できる。In the figure, reference numeral 1a is an inlet side clamp device which can be shifted in the line flow direction following a guide rail by driving a hydraulic or pneumatic cylinder, and a backing metal 2 which serves as a backing plate during welding. And is driven by, for example, a hydraulic or pneumatic cylinder 3. Further, the delivery frame 4 is equipped with a butt gap adjusting device 5 according to the present invention for positioning the backing metal 2. The adjustment of the abutting intervals of the welding start point and the end point of the preceding material 6b and the following material 6a is performed by shifting the inlet side frame 1a by hydraulic pressure or by driving a variable pressure cylinder, and after positioning so as to always be in an overbutting state. , The thickness of the fixed mechanical stoppers 7a provided on both the work side side and the drive side side of the output side frame 4 or the liner 7b attached to the backing metal 2 is changed, and the position of the backing metal 2 in the height direction is changed. By changing. For example, the preceding material 6
When the thickness of the liner 7b is set so that the level of the backing metal 2 is higher than the clamp level of the b and the trailing material 6a, the abutting end faces of the leading material 6b and the trailing material 6a are The state shown in Fig. 3 is pushed up to the state shown in Fig. 3, and the abutment interval T 2 becomes wider than the abutment interval T 1 . As described above, by arbitrarily changing the thickness of the liner 7b, it is possible to easily adjust the butt spacing in units of micron, more easily than the conventional method of adjusting the butt spacing in the line direction.

Then, for example, as shown in FIG. 4, butting interval δ 2 >
It is possible to arbitrarily perform the slope butting that results in δ 1 .
The backlash between the fixed mechanical stopper 7a and the liner 7b and the backlash between the liner 7b and the backing metal 2 at this time disappears when the backing metal 2 is lifted by the hydraulic pressure or the pressing force of the pneumatic cylinder 3.

In order to manage the facing end of the abutting portion of the trailing member 6a, the abutting interval is detected by image processing or the like having a traveling function in the plate thickness direction via the screw shaft 19 and the rail 20 by the electric motor 18, for example. The measurement sensor 21 for measurement is attached. Then, the butt spacing is directly measured by image processing or the like, combined with the device shown in FIG. 7, and the butt spacing adjusting device 5 is controlled to obtain the optimum butt spacing between the material to be welded, that is, the leading material 6b and the trailing material 6a. In addition, it is possible to automatically monitor the adjustment of the matching distance in real time.
