Weld Purge Film for a Variety of Pipe Sizes

Low cost weld purging a variety of tubes and pipes sizes can be achieved by the use of low cost Weld Purge Film®.

Weld Purging Experts, Huntingdon Fusion Techniques HFT® recommend switching home made dams produced of unsuitable material, to their low cost Weld Purge Film® to achieve oxide free, zero colour welds.

Ron Sewell, Chairman for HFT® said: “Weld Purging can be challenging as well as expensive, which is why many welders today continue to construct their own dams to cut costs. Homemade dams made from material such as foam, sponge or paper can often lead to loss of welds when they leak or slip from position thus flooding the welding zone with air. 

“Our Weld Purge Film is great for when mechanical purging devices cannot be retrieved. The Film, which does not contain water, unlike paper and sponge products do, can be used to create an impermeable barrier, but can be easily washed away after use without leaving any residue.”

The water-soluble Weld Purge Film® allows dams to be cut easily with the safety knife provided and once they are fixed into position using the water-soluble Weld Purge Super Adhesive® provided, produce an impenetrable purge barrier that can easily be washed away during hydrostatic testing of the pipe or just by normal wash-out.

These affordable Kits will save operators high costs by minimising gas usage dramatically reducing purge time and eliminating the need to clean or possibly replace a failed weld. Weld Purge Film® Kits have been designed and developed by HFT®, containing product accessories needed to manufacture dams that will not come loose during welding.

After welding, the water-soluble film is simply washed away and dissolved leaving no trace.

Low Cost Monitor for Welding Titanium and Stainless Steel

Titanium and stainless steel are both reactive alloys. When they are heated during the welding process, they will react with any air that is present, causing oxidation, which can lead to a loss of corrosion resistance properties. Shielding the metal with an inert gas is therefore crucial and one wa ...

Accurately Measure the Dew Point During Purging

During purging welders need to measure the oxygen content but also need to measure the ‘dew point'. The dewpoint is the temperature where condensation begins and water will condense on the material being welded. This can affect the weld properties significantly. Georgia Gascoyne, CEO for HFT® sai ...

Pipe Purging Monitor

What is Weld Purging? Weld Purging is the displacement of oxygen by an inert gas (usually argon) from the vicinity of a weld, before, during and after welding. It is crucial to displace the oxygen when welding many metals to help achieve oxide free, zero colour welds with no loss of corrosion resis ...

Reliable Oxygen Analyzer for Welding Titanium

When welding titanium, it is essential that the oxygen level surrounding the weld is purged down to as low as 50 ppm. Measuring the oxygen level with a reliable oxygen analyzer is the most efficient way to know exactly when to commence welding. Specifically designed for Purge Chamber welding, the ...
