ABSTRACT:
A method and apparatus for automatic weld line tracing using a non-contact sensor for detection of a weld line, which sensor is continuously reciprocated across the groove. Signals produced from the sensor during the reciprocation are compared at the ends of the groove, and the lower voltage value of the two signals is determined. A value lower than the lower voltage of the two signals by .delta. is predetermined and the position associated with the value is detected by a displacement-measuring instrument, the output of which is utilized for control of the positions of a welding torch.
