Abstract
An electric arc welding system includes a welding torch having a head supporting a nonconsumable, elongated electrode for establishing an arc and between a work piece and an outer end of the electrode. The system further includes nozzle means for supplying an inert gas shield around the longitudinal axis of the electrode and said arc and conductor means for supplying current to the electrode for establishing and maintaining the arc. Means are provided for feeding filler wire toward the longitudinal axis of the electrode and the arc along a feed path intersecting the axis at an acute angle. The feeding means includes means for advancing the filler wire along the feed path in repetitive incremental strokes separated by alternating periods of stationary dwell.
