Low Cost Weld Purge Monitoring down to 10 ppm

For many years, oxygen monitors and gas analysers have been used for weld purging. They are specifically designed and calibrated for accuracy at atmospheric oxygen level but not for weld purging where accuracy is required when reading much lower oxygen levels. Using the latest scientific knowledge and innovation, Huntingdon Fusion Techniques HFT® have designed and […]

Large Diameter Pipe Purging

Care is necessary when welding large diameter pipework in stainless, duplex, chrome steels, nickel alloys and zirconium. When welding such reactive materials, they need to be purged of oxygen before, during and after welding, which can cause a huge expense when they are of a large diameter. Weld Purging Experts Huntingdon Fusion Techniques HFT®’s innovative […]

Weldability of Grade 9 Titanium Alloy

The increasing popularity of Grade 9 titanium alloy has brought with it some questions about weldability. Grade 9 titanium alloy contains 3% aluminium and 2.5% vanadium, less alloying material than the more common Grade 5 (6% aluminium and 4% vanadium). Grade 9, alternatively referred to as Ti-3-2.5, offers improved resistance to corrosion and better mechanical […]

Improved Performance when using MultiStrike® Tungsten Electrodes

Tungsten Electrodes are used during Tungsten Inert Gas (TIG) or Plasma welding and are the most important consumable during welding. However they are often manufactured using thoria, dust from which poses a risk to health. Recognising both the performance requirement and the health benefits, Huntingdon Fusion Techniques HFT®’s MultiStrike® Tungsten Electrodes not only deliver an […]

Weld Purge Plugs for Low Cost Tube and Pipe Purging

For welding nickel alloy, titanium and stainless steel tubes and pipes, including stubs, elbows and tees, Huntingdon Fusion Techniques HFT® have designed and developed clinically clean, white nylon Weld Purge Plugs™, providing a great barrier for weld purging. Luke Keane, Technical Sales Manager for HFT® said: “When other purge systems cannot be used, Weld Purge […]

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 […]

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 […]

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 […]

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 […]
