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 purged down to under 100 ppm before, during and after welding, which can cause some difficulties in long pipelines. 

Celebrating their 45th Anniversary in 2020 as International Leaders in Weld Purging, Huntingdon Fusion Techniques HFT®'s PurgEye® 1000 Distance Weld Monitor now makes it possible to have an immediate reading for the weld purge zone up to 1,000 metres away. 

Luke Keane, Technical Sales Manager for HFT® said: “If exhaust gas from a normal weld purge system is piped down a hose to a distant measuring instrument, it may take many minutes, or even hours in some cases, to reach the sensor. The exhaust gas may even be contaminated on the way by outgassing from the walls of the hose material or from air drawn in through a leaky connection.”

“The PurgEye® 1000 Weld Purge Monitor® has been designed and developed specifically to overcome such difficulties and has a sensor placed immediately next to the weld purge site with electrical connection to monitoring equipment. This way, the operator can be certain that the weld purge reading is correct and that the joint will not be adversely affected by oxidation, allowing welders to achieve that sought-after zero colour weld without loss of corrosion resistance.” 

With a unique stainless steel sensing head that can be fitted onto any Pipe Weld Purging System or simply left in the welding zone, the PurgEye® 1000 can measure oxygen levels up to 1 km away.

The PurgEye® 1000 is one of HFT®'s five Weld Purge Monitors® to now feature PurgeNet™, a networking device designed for communicating the current oxygen reading from the Monitor, to another piece of equipment, such as the visual warning accessory PurgeAlarm™ or a Dew Point Monitor with additional inter-pass temperature monitoring. 

The PurgEye® 1000 measures oxygen levels from 1,000 parts per million (ppm), right down to 1 ppm (accurate to 10 ppm), ideal for welding metals such as stainless steels, duplex steels, titanium and zirconium where oxide free, zero colour welds are required time after time.

Low Cost Monitor for Welding Titanium and Stainless Steel

Titanium and stainless steel are both reactive alloys. When they are heated during the welding process, they will react with any air that is present, causing oxidation, which can lead to a loss of corrosion resistance properties. Shielding the metal with an inert gas is therefore crucial and one wa ...

Accurately Measure the Dew Point During Purging

During purging welders need to measure the oxygen content but also need to measure the ‘dew point'. The dewpoint is the temperature where condensation begins and water will condense on the material being welded. This can affect the weld properties significantly. Georgia Gascoyne, CEO for HFT® sai ...

Pipe Purging Monitor

What is Weld Purging? Weld Purging is the displacement of oxygen by an inert gas (usually argon) from the vicinity of a weld, before, during and after welding. It is crucial to displace the oxygen when welding many metals to help achieve oxide free, zero colour welds with no loss of corrosion resis ...

Reliable Oxygen Analyzer for Welding Titanium

When welding titanium, it is essential that the oxygen level surrounding the weld is purged down to as low as 50 ppm. Measuring the oxygen level with a reliable oxygen analyzer is the most efficient way to know exactly when to commence welding. Specifically designed for Purge Chamber welding, the ...
