When titanium and stainless are heated during the pipe welding process they will react with any air that is present causing oxidation.
This can lead to a loss of corrosion resistance properties so shielding the metal with an inert gas is crucial and one way to measure the oxygen content within the welding zone is by using a weld purge monitor.
Leading the way in this technology, Huntingdon Fusion Techniques HFT’s PurgEye Nano is ideal for welding titanium and high end stainless steel, where oxygen levels are required to be as low as 10 ppm.
Luke Keane, technical sales manager for HFT, said: “By knowing the exact level of oxygen inside the pipe at all times, the welder knows when to start welding for high quality results.
“The PurgEye Nano is our basic entry level 10 ppm monitor, which means it is perfect for restricted budgets. It’s a simple plug and play monitor, ideal for welding titanium, stainless steel and other reactive metals such as zirconium.”
With leak-tight connectors for weld purge hoses, the lightweight device can be used with optional accessory hand pump and gas sampling probe.
The PurgEye Nano has been developed for weld purging where data logging, alarms and machine control are not necessarily required. The monitor has been developed with a unique long life sensor that has a warm up time under 60 seconds.
Ron Sewell, chairman of HFT, added: “All of our weld purge monitors and inflatable tube, pipe and pipeline weld purging systems as well as our inflatable welding enclosures are manufactured in the UK. We do not sacrifice on quality and guarantee 100% craftsmanship.”
