WELDING GUIDE NOZZLE INCLUDING NOZZLE TIP FOR PRECISION WELDWIRE POSITIONING

摘要

A welding guide nozzle for precision weld positioning of a feedstock materia l in a welding system. The welding guide nozzle includes a nozzle structure definin g a substantially cylindrical holding apparatus that tapers at one end to define a nozzle tip. The holding apparatus and the nozzle tip include concentric bores defined therein. An erosion resistant rod is disposed within the bore defined in the nozzle tip. The erosion resistant rod includes a bore defined therein into with the weld feedstock material is disposed. The erosion resistant material is formed of a high heat resistive material thereby permitting positioning in close proximity to a heat source.
