PURPOSE: To shorten the working term, improving working safety and working accuracy by providing one set of conveying device with a welding machine, which can shift the upper part of a preparing stage for frame and the adjoining upper part of a base plate for assembling panel, and two sets of conveying device for the frame.
CONSTITUTION: When the conveying device 8 with the welding machine comes on the base plate 6 for assembling the panel, fine adjustment is executed and a clamping device is descended and welding face in the frame 02 is press- contacted on a steel plate 01 prefixed to the base plate 6 for assembling panel. The automatic welding machine 10 in the conveying device 8 with the welding machine is descended near to the welding line in the steel plate 01 and each frame 02 is tack welded to the steel plate 01 along the welding line. When the automatic welding machine 10 reaches the welding running limit position in the welding line, only the conveying device 8 with the welding machine release the clamping device 9 and is shifted to the next tack welding position. By this method, as the frame is automatically tack welded on the steel plate without any man-labor at all, efficiency, labor safety and accuracy of the panel assembling work can be improved.
