back bar 1. Therefore, these positioning members 8a, 8b
By using this, it is possible to always set the materials to be welded 2a and 2b in a fixed position. On the other hand, during welding, the positioning members 8a, 8b are inserted into the recesses 9a, 9b.
b does not interfere with the running of the torch 4.
なお、付勢部材１０ａ，１０ｂの付勢力は押え
板３ａ，３ｂの押圧力よりはるかに小さくてよい
ことは言うまでもない。 It goes without saying that the urging force of the urging members 10a, 10b may be much smaller than the pressing force of the holding plates 3a, 3b.
以上、説明した様にこの発明によればバツクバ
