Protective coating and coated welding tip and nozzle assembly
First Claim
1. A welding aid for use with a high-temperature exposure article configured for exposure to a predetermined temperature comprising a particulate titanium dioxide weld spatter adhesion inhibitor and a liquid carrier for the adhesion inhibitor, whereby the mixture of the adhesion inhibitor and the liquid carrier is capable of being applied as a coating upon a surface of the article to form a thermal barrier that inhibits adhesion of weld spatter to the article.

Abstract
A coated welding tip and nozzle assembly is disclosed. The tip and the nozzle are coated with a coating composition comprising titanium dioxide. The coating provides resistance to adhesion and accumulation of weld spatter on the nozzle and tip and facilitates weld spatter removal. The coating also protects against thermal damage of the nozzle by providing a thermal barrier.

9. A coated welding assembly, comprising:
-
a nozzle assembly configured for heating a workpiece to a temperature sufficient to weld the workpiece; and
a thermal barrier provided upon at least a portion of a surface of the nozzle, the thermal barrier comprising a titanium dioxide weld spatter adhesion inhibitor so that the thermal barrier inhibits adhesion of weld spatter to the nozzle assembly. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

- 21. A welding nozzle for a welding gun comprising a nozzle adapted to substantially surround a welding tip of the welding gun and having an interior surface operatively disposed adjacent the welding tip and an exterior surface opposite said interior surface, at least a portion of the interior and exterior surfaces of the nozzle having a thermal barrier disposed thereon, wherein the thermal barrier comprises a titanium dioxide weld spatter adhesion inhibitor so that the thermal barrier inhibits adhesion of weld spatter to the nozzle.
