Abstract
A variable orifice torch for use in a solid free form fabrication system for manufacturing a component from successive layers of metal feedstock material. The variable orifice torch includes a torch structure defining a torch nozzle formed of a highly conductive bulk material. The variable orifice torch further includes a gas flow channel and a variable orifice defined therein. An arc electrode is disposed within the gas flow channel. The variable orifice is defined in the torch nozzle and in alignment with the arc electrode. The variable orifice is coupled to the torch structure in a manner operable to control a flow gas therethrough by varying the size of an aperture defined by the variable orifice.
