Abstract:
1. A method of welding comprising: moving a welding torch in a welding direction with respect to a workpiece joint to be welded; during moving the welding torch, feeding a first welding wire through a first welding wire guide having a proximal end coupled with a nozzle end body of the welding torch and a distal end, the first welding wire guide defining a first welding wire orientation, and feeding a second welding wire through a second welding wire guide also having a proximal end coupled with the nozzle end body of the welding torch and a distal end, the second welding wire guide defining a second welding wire orientation that is divergent and non-coplanar with respect to the first welding wire orientation; and wherein feeding the first welding wire and feeding the second welding wire each further include feeding the welding wires through the corresponding welding wire guides from the nozzle end body of the welding torch toward at least one of, a welding travel plane aligned with the welding direction and intersecting a point on the nozzle end body located between the proximal ends of the first and second welding wire guides, and a second plane which is normal to the welding travel plane and also intersects a point on the nozzle end body located between the proximal ends of the first and second welding wire guides.
