Abstract
PURPOSE: To high accurately detect the relative position of the backing metal and the point just under the torch, and also, to achieve simultaneously the miniaturization of the detecting system and the removal of influence of the external light, by burying the photodetector in the backing metal being just facing against the molten metal, in the one side automatic welding.
CONSTITUTION: The emission of light from the arc at the point just under the torch 3 is detected by the respective photodetector 8a, 8b, through the transparent packing tape 6; the output of this photodetector is amplified 10a, 10b, and further, is inputted to the differential amplifier 11 for obtaining their deviation output. Next, this deviation output is inputted to the comparator 12, and is compared with the suitable synchronous travel signal being previously given by the setter 13, and then, the differential signal as the result of comparison is inputted to the controller 14 for the backing metal's traveling speed. Then, the speed of the driver 7 for self-traveling is controlled by the control signal output 15 of the controller 14.
