Weld Purging Accessories are designed to help welders achieve oxide free welds in Chrome-Steels, stainless steels, titanium, zirconium and magnesium every time, regardless of budget.
Weld Purging Experts, Huntingdon Fusion Techniques HFT® recognise the need for consistent, high quality welds and therefore design and manufacture a Range of low cost Weld Purging Accessories for all applications and budgets.
Trailing Shields® are low cost Weld Purging Accessories and simply attach onto any TIG/GTAW, PAW/Plasma and MIG/GMAW welding torch, providing an additional inert gas coverage during the seam welding of stainless steel, duplexes, titanium and any other reactive metal where discolouration or oxidation needs to be eliminated.
The lightweight, easy to use Trailing Shields® pay for themselves in just one weld! They are perfect for manual welders, as well as automatic machines by helping to cover the weld with an inert gas coverage during and after welding, producing bright, shiny, oxide free welds time and time again and eliminating the expensive post weld cleaning process.
The Trailing Shield® is connected to the argon gas supply, diffusing gas evenly without turbulence through the 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 argon escaping sideways and remaining over the weld metal. As the welding torch is moved forward, the weld remains under an argon gas shield until the welded metal has cooled below its oxidation temperature.
Argweld® Trailing Shields are available in flat format for straight line welding as well as in curved format for any diameter of pipe or vessel from ½” (12mm) upwards.
As well as external models, there are curved models for the insides of pipes and tanks.
