Low Cost Weld Purge Monitor® for Stainless Steel Welding

Measuring the oxygen level before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds. During stainless steel welding, the oxygen content must be purged down to a level as low as 100 ppm. The low cost, hand held, battery operated PurgEye® 100, designed and developed by Huntingdon Fusion Techniques […]

Weld Purge Dams for Dished Ends and Short Pipes

Weld Purging (back purging) describes the removal of oxygen from the vicinity of a weld before, during and after welding. For pipe and tank welding of stainless steels, titanium and chrome steels, it is good practice to restrict the area required to be purged, usually with an inflatable tandem weld purging system. For the purging […]

Inert Gas Welding Monitor

Prior to inert gas welding (weld purging), the oxygen content must be reduced (purged) to a level as low as 100 ppm for stainless steels and as low as 50 ppm for zirconium and titanium. When oxygen levels are too high, the parent materials will suffer from a loss of corrosion resistance and metallurgical imperfections. […]

Freeze it and make your pipe repair easy with Accu-Freeze™

Repairs and maintenance work required on tubes and pipes can cause unforeseen costs, with entire systems having to be drained down to ensure no liquids are present when repairs are made. To dramatically reduce operating costs, the Pipestoppers® Division of Huntingdon Fusion Techniques HFT® introduced Accu-Freeze™, the liquid nitrogen (LN2) Pipe Freezing System to create […]

Weld Backing Tape® saves grinding time and costs

When the undersides of welds are ragged and uneven, they often need grinding to smooth them out. This costs labour time and money for grinding materials. The use of Argweld® fiberglass Backing Tape® can save these costs by leaving a smooth fully penetrating, clean weld that needs no further work. Weld Purging Experts Huntingdon Fusion […]

Construction Site Weld Purge Monitor®

There are considerable challenges when working on constructions sites, particularly when the conditions are in the open air. Taking into account global conditions, there might be extreme heat or extreme cold, sandstorms, dust storms, rain storms and winds. All conditions have their own difficulties for expensive equipment and quality results. Because of the extreme variations […]

Zero colour oxide free welds for manual welders

Titanium, stainless steel and other corrosion resistant materials need to be shielded with an inert gas while welding takes place, in order to protect the molten weld pool from combining with oxygen and nitrogen from the surrounding air. Without this protection, welds will oxidise and can form metallurgical defects that may cause weld joint failure. […]

TIG (GTAW) welders need certainty with their welding equipment

One key to a good TIG weld is the electrode. At this time, welders are going through a period of uncertainty as far as the information and circumstances arising with respect to their electrodes. Until now, the best scientifically confirmed electrode was made with Tungsten, with a small addition of a material called thorium oxide, […]

Faster pipe purging with QuickPurge®

When stainless steel, duplex steels or titanium pipes need to be welded in the process industries, they generally have to be purged of air and water vapour, in order to obtain the quality of weld demanded by such industries. Even today, more than 40 years after high quality pipe weld systems were developed, welders are […]

Handy Oxygen Measuring Instruments for Welders

Welders need to measure oxygen near the weld when they are joining metals like titanium, stainless, chrome and duplex steels. A fast and reliable way to do this, is to use a hand held monitor near the joint to ‘sniff’ samples of the gas and to check the amount of oxygen present. Ordinary oxygen monitors […]

New Tungsten Electrode Grinder

Ensuring your Tungsten Electrode is sharpened correctly can help to improve weld quality. Tungsten Electrode Grinders are a convenient, safer and more accurate way than other methods of grinding Tungsten Electrodes. Back by popular demand, Huntingdon Fusion Techniques HFT® have re-initiated the manufacturing of the TEG-2 Tungsten Electrode Grinder, which was retired from their product […]

Flexible Welding Enclosures® for Additive Manufacturing

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. After more than 40 years of experience in the field of manufacturing Flexible Welding Enclosures®, Huntingdon […]
