ABSTRACT:
An erosion resistant torch for use in a solid free form fabrication system for manufacturing a component from successive layers of metal feedstock material. The erosion resistant torch includes a torch structure defining a torch nozzle formed of a highly conductive bulk material. The erosion resistant torch further includes a gas flow channel and an orifice defined therein. An arc electrode is disposed within the gas flow channel. An erosion resistant material is disposed between the torch nozzle and the arc electrode in the form of a coating layer or an erosion resistant insert. The erosion resistant material is formed of one of a refractory material or a ceramic material.
