Titanium is the metal of choice in a variety of industries due to its excellent corrosion resistance to acids, chlorides and salt. Titanium has a wide continuous service temperature range, from liquid nitrogen (-322°F) to 1,100°F and the highest strength-to-weight ratio of any metal.
Titanium is a reactive metal, so when heated it will react with surrounding oxygen, discolour and lose its corrosion resistance properties. In critical welding applications, it is therefore crucial that the oxygen level surrounding the weld is purged of oxygen to 50 ppm or lower.
The innovative PurgEye® Desk, a new Weld Purge Monitor® designed and manufactured by weld purging experts Huntingdon Fusion Techniques HFT®, is leading the way in inert gas purging technology by reading oxygen levels from 1,000 ppm, right down to levels as low as 1ppm (highly accurate to 10 ppm), ensuring titanium welders achieve perfect oxide free, zero colour welds time and time again.
Ron Sewell, Chairman for HFT® said: “Titanium parts are often welded inside a welding enclosure, where the entire atmosphere surrounding the weld can be kept at a controlled level of oxygen. The PurgEye® Desk is ideal for use with Welding Chambers, cabinets and flexible enclosures, as well as with Orbital Welding Machines and other Automatic Welding Systems.”
The PurgEye® Desk is manufactured with HFT®'s 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.
The rugged, high frequency proof PurgEye® Desk 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, the PurgEye® Desk Weld Purge Monitor® 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 the welding systems.
Applications for the PurgEye® Desk can be found in ultra clean conditions, such as in cryogenics, food, drinks, semi-conductor, aerospace, pharmaceutical sectors as well as other industries where titanium is used for its light weight, strength and high strength-to-weight ratio.
