Abstract

PURPOSE: To avert the adverse influence by the unstable arc right after ignition by temporarily inhibiting the tracing controlling at the beginning of welding arc ignition in the automatic welding machine provided with NC and tracing controlling.
CONSTITUTION: The welding groove 4 of the works 2, 3 is detected by the arc detector 5 provided to the torch 1 which welds the works along their groove 4. Based on the signal of the detector 5, a tracing drive part 6 is properly moved in the Y-axis direction so that the torch 1 mounted to the drive part 6 is subjected to tracing controlling along the groove 4. The tracing control axes are constituted by the drive part 6 and sliding support shaft 7 for controlling. The shaft 7 is fixed in the Y- axis direction drive part 8 for NC, the drive part 8 moves along the Y-axis direction sliding support shaft 9 for NC, the shaft 9 is fixed in the X-axis direction drive part 10 for NC and the drive part 10 moves along the X-axis direction sliding support shaft 11 for NC. The tracing controlling is stopped for a fixed time at the beginning of the ignition of the welding arc and only the drive part 8, 10 controlling by NC data is done, after which it is shifted to NC and tracing controlling through timer changing-over.
