Back Purging with Argweld® Weld Backing Tape®

Back Purging is the process of protecting and shielding the back side or under side of the weld during welding to prevent oxidation. Back Purging with fiberglass Weld Backing Tape® supports weld roots and can prevent oxidation, sugaring, achieving clean, oxide free welds. Luke Keane®, Technical Sales Manager for Huntingdon Fusion Techniques HFT® said: “We […]

Expanding Rubber Plugs for use with Oils, Hydrocarbons and Petrochemicals

Often, pipes containing oils, hydrocarbons and petrochemicals need to be blocked but not all plugs are suitable for such applications. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® manufacture a range of Rubber Plugs, for fast, reliable and safe pipe stopping. Ron Sewell, Chairman at HFT® said: “There are many applications where our Rubber Plugs […]

Distance Weld Purge Monitoring

GTA/TIG welding long pipelines made of stainless steel can be found in many different industries including Oil and Gas, Nuclear and LNG. The use of stainless steel can offer many advantages including corrosion resistant properties and cost-effectiveness of the alloy. With Stainless Steel being a reactive material, the oxygen in the protective gas must be […]

Save Time and Money with a High Quality Inflatable Purging System

When welding tubes and pipes made of alloys such as stainless, duplex and chrome, it is important to eliminate the oxygen internally with an inert gas. This will help prevent oxidation, discolouration and will ensure a good internal weld profile. Weld Purging long pipelines can be costly and time consuming, so restricting weld purge volumes […]

HFT Distributor Training Course

HFT Distributor Training Course: We held our first Distributor training of 2020 here at our UK HQ in Burry Port last week of January. Distributors from Italy, Norway, Scotland and various parts of the UK took part, the first training course we had held in our new conference room. During the first morning, Technical Sales […]

Weld Purging at a Low Cost

There are many occasions where Tandem Inflatable Tube and Pipe Purging Systems are not suitable and welders are often left to construct their own Weld Purging Equipment. Often, homemade purging devices are unsuitable and can often lead to loss of welds due to oxidation. Weld Purging Experts Huntingdon Fusion Techniques HFT® manufacture a range of […]

Eliminate the Thoria and Maintain the High Performance with Blue-Tipped MultiStrike® Tungsten Electrodes

Thoria, found in thoriated Tungsten Electrodes is a radio-toxic compound and emits mainly alpha particles, which are harmful if released inside the digestive tract or inside the lungs where they act as a carcinogen. Thoriated Tungsten Electrodes therefore pose a risk to welders during grinding. Why are thoriated Tungsten Electrodes still in use today? Welders […]

Tungsten Electrode Grinder for perfectly ground Tungsten Electrodes

Tungsten Electrode Grinder: Correctly preparing each Tungsten Electrode for welding is crucial. It is one of the most important variables in TIG / GTA welding and each Tungsten Electrode must be ground properly to improve arc starting, stability and subsequently weld quality. Manufactured with a diamond wheel, the TEG-1000 Tungsten Electrode Grinder from Huntingdon Fusion […]

Welding Enclosures for Titanium Parts

Welding titanium alloys often has to be carried out in an environment where oxygen can be eliminated throughout the welding cycle. If the parts were to come into contact with oxygen ay any point, the reactive metal can become contaminated, oxidising which can lead to reductions in corrosion resistance and mechanical strength. Metal glove boxes, […]

Focus on Additive Manufacturing

“Additive Manufacturing (AM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers.” – The Welding Institute. The advantages: Additive Manufacturing allows for the creation of bespoke parts, design flexibility, rapid product development and very little wastage. Parts and products can be […]

Oxygen Monitor for Field Welding

Welding under site conditions introduces problems that are not found in normal factory environments. Exposure to heat and cold, sand and dust, damp and wet atmospheres place demands on standard Weld Purge Monitors® for which they are not designed to meet The PurgEye® Site, available from Weld Purging Experts Huntingdon Fusion Techniques HFT® is protected […]

Pipe Freezing for Pipe Repairs and Maintenance

Pipe freezing is fast becoming one of the most efficient ways to make pipe repairs or to carry out pipeline maintenance. By creating an ice plug, fluids inside the pipe can remain present, rather than having to drain down the entire system. Here are some of our frequently asked questions regarding the Pipe Freezing System, […]
