A ceramic nozzle lens is a type of welding nozzle that combines the functions of a nozzle and a gas lens. It is designed to improve shielding gas coverage and flow in the weld area and provides a more stable welding arc. The lens is made from a high-temperature ceramic material that is resistant to heat and wear.
Ceramic nozzle lenses offer several advantages in TIG welding, including improved gas flow control and coverage, a more stable welding arc, and reduced weld defects. They also help to protect the tungsten electrode from contamination and extend its lifespan.
The choice of ceramic nozzle lens depends on the specific welding application and the preferences of the welder. Factors to consider include the material being welded, the size of the weld area, and the desired shape of the welding arc.
