As a result, the inner surface of the notch 67 is brought into contact with the side surface of the longitudinal material 20, and one end of the transformer material 7 is brought into contact with the pusher 12 of the reference body 11 for positioning (state in FIG. 5). . Further, the elevating body 31A of each jacking device 31 is raised and lowered appropriately to bring the upper edge of the transformer material 7 and the skin material 19 into contact with each other.

Next, welding is performed for each longitudinal section. That is, welding is completed sequentially from the left end (or right end) longitudinal section. A detailed explanation is as follows.

As shown in FIG. 8 and FIGS. 11a to 11c, the upper edge of the transformer material 7 and the skin material 19 are welded by a traveling automatic welding device 17.

As shown in FIG. 10, the first and second clamping bodies 8, 10 in that section are lowered to remove the transformer material 7.
Separate from.

As shown in FIGS. 13a to 13c, the transformer material 7
and the left (or right) longitudinal material 20 are welded together.

As shown in FIGS. 12a to 12c, the left (or right) longitudinal member 20 and the bracket 68 and stiffener 69 attached to the transformer member 7 are welded.

Contrary to the above, the transformer material 7 and the right (or left) longitudinal material 20 are welded, and the right (or left) longitudinal material 20, the bracket 68 and the stiffener 69 are welded.

The posture of the traveling automatic welding device 17 is lowered, the robot moves to the adjacent longitudinal section, and the same operation is repeated.

As described above, according to the apparatus for assembling and welding skin material and transformer material of the present invention, the transformer material brought onto the foundation truck can be easily positioned in the longitudinal direction by being pressed against the reference body by the positioning device. By lifting it with a jacking device, the upper edge can be brought into close contact with the skin material, and by moving the movable body closer and bringing both clamping bodies into contact with both sides, the transformer can be removed. The transformer material can be quickly held by sandwiching it, and the transformer material and the skin material placed thereon can be continuously welded using a traveling automatic welding device. As a result, positioning, holding, and welding of the transformer material can be performed automatically and without much effort, and the construction period can be significantly shortened compared to the conventional method.
