A gas shield strip cladding welding system including a workpiece, a strip of welding material, an enclosure having an opening through which the strip of welding material passes, a feeder for controllably passing the strip of welding material into the enclosure through the opening, a gas delivery conduit connected to the enclosure so as to pass a shielding gas into the enclosure adjacent to the strip of material, and a power supply electrically connected to the strip of welding material and to the workpiece such that an arc is produced when the strip of welding material comes into close proximity to the workpiece. A mechanism is connected to the enclosure so as to move the enclosure continuously relative to the workpiece so as to deposit the welding material in a desired pattern. The shield gas includes an inert gas. The gas delivery conduit includes a first gas line connected to the enclosure so as to deliver the shield gas to one side of the strip of material and a second gas line connected to the enclosure so as to deliver the shield gas to an opposite side of the strip of material.
