Shields maintain argon gas coverage during weld cooling to prevent oxidation

Huntingdon Fusion Techniques HFT® offers Trailing Shields® designed to ensure that welds stay under a protective argon gas cover while the hot weld metal is cooling to prevent oxidation on contact with air.

They are available in a flat style for sheet metal welding or in a curved style for welding circular items such as tubes, pipes, and tanks of all diameters. The shields can be fitted to all brands of GTAW and plasma welding torches. Longer and wider versions are available for automatic welding.
