Weld purge monitoring: Do it remotely

10 February 2021

The exposure to oxygen during the welding process on alloys such as stainless steel will result in discoloration and can severely reduce corrosion resistance properties. It is therefore crucial that the oxygen level is monitored throughout the welding process and kept to a desired level. 

However, is often difficult for welding personnel to get an accurate reading of the oxygen level at the welding zone when welding lengths of tube and pipework of 20 meters length and more.

Huntingdon Fusion Techniques HFT®, a global Weld Purging Products Manufacturer, has created the PurgEye® 1000 Weld Purge Monitor®, enabling operators to read the weld purge gas level from a distance for the first time. 

The PurgEye® 1000 now features 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™ which indicates rising or falling purge levels.

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 color welds are required time after time.
