PURPOSE:To improve efficiency in welding execution and conveying operation by conveying base metals for welding while regulating the lateral displacement thereof and welding the base metals by welding devices fixed above the base metals. CONSTITUTION:A pair of right and left parallel frames 13 are provided above a conveyor supporting base 12 and a plate material 14 tack welded with skeletal materials 20 are moved by revolving rollers 15. Positioning rollers 16 which contact the side ends of the material 14 are provided to prevent the displacement such as hunting or the like of said material in the direction perpendicular to the advancing direction. The central axis of the rollers 15 is inclined in vertical and horizontal directions respectively. Welding devices 21 of as much as the number of the materils 20 are fixed to a gate-shaped cross beam 19. When the rollers 15 are driven to rotate, the one side end face of the material 14 contacts with the rollers 16 and moves and the parts 23 to be welded are automatically welded. The conveyance of the base metals for welding and welding execution are made possible by the flow operation according to the above-mentioned mechanism and therefore the efficiency is improved. |
