Avoid Putting Welds at risk with Weld Purging Dams

For closure welds, tight bends, T piece joints and dome end connections, a range of low cost, single ended Weld Purging Dams is available from Weld Purging Experts, Huntingdon Fusion Techniques HFT®. Manufactured from low vapour pressure materials, Weld Purging Dams are in use for where a conventional Tandem Weld Purging System cannot be used. […]

Glass Fibre Weld Backing Tape® for Perfect Welds

Supporting the backside or under side of weld joints will help prevent oxidation, eliminate re-welding and require much less post-weld cleaning. Weld Backing Tape® available from Huntingdon Fusion Techniques HFT® supports weld roots, reducing sugaring and oxidation. Georgia Gascoyne CEO Managing Director for HFT® said: “Low cost Weld Backing Tape® is very easy to use. […]

Remote Weld Purge Monitoring

The exposure to oxygen during the welding process on alloys such as stainless steel will result in discolouration and can severely reduce corrosion resistance properties. It is therefore crucial that the oxygen level is monitored throughout the welding process and kept to a desired level. However, is often difficult for welding personnel to get an […]

Eliminate Porosity During Welding with a Dew Point Sensor

The presence of moisture on the joint surface can create porosity in the weld metal. It is therefore important that the dew point is monitored so that welders are made aware when moisture is likely to be present. Innovators in Weld Purging Huntingdon Fusion Techniques HFT® have recently developed the PurgeNet™ Dew Point Purging Gas […]

Pipe Purging with Water-Soluble Weld Purge Film®

When it comes to pipe purging, it is not desirable, nor cost effective to simply pour inert gas into the pipe assembly in the hope that a good purge is achieved. A tough, leak tight purging barrier is required. To keep purging costs down, Weld Purging Experts, Huntingdon Fusion Techniques HFT® have designed and developed […]

Reliable Oxygen Monitor for Titanium Welding in Aerospace Applications

Prior to welding of titanium, widely practiced in the aerospace Industry, the oxygen content of the purge gas must be reduced to a level below 50 ppm. Engine components such as discs, blades, shafts and casings, from the front fan to the rear of the engine, and fasteners, airframe components and landing gear are all […]

Easy Valve Replacement with CO2 Pipe Freezing

The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® provides a cost saving solution to carrying out repairs or modifications on pipes with liquid inside, which also includes valve replacement. Replacing valves in pipework can be a challenge, especially when the pipelines have liquids running through them. One option is to completely drain the system to […]

Improve Weld Purging Quality with the PurgEye® 600

With the ever-increasing activities in such industries as the Nuclear, Oil and Gas and Engineering, there is a large volume of stainless steel, zirconium and titanium pipework that will need to be welded to a very high standard. An effective Weld Purge Monitor® present, in conjunction with weld purging equipment when making joints will ensure […]

Heavy-Duty Pipe Stopping with Steel Plugs

Heavy-duty leak testing, sealing, pipe blocking and stopping is easy with Steel Plugs from the Pipestoppers®. Steel Test Plugs can be used for low pressure testing and plugging pipes, pipelines and pipework fabrications and other orifices between 2 and 48” (50 to 1,200 mm) diameter. Luke Keane, Technical Sales Manager for HFT®’s Pipestoppers® Division said: […]

Perfectly Ground Tungsten Electrodes

When it comes to TIG welding, Tungsten Electrodes are the most important part of the application. A properly ground Tungsten Electrode will help to improve arc starting and stability, giving an overall better performance. Huntingdon Fusion Techniques HFT® manufactured the TEG-1000 Tungsten Electrode Grinder with a diamond wheel, resulting in clean and smooth finishes, with […]

Weld Purging with Preheat

In the power generation and nuclear industry, low and medium alloy steels such as SA 213 T91 and SA 335 P91 are chosen for their high strength, but are often prone to cracking during welding. Pre-heating and post-heating reduces the crack sensitivity. In order to meet the requirements of inert gas purging when temperatures exceed […]

Easy Pipe Welding

Typically for closure welds, tight bends, T piece joints and dome end connections where a conventional Tandem Weld Purging System cannot be used, a range of low cost, single ended Inflatable Weld Purge Dams is available for pipe diameters from 6 to 88 inches (150 mm up to 2,235 mm). Weld Purge Dams from Huntingdon […]
