Abstract
An integrated non-consumable electrode and filler material nozzle for use with electric arc welding (or arc brazing). The electrode and filler nozzle are preferably integrated in one or more of the following ways: mechanically, thermally or electrically. The filler nozzle may be used to feed either hot or cold wire. Electric arc power and the wire resistance-heating power may be supplied by a single arc welding power supply, which is either directly or indirectly shunted between the electrode and filler nozzle. The nozzle can be designed to feed either single or multiple filler wires. The hot-wire nozzle preferably has a movable contact element which allows the electrical extension to be adjusted. Also the curvature of the outlet end of the hot-wire nozzle can be adjusted. If the nozzle is vertical, a wire deflection device at the nozzle outlet can be used to deflect the tip of the filler wire toward the weld puddle.
