Flexible Welding Enclosure® for Welding down to 10 ppm

04W-FlexibleWeldingEnclosuresWhen welding titanium and zirconium joints it is important that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm).

A flexible welding chamber is available from Huntingdon Fusion Techniques HFT® for a fraction of the cost of a rigid welding chamber. Flexible Welding Enclosures® provide a technically viable option to what are very expensive rigid enclosures or welding chambers.

Ron Sewell, Chairman for Huntingdon Fusion Techniques HFT® said: “There are many requirements now for welding zones to be purged of oxygen down to as low as 10 ppm, which can be a problem when companies look the high costs of traditional metal chambers. Our Flexible Welding Enclosures® are an ideal solution.”

Keep a Low Cost ‘Eye’ on your Weld Purge

05W-PurgEye100-IP65-WeldPurgeMonitorWeld Purge Monitors® are an essential instrument to help obtain non-oxidised, zero colour welds by monitoring the oxygen content, when welding metals such as stainless, duplex and chrome steels, titanium and nickel alloys where a high quality weld is required.

Advancing in the science of manufacturing beyond other designs, Huntingdon Fusion Techniques HFT®’s market leading, low cost PurgEye® 100 can help to eliminate the post weld cleaning costs. It is these costs that otherwise make the high cost of each weld ultra significant.

A customer recently said: “The handy PurgEye® 100 is one of the best, if not the best residual oxygen detector instruments on the market today. With its digital residual oxygen level LCD screen readouts measuring as low as 100 ppm and its large user friendly viewing screen making it easier for me to read.

QuickPurge® your Pipes for Perfect Welds

Time is Money

W11W-QuickPurgePipeWeldPurgeSystemelders, supervisors, welding engineers, quality control personnel and others are kept waiting, sometimes for many hours, for stainless steel or titanium pipe joints to be purged of oxygen ready for welding. Weld purging is necessary to reduce the oxygen content below 50 parts per million so that the weld surfaces and the adjacent hot metal doesn’t oxidise and thereby cause loss of corrosion resistance and metallurgical imperfections.

Such time loss and excessive waste of argon gas can be avoided now because of QuickPurge® Tube, Pipe and Pipeline Weld Purging Systems designed and manufactured by weld purging specialists and developers, Huntingdon Fusion Techniques HFT®.

Whatever the size of pipe, QuickPurge® Systems reduce waiting times so dramatically that they pay for themselves in less than one weld.

The Key to Your Perfect Weld Purge


A unique Weld Purge Monitor® has been designed and developed that reads from atmospheric level of oxygen (20.94%), down to one part per million (0.0001%), breaking all technological boundaries in one instrument.

Huntingdon Fusion Techniques Limited HFT® continues to grow its innovation of Weld Purge Monitors® / oxygen analysers that were first invented and manufactured by the company over 40 years ago.

CEO for HFT®, Georgia Gascoyne said: “The PurgEye® 600 incorporates the features and benefits of all the other Weld Purge Monitor® designs in the HFT® Family Range, but for the first time, this one instrument has a full range of measurement reading from atmospheric concentration (20.94%), down to 1 ppm, accurate to 10 ppm. Readings are indicated either as parts per million or in percentage.”

Welding of Vacuum Tubing and Piping


Welds in tubing and pipework for vacuum systems should have many important characteristics. They ideally need to be manufactured from stainless steel, leak tight, the joints should have full penetration with excellent sidewall fusion, there should be no porosity and the finish should be free from oxidation and discolouration.

When welding these stainless steel tubes and pipes, it is important to purge the welding zone with an inert gas, usually argon, to prevent loss of corrosion resistance, oxidation, discolouration, metallurgical defects and to ensure a good internal weld profile.

After 40 years of innovation, design and manufacturing expertise in the field of tube and pipe weld purging, Huntingdon Fusion Techniques HFT® has introduced PurgElite®, a range of low cost Tube and Pipe Purging Systems to achieve a clean, oxide free, zero colour weld in such tubes and pipes. As well as vacuum tube and piping, PurgElite® can be used in any other industry where stainless steel or titanium is used.

No Lost Purge During Welding


Weld Purging stainless steel and exotic metal pipes before, during and after welding is necessary and welders often construct their own purging device made from wood, foam or paper.

These unsuitable dams may leak or slip from position, flooding the welding zone with oxygen and resulting in an unsuccessful weld. The alternative to the homemade devices is to fill the entire pipes with expensive argon gas for the duration of the weld.

Weld Purging Experts Huntingdon Fusion Techniques HFT® have designed and developed Argweld® Weld Purge Film® kits to address these issues, ensuring weld purging is not only affordable, but also successful.

The Water Soluble Weld Purge Film® can also be used for open assemblies and closing welds, producing an impenetrable purge barrier.

Weld Purge your Pipes the “Elite” Way

06W-PurgEliteWeldPurgeSystemsWhen welding or tack welding stainless, duplex, chrome steel and titanium tubes and pipes, it is important to purge the welding zone with an inert gas to prevent corrosion, oxidation, discolouration and to ensure a good internal weld profile with no metallurgical defects.

Georgia Gascoyne, CEO for HFT® said: “We recently had a customer who was wasting a lot of money in time and argon gas costs by filling entire pipework fabrications with argon in order to weld the stainless steel pipes in an inert environment.There were several 90o bends in the pipework, so the customer thought filling the whole pipework system was the only option.”

Switch to MultiStrike® for an improved and safer Tungsten Electrode performance

01W-MultiStrikesTungstenElectrodesTungsten Electrodes are used when arc welding with the GTAW/Tungsten Inert Gas (TIG) process or PAW/Plasma welding. Other than to start the process, it is necessary to grind tungsten electrodes after they have touched the molten weld pool or the filler rod to the tungsten, which is not only time consuming but can also be a hazard to health.

Recognising both the performance requirement and the risk to health posed by thoriated tungsten electrodes, Huntingdon Fusion Techniques HFT®’s MultiStrike® Tungsten Electrodes not only deliver an increased performance, they also reduce the risk to health.
