Weld Purge your Heat-Treated Pipes with HotPurge®

New power plants are in high demand and several hundred are expected to be built over the next decade. Chromium-molybdenum (chromoly) steel pipe such as P91 is a major construction material for the high pressure piping in these plants and there are particular techniques for welding this pipework to avoid potential catastrophe caused by oxidation. […]

Argweld Weld Trailing Shields ® of a high quality by Huntingdon Fusion

Argweld Weld Trailing Shields ® are a simple, low cost addition to any TIG (GTAW), MIG (GMAW) or Plasma (PAW) welding torch for oxide free welds. Argweld Weld Trailing Shields ® can be used for Circumferential TIG or MIG welds on Stainless Steel, Titanium, Nickel Alloys Chrome Steels and Magnesium tubes pipes and tanks as […]

Low Cost Weld Purging with Weld Purge Plugs™

Weld Purging smaller tubes and 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. Huntingdon Fusion Techniques HFT® have designed and developed clinically clean, white Nylon Weld Purge Plugs™, providing a […]

Advanced Weld Purging with the PurgEye® 200

Metallurgically sound and oxide-free welds are a minimum requirement now when welding stainless steel, zirconium, nickel alloys and titanium. Quality control procedures are in place within most industries and welders are no longer able to ‘guess’ when their oxygen level is low enough to begin welding. Oxygen levels as low as 50 parts per million […]

Weld Purging Accessories available at a Low Cost

Weld Purging Accessories are designed to help welders achieve oxide free welds in Chrome-Steels, stainless steels, titanium, zirconium and magnesium every time, regardless of budget. Weld Purging Experts, Huntingdon Fusion Techniques HFT® recognise the need for consistent, high quality welds and therefore design and manufacture a Range of low cost Weld Purging Accessories for all […]

Save Money by Restricting your Weld Purge Zone

It is often very common for welders to spend hours waiting for their weld purge level to be low enough to begin welding. Without restricting the purge zone with an inflatable pipe purging system when welding stainless steel, titanium or zirconium tube and pipes, displacing the oxygen in entire pipelines with an inert gas (usually […]

Highly Accurate 100 ppm Weld Purge Monitor for Welding Stainless Steel

Measuring the oxygen level with a Weld Purge Monitor® before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds that are metallurgically sound. It is important not to use “oxygen analyzers” or “oxygen safety monitors” as they are calibrated for accuracy only at ambient conditions. The low cost, hand […]

Purge Monitor for clean, oxide free, zero colour welds

Using a purge monitor when welding stainless steel will help to ensure welds are free from oxidation. Welding with a purge monitor. Welding in an environment where the oxygen level is above 100 parts per million (ppm) could cause weld defects, that could lead to a loss of corrosion resistance. Welds could also be rejected […]

Inflatable Welding Enclosures provide low cost Argon Gas Shielding Environment

Welding applications within industries such as the Aerospace, Additive Manufacturing and F1 Racing as well as Medical, Pharmaceutical, Semiconductors and any other company that needs super clean welding joints, have a requirement of absolute cleanliness and smoothness of surfaces, ensuring each weld is mechanically stable and free from oxidation. Titanium is often the metal of […]

Low Cost Weld Purge Barrier for a wide range of Pipe Sizes

Weld Purging various sizes of tubes and pipes at a low cost can be challenging. Many welders today continue to construct their own dams to cut costs. Homemade dams made from material such as foam, sponge or paper can often lead to loss of welds when they leak or slip from position thus flooding the […]

Cost Effective Pipe Repairs with Accu-Freeze™

When making repairs to pipes, for example changing valves, it is common to have to drain down the entire system before the repairs can be made, which can lead to high disposal costs, loss of product and cost of time spent draining and disposing of the product. To dramatically reduce these costs Accu-Freeze™ is available […]
