Abstract

PURPOSE: To obtain the titled device which provides copying control with high precision by supervising a rotary arc in a groove to be welded via a television camera and by processing the video signal of the same for prescribed control.
CONSTITUTION: Welding core wire 3 is curved and rotated to rotate the end of the core wire around welding nozzle 2, generating arc 4. Television camera 6 fitted to a welding torch, etc., supervises and picks up a weld zone in a groove slantingly from above to detect right and left groove ends 1 and the center of rotary arc 4 and then outputs its video signal to groove copying controller 7. This copying controller 7 performs the prescribed compression processing and groove copying arithmetic processing for the video signal and, on the basis of the processing results, supplies a right-left movement signal to a torch right-left moving motor 8 to execute copying control. Simultaneously, said video signal and the copyig arithmetic processing result are outputted to monitor television 9 to confirm the control state.
