Huntingdon Fusion Techniques® (HFT®) new, low-cost Argweld® Weld Trailing Shield® provides additional inert gas coverage during welding.
The Trailing Shield® is connected to the inert gas supply, diffusing gas without turbulence through multi layers of stainless steel mesh built into the body of the shield. At each side, replaceable silicone rubber side shields provide a barrier to prevent the gas escaping sideways. As the welding torch is moved forward, the weld remains under an inert gas shield until the welded metal has cooled below its oxidation temperature.
Trailing Shields® are reusable, with a temperature resistance of up to 230°C. They prevent re-work, eliminate the need for an expensive purge chamber and allow for faster welding.
