Abstract

A method of and a system (100) for steering an arc and/or torch head (120) in a weld joint (145) is provided. The system (100) includes a torch head (120) that creates an arc in a weld groove formed in at least one workpiece (115A, 115B). The system (100) also includes a control unit (190) 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 (190) outputs a feedback signal corresponding to the monitoring. The control unit (190) 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 (120) in the weld groove. The control unit (190) further includes an arc steering system (180) that outputs a steering signal based on the comparison.
