Abstract

PURPOSE: To realize not only a reduction of the facility cost but an increase of the working efficiency, by performing the inner/outer welding via a unit of the running truck.
CONSTITUTION: The tube 13 to be welded is carried in at the inner surface welding position W1 and then turned by the rotating device 17 so that the area to be welded may be at the lowest part. Then the support roll 6 is moved down to have a contact to the auxilary truck 14, and the upper/lower positioning is given to the free-end part of the long-size beam 3. After this, the truck 1 is run in the direction of X1. The welding torch 8 is set at the end part of the tube 13 to be welded, and the guide roll 5 is engaged with the opening part 131 respectively. Under these conditions, the truck 1 is run in the direction of X2 to perform the welding. After the welding of the inner surface, the tube 13 is shifted to the outer surface welding position W2 via the position of the code W3. The tube 13 is turned by the device 17 to set the area to be welded at the highest part. Then the truck 1 is run in the direction of X1 to give the welding onto the outer surface via the welding torch 16 of the outer surface welding head 15.
