に、溶接精度が低下するという問題がある。 For example, the furnace wall of a boiler uses a water-cooled wall called a membrane panel to effectively recover the generated heat. This membrane panel is formed by interposing metal plates called membrane bars between multiple tubes arranged in parallel, and then fixing the membrane bars and tubes by welding to form a single plate. . FIG. 1 shows a membrane panel, where 1 is a tube and 2 is a membrane bar interposed between each tube 1. Each tube 1 and membrane bar 2 are formed into one membrane panel by welding 3. Ru. FIG. 2 shows a welding method for forming membrane panels. Welding of the membrane bar 2 and the tube 1 is carried out by starting from the starting end 2a and gradually moving in the direction of the arrow. Because the membrane bar 2 is more susceptible to thermal stress, the membrane bar 2 bends and deforms as shown by the symbol 2b during welding. For this reason, it is necessary to weld the membrane bar 2 while extending it horizontally by the impact force, and usually special personnel are assigned to drive the membrane bar, which is not only uneconomical but also reduces welding accuracy. .

The other end of the membrane bar 2 is connected to a traction device 10 such as a hydraulic cylinder, and during welding, a tensile force is applied to each membrane bar by the fixing device 8 and the traction device 10. In the above state, the automatic welding device starts welding from the above-mentioned starting end and moves in the direction of the arrow while pressing the membrane bar with the pressing roller 7. Even if the membrane bar tries to bend during this time, the bending can be effectively prevented by the pressing force of the pressing roller 7 and the traction force of the traction device 10. Note that code 1
1 is a rail for a mobile welding device.
