The tip of the raw steel plate 3 collides with the stopper plate 26.

When the material steel plate 3 collides with the stopper plate 26, the energizing plate 44 is sandwiched as shown in FIG. 4, the electric circuit is energized, and the detection switch 42 is turned on.
The roller conveyor 10 is transmitted to the controller 46, and the roller conveyor 10 is stopped by a command from the controller 46, and at the same time, a robot (not shown) mounted on the carriage 22 is operated. Alternatively, the detection switch 42 may not be attached to the stopper plate 26, and the operator may visually confirm that the material steel plate 3 has reached the position of the stopper plate 26 and operate the robot by the control device 46.

Since the robot stores a preset pattern for the gas fusing torch 24 to move in a required movement pattern, the robot moves the carriage 22 and the horizontal frame 23 according to the set pattern. As the origin G of the moving pattern of the gas fusing torch 24, for example, as shown in FIG. 5, a position corresponding to a length 1 required as a diaphragm backing material from the stopper plate 26 is selected.

Thus, as shown in FIG. 3, the horizontal frame 23
While ejecting the combustion flame of propane gas and oxygen gas from the two gas fusing torches 24 attached to the two, the two gas fusing torches 24 are first moved from the origin G in the same movement pattern at the same time as indicated by the arrow a. The steel plates 3 are brought close to each other and the movement is temporarily stopped at the point H to preheat the fusing start point of the raw steel plate 3.

At the timing of completion of preheating, as shown by arrows b and c, it moves while changing the direction to perform right-angled notch fusing, and then as shown by arrow d, oblique notch fusing in two directions, Further, the fusing work of moving as indicated by arrows e and f to perform fusing at a right angle notch is continuously performed to separate the residual material 5 from the raw steel plate 3 and drop it downward.
