Monitor Your Weld Purge at a Distance


When welding long pipelines, one problem operators often face is not receiving a fast and true weld purge reading from the weld zone.

Huntingdon Fusion Techniques HFT® make it possible to have an immediate reading of the weld purge gas from any distance up to 1,000 metres away with the PurgEye® 1000. 

This unique Weld Purge Monitor® has a stainless steel sensing head that can be fitted onto any Pipe Weld Purging System or simply left in the welding zone and have the oxygen levels transmitted electronically to a monitor up to 1 km 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. 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.” 

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.

Pipe Purging accurately down to 10 ppm

Measuring the oxygen level during Pipe Purging is crucial. Stainless steel has to be monitored down to at least 100 ppm, however alloys such as titanium and zirconium may need to be monitored down to as low as 10 ppm.

Oxide Free Titanium Welds with the PurgEye® Desk

The Welding Institute states that “Titanium is a reactive metal; it will burn in pure oxygen at 600°C and in nitrogen at around 800°C. Oxygen and nitrogen will also diffuse into titanium at temperatures above 400°C raising the tensile strength but embrittling the metal. Despite this reactivity tita ...
