In the present invention, in order to solve the above problems, a plurality of square tubular steel materials are welded together with a diaphragm plate interposed between them, and lid plates are welded at both ends. In manufacturing a pillar material, a plurality of square tubular steel materials, which are constituent members, a diaphragm plate, and a lid plate are aligned and housed in a set car, and after the constituent members are tightened and held in the set car, The set car holding the members is arranged rotatably around an axis at a predetermined position on the bed, the movement of which is controlled in the XY directions, and the components inside the set car are set from the laser welding machine facing above the bed. While irradiating the required position with a laser beam, the bed is moved in the X or Y direction, and the set car is rotated to weld the components to each other, and the completed pillars are taken out from the set car. It was.

In the above method, the irradiation position of the laser beam by the laser welding machine can be changed by changing the angle of the reflecting mirror provided on the way of the laser beam. Further, the laser beam by the laser welding machine can be changed. The irradiation position can be roughly changed by changing the angle of the reflecting mirror provided on the way of the laser beam, and the minute change can be made by moving the bed in the X direction or the Y direction.

The pillar 1 is welded as shown in FIG. That is, first, a plurality of square tubular steel materials 2, which are the constituent members 2,
3, 4 and diaphragm plates 5, 6 and lid plates 7, 8 are aligned in the order of welding and housed in set car 10. As shown in FIG. 5, the set car 10 has a fastening fitting 11 on one end side. Therefore, after the constituent members 9 are aligned and housed in the set car 10, the fastening metal fitting 11 is operated to tighten and hold the fastening metal fitting 11 in the axial direction.

Next, the set car 10 holding the constituent members 9 is set on the bed 12. Bed 12
The movement in the XY directions is numerically controlled, and the component 9 can be positioned at a predetermined position. Holding members 13 and 14 for holding the set car 10 by sandwiching the set car 10 at both ends in the axial direction are provided on the bed 12. Each holding member 1
3, 14 are provided with rotation mechanisms 15 and 16 capable of rotating the set car 10 around its axis. One of the holding members 13 is configured to be upright and inclinable so that the set car 10 can be taken in and out by opening the holding member 14 and the holding member 14 at the time of falling.

A laser welding machine 17 is exposed above the bed 12. This laser welder 17
A reflecting mirror 19 is provided on the way of the laser beam passage 18. The reflecting mirror 19 is configured so that the angle can be changed, and by changing the angle, the irradiation position of the laser beam can be changed and the irradiation position can be set at a predetermined position on the component 9.

Thus, the component 9 held in the set car 10 is moved in the XY directions on the bed 12, and the angle of the reflecting mirror 19 is adjusted to determine the irradiation position of the laser light. The positioning is performed in conjunction with a sensor (not shown). The laser beam irradiation position by the laser welding machine 17 is roughly changed by the laser beam passage 18
By changing the angle of the reflecting mirror 19 provided on the way,
Small changes are made by moving the bed 12 in the X or Y direction. When the irradiation position of the laser light is determined, the bed 12 is moved in the X direction or the Y direction while the laser beam is irradiated, and the rotating mechanisms 15 and 16 are operated to rotate the set car 10 so that the constituent members 9 are mutually interlocked. Weld between.

When the welding of the constituent members is completed and the pillar 1 is completed, the pillar 1 is moved together with the set car 10 onto the moving base 20, the set car 10 is opened, and the pillar 1 is taken out.

As a matter of course, the present invention is not limited to the above embodiments, and various design changes and the like made within the scope of the present invention are also included in the scope of the present invention. .. For example, the combination of the constituent members of the pillar material 1 is not limited to the illustrated one, and the present invention can naturally be applied to other combinations. Further, the structure of the set car 10 can be variously changed according to the structure of the pillar 1.
