Easy Stainless Steel Welding

Weld Purge Monitors® are in use throughout the Welding Industry. Used during the welding of reactive alloys, they ensure the oxygen present is at a low enough level to avoid oxidation, which can lead to a loss of the alloys’ corrosion resistance properties. For stainless steel, the oxygen level needs to be as low as […]

Argweld Weld Trailing Shields ®

Argweld Weld Trailing Shields ® provide an additional inert gas coverage during stainless steel and titanium pipe and sheet metal welding. The addition of a low cost, reusable Argweld Weld Trailing Shield ® can produce cost saving results. Here at HFT®, we pride ourselves on product development and with the support of our scientific knowledge […]

Need Superior Welds?

Reactive metals including stainless steels and titanium will react with air when they are heated during the welding process, which can cause oxidation and lead to a loss of corrosion resistance properties Huntingdon Fusion Techniques HFT® have recently launched their new and improved Argweld Weld Trailing Shields®, providing a high quality inert gas coverage during […]

Qwik-Freezer™ Pipe Freezing Equipment

Qwik-Freezer™ Pipe Freezing Equipment uses liquid carbon dioxide (CO2) to freeze stationary water in any chosen sections of pipe or tubing. Here are our Frequently Asked Questions…. What condition does the pipe and water inside have to be in?Ensure there is no flow of water through the pipe. The outside surface of the pipe must be clean […]

Portable Pipe Freezing System

It is often very challenging to carry out repair work on pipes containing liquids. One option to carry out this maintenance is to completely drain the system, which can prove costly. Pipe Freezing Experts Huntingdon Fusion Techniques HFT® has introduced the Qwik-Freezer™ Systems to their Pipestoppers® Division. These systems use CO2 to create ice plugs […]

Pipe Purging at a low cost with Weld Purge Film®

Titanium, stainless steel and other corrosion resistant materials are widely used for pipework. It is therefore necessary to ensure that a reduction in corrosion resistance does not occur during welding when elements are lost due to oxidation. The joint can be protected against oxidation using a technique called Weld Purging. Huntingdon Fusion Techniques HFT® have […]

Welding Enclosures for the Aerospace Industry

Welding Enclosures are in use by companies such as British Airways, Airbus, Pratt and Whitney, Lufthansa, Senior Engineering and Shapes Aerospace International along with many other companies in the Aerospace field. Available for a fraction of the cost of a rigid welding chamber, Flexible Welding Enclosures® provide a technically viable option to the very expensive […]

Stylish 1 ppm Weld Purge Monitor®

When welding reactive metals such as titanium, zirconium and nickel alloys, it is important to monitor the oxygen level before, during and after welding especially in industries where tubes and pipes must be free from oxidation with no metallurgical defects. Weld Purging Experts Huntingdon Fusion Techniques HFT® have designed and manufactured the PurgEye® 600, an […]

Diamond Wheel Tungsten Grinder

Diamond Wheel Tungsten Electrode Grinders are recommended for all tungsten electrode grinding. Tungsten is a very hard material and with the diamond wheel being a harder material it makes for a smooth grind. The Tungsten Electrode is one of the most important variables involved in TIG welding. Preparing your Tungsten Electrode correctly will help to […]

Welding Cr/Mo/V Steel Pipe Joints

Chromium/molybdenum/vanadium steels need to be pre-heated prior to welding and also require a post-weld heat-treatment in order to preserve the mechanical properties. These materials can also suffer from loss of elements through oxidation, thus changing alloy balance and affecting mechanical properties. Protection can be provided through the use of specially developed weld purge systems. Huntingdon […]

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. […]

Weld Backing Tape

Weld Backing Tape is a low cost way of supporting the backside of weld joints, helping to achieve oxide free welds and reducing re-welding post-weld cleaning. What is Weld Backing Tape manufactured from? Comprising of a 3" (75mm) wide aluminium adhesive tape backing strip, Weld Backing Tape has a 1" (25mm) wide band of woven […]
