Ceramic Gas Nozzles for TIG
Innovacera Advanced Ceramic Gas Nozzles for TIG made from the highest grade alumina, present high spatter resistance, high heat resistance, high strength, good insulating ability and excellent corrosion resistance in a wide range of operating temperatures and conditions, and suit the highest demands of industrial applications with the combination of its technical features.
Core Function
During the TIG (Tungsten Inert Gas) welding process, the ceramic nozzle serves two functions: 1.Guide the shielding gas (such as argon) Allow the gas to flow uniformly towards the welding pool, forming a protective gas shield. 2. Prevent oxidation contamination Isolate the oxygen and nitrogen in the air to prevent the welds from oxidizing or forming pores.Material Properties
