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 resistant properties. What […]

Dew Point Sensor

Dew Point Sensor: 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. We have recently added a Dew Point Sensor to our range […]

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 PurgEye® Desk is leading the […]

The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® provides a cost saving solution to carrying out repairs or modifications on pipes with liquid inside. Qwik-Freezer™, the industry standard portable CO2 Pipe Freezing System requires little set-up time and is the only low cost CO2 Pipe Freezing System capable of making ice plugs in pipes up […]

Welding Titanium

Welding Titanium Techniques for successful welding of titanium. Weld Purging of titanium joints. As titanium is a reactive metal, correct weld purging is possibly more critical than with most other metals. There are some major elements whilst welding titanium, to ensure successful welds are achieved. A good source of weld purge gas. Welding gas suppliers […]

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, […]

Accurate 10 ppm Weld Purge Monitor®

Reactive alloys such as zirconium and titanium present challenges to welding engineers. Many industries today are using these materials for their durability and high corrosion resistance properties, but are faced with having to avoid expensive waste and rework. An effective Weld Purge Monitor® present, in conjunction with weld purging equipment, when making joints will ensure […]

PurgEye 600, Unique, Weld Purge Monitor®

Our all in one, colour touch-screen PurgEye 600 with PurgeNet™ reads from atmospheric, down to 1 ppm oxygen (accurate to 10 ppm). Here are some of our Frequently Asked Questions. Q. What is the intended application for the Argweld® PurgEye 600 Weld Purge Monitor®? For weld quality control in aerospace, semiconductor, pharmaceutical, vacuum, biotech, food […]

High Precision Tungsten Electrode Grinder

To produce optimum arc stability, improve arc starting and subsequently weld quality, a dedicated Tungsten Electrode Grinder should be used for sharpening all Tungsten Electrodes during TIG welding. Huntingdon Fusion Techniques HFT® state-of-the-art TEG-1000 Tungsten Electrode Grinder will ensure the grinding of each Tungsten Electrode results in clean and smooth finishes, with no splintering and […]

New Rubber PetroChem Stoppers

We have recently launched new Rubber PetroChem Stoppers, for pipe stopping where access is difficult. Here are some of our Frequently Asked Questions. Q. What are the Rubber PetroChem® Stoppers commonly used for? A. The PetroChem® Stoppers are most commonly used for Construction site drain testing operations, debris stopping during machining operations, leak testing of […]

Weld Purging of Heat-Treated Pipework

Some high strength steels need to be pre-heated prior to welding and may also require a post-weld heat-treatment. Both pre- and post- weld heat treatment is necessary to prevent cracking, but temperatures up to 300ºC (572ºF) must be maintained for lengthy periods. To prevent oxidation, the inside of piping needs to be purged continuously using […]

Stainless Steel Pipe Welding Made Easy

Welders often face difficulties when welding stainless steel T piece joints, dome end connections and closure welds, where a tandem Inflatable Pipe Purging System is unsuitable. Weld Purge Dams from Huntingdon Fusion Techniques HFT® offer a great solution, available for pipe sizes 6 to 88” (150 – 2,235 mm). Georgia Gascoyne, CEO for HFT® said: […]
