Abstract
A method of and system for steering an arc and/or torch head in a weld joint is provided. The system includes a torch head that creates an arc in a weld groove formed in at least one workpiece. The system also includes a control unit that includes a feedback system that monitors at least one of a voltage of the arc, a current of the arc, a power output of the torch power supply, and a contact tip to weld distance. The control unit outputs a feedback signal corresponding to the monitoring. The control unit also includes a comparison circuit that compares the feedback signal with at least one predetermined value corresponding to a position of at least one of the arc and the torch head in the weld groove. The control unit further includes an arc steering system that outputs a steering signal based on the comparison.
