Abstract
A welding torch (10) for welding on a component has an electrode (12) within a nozzle (14) through which a flow of gas passes. A shield (20) defines an enclosure (22) around the nozzle (14). Means are provided for supplying weld filler material (18) into the vicinity of the electrode (12) through the shield (20). One end of the shield (20) is attached to the welding torch (10). The other end of the shield (20) is open and extends towards the component (16). An inflatable seal (28) is mounted on the end of the shield (20) to seal between the shield (20) and the component (16).
