WELDING ELECTRODES
 
Graphite Powder is used in Arc Welding Electrode manufacture as a component in the Flux.  Graphite’s high oxidation resistance enables it to combine with the molten weld metal material.  Precise Graphite particle size distribution ensures easy extrusion and elimination of cracks in the flux coating.
 
Graphite addition to the flux is primarily in hard facing electrodes and also in nickel and ferro-nickel core wire electrodes used for welding of cast iron requiring machining capability.
