ABSTRACT:
A system and method for weld line profile control wherein an electrical quantity corresponding to the arc of a welding torch is detected and the deviation between the electrical quantity and a reference quantity is monitored so that correction movements of the welding torch relative to the weld line can be limited if the deviation exceeds a predetermined value. In more detail, an electrical quantity corresponding to the arc of one side waveform of a welding torch operating under the influence of a wave signal is detected and a reference quantity corresponding to the arc of the other side waveform of the welding torch is detected, and the deviation between the electrical quantity and the reference quantity is monitored to provide a signal limiting the correction movements of the welding torch relative to the weld line when the deviation exceeds a predetermined value.
