Inert gas welding monitor for aerospace applications

Prior to inert gas welding (weld purging) of titanium, as used widely in the Aerospace Industry, the oxygen content must be reduced (purged) to a level as low as 50 ppm or less (parts per million) for titanium.

When oxygen levels are too high, the parent materials will suffer from a loss of corrosion resistance and the creation of metallurgical imperfections.

The innovative PurgEye Desk, a new monitor designed and manufactured by weld purging experts Huntingdon Fusion Techniques HFT, is leading the way in inert gas weld purging technology by reading oxygen levels from 1,000 ppm, right down to levels as low as 1ppm (highly accurate to10 ppm), ensuring welders achieve perfect oxide free, zero colour welds time and time again.

Ron Sewell, Chairman for HFT said: "The PurgEye desk is for use with Welding Chambers and Enclosures, as well as with Orbital Welding Machines and other Automatic Welding Systems. One huge addition to the PurgEye Desk is our revolutionary PurgeNet, for the in-line connection of additional accessories that allows the Weld Purge Monitor to control welding systems based upon oxygen level as well as to provide indications of high and low oxygen levels and even give dew point measurements."

This rugged, high frequency proof instrument has automatic fault finding diagnostics that can detect and report a number of possible faults. It also features an OLED (organic light emitting diode) display giving brighter, sharper readings at longer distances.

With a unique, fast response, long-life sensor having little maintenance requirement, this instrument comes complete with an integral pump to deliver the exhausting purge gas to the measuring sensor on a consistent basis to allow precision control of welding systems.

The PurgEye Desk is particularly suitable for use in ultra clean conditions as found in most Aerospace applications.
