HFT releases weld trailing shield

08 June 2017

Welding accessory developer Huntingdon Fusion Techniques® (HFT®) has released a range of Weld Trailing Shields®, designed for extended inert gas coverage during stainless steel and titanium welding to prevent oxidation.

The lightweight tool, available in the US from COB Industries, is designed to be easily manoeuvred around the pipe joint during welding and is connected to an argon (Ar) gas source with extra Ar flooding and covering the heat-affected zone next to the weld. As the welding torch is moved forward, the weld remains under the Ar gas shield until the welded metal has cooled below its oxidation temperature.

Each trailing shield is delivered with a variable diameter connector so that it can fit any size of tungsten inert gas/gas tungsten arc/plasma arc welding torch for manual or mechanised welding.
