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 […]

Welding Stainless Steel

Avoiding loss of corrosion Many industries rely on the corrosion resistance of stainless steels including the food, beverage, pharmaceutical, semiconductor, petrochemical and nuclear. It has become common practice in some applications to accept discolouration and remove it post-welding, but this can be very expensive. It is time-consuming and, where access is limited, difficult to achieve […]

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 […]

Replace Ceramic Backing Tape for Supported Weld Roots

Ceramic Backing Tape is often used to help support weld roots. However, with a melting point of 1,800ºC, concerns grow during TIG welding, where temperatures can reach up to 6,000ºC. Leaders in Weld Purging Technology, Huntingdon Fusion Techniques HFT® manufacture a range of Weld Backing Tape®, with no true melting point, helping to support weld […]

Weld Purging Tube and Pipes

When welding stainless steel, zirconium or titanium tubes and pipes, the oxygen must be purged down to a level where the alloy will not oxidise since this can lead to a loss of corrosion resistance properties. This is usually under 100 ppm for stainless steel and under 50 ppm for titanium. The Pre-Purge Process Displacing […]

Weld Purge Oxygen Monitor

Weld Purging is the act of removing oxygen from the vicinity of a weld, before, during and after welding reactive metals by displacing the oxygen with an inert gas (usually argon). When welding stainless steel, the oxygen level must be reduced to a required minimum, which is less than 100 ppm. The most effective way […]

Low Cost Pipe Purging with Weld Purge Plugs

Weld Purging small pipes of different diameters can be challenging, especially when budgets are tight. Often, welders are left to create their own homemade purging dams out of unsuitable materials such as foam, paper or cardboard. Weld Purging Experts Huntingdon Fusion Techniques HFT® manufacture a range of low cost, lightweight Weld Purge Plugs for a […]

Tungsten Electrode Performance

Tungsten Electrode: They are one of the most important consumables for all Tungsten Inert Gas (TIG) Welding. Careful selection and preparation can lead to an increase in electrode life and better welds. 1. Choose the right diameter Table 1 can be used to determine the electrode diameter best suited to the welding current you are […]

PurgElite® Tandem Pipe Purging System

Inflatable Tube and Pipe Purging Systems simplify the process of inert gas purging by restricting weld purge volumes, making huge savings in time and inert gas. Huntingdon Fusion Techniques HFT® design and manufacture PurgElite®, a range of low cost Tube and Pipe Purging Systems that help to achieve a clean, oxide free, zero colour weld […]

Thoriated Tungsten Electrodes are left in the dust with MultiStrike®

Red tipped thoriated Tungsten Electrodes are said to contain 1.70% to 2.20% thorium. Thorium improves the quality of Tungsten Electrodes but also has a radio-toxic compound posing a risk to welders, particularly during grinding. Huntingdon Fusion Techniques HFT®’s blue-tipped MultiStrike® Tungsten Electrodes contain a mix of non-radioactive rare earth elements, eliminating the risk to health […]

Low Cost Alternative to Metal Glove Boxes

There is an ever-increasing demand in industries such as the Aerospace, Medical and Motorsport for high quality welded titanium components. Often, welding has to be carried out in an environment under 50 parts per million throughout the welding cycle. Metal glove boxes were previously a big success, however with the lack of flexibility, heavy in […]
