PURPOSE:To determine the positions of weld zones automatically and to improve the quality of the work by holding the joined parts of the work at a prescribed spacing between said parts, then bringing the joined parts in tight contact with each other, and locating weld zones always at the center of a torch without the effect of welding deformation. CONSTITUTION:In order to weld both end joined parts in the longitudinal direction of panels of radiators or the like to each other simultaneously, the work X1 from the position B is inserted into between a stopper 13 and a keep plate 15, and is positioned upright on a carriage 12 by means of springs 16. The work X1 is moved to the right by L+l, and is stopped when it contacts a position measuring device 22. The work X2 is carried into the groove of the lower guide 17 right under the position B, and advances in an arrow direction (a) by 1 pitch in synchronization with the carriage 12. After descending of an I type guide 18, a device 20 presses the work X2 and erects it upright. The work X2 is positioned by descending of a V-shaped guide 19 to maintain the spacing DELTAl from the work X1, then these are clamped by supporting plates 24 and clampers 25. The guides 17-19 are returned to the home positions, and the work X2 is further pushed by a clamper 21 to be brought into tight contact with the work X1, after which the works are welded with a torch 23. Welding deformation is absorbed by the elongation or contraction of the springs 16. |
