Indutrade UK has recently announced the acquisition of Huntingdon Fusion Techniques HFT®. HFT® will become part of the ALH Systems Group and will continue to...

Weld Purging Experts Huntingdon Fusion Techniques HFT®’s innovative QuickPurge® Systems, which are manufactured up to 88″ (2,235mm), dramatically reduces the space that needs to be purged, thereby reducing purging time dramatically, making huge savings in both time and gas costs.

Innovators in Weld Purging Huntingdon Fusion Techniques HFT® have recently developed a Dew Point Sensor, an important predication instrument of when water will form on metal surfaces in the welding environment.

Whilst welders generally are highly skilled in their own disciplines, there are some aspects of metal joining where a clear understanding is limited. Metals and the effects of welding on their properties, the importance of cleaning and protection against oxidation are only some examples where additional knowledge is often required.

Weld Purging large diameter pipework made from stainless, duplex and chrome steels, titanium or zirconium can be expensive, with requirements to have the oxygen level well below 100 ppm during the welding cycle.

The low cost, handheld, battery operated PurgEye® 100, designed and developed by Huntingdon Fusion Techniques HFT® is perfect for obtaining zero color, oxide-free welds in stainless steel, reading accurately from atmospheric oxygen level (20.94%), right down to 100 ppm (0.01%).

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.

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.

When welding titanium and any other reactive metal for additive manufacturing, it is important that the welding zone is purged of oxygen and nitrogen to a level as low as 10 parts per million (ppm) of O2 or less.
