Weld Purging is the act of removing oxygen from the vicinity of a weld before, during and after welding metals such as stainless steel, titanium, zirconium and nickel alloys. Without Weld Purging, the weld would be left oxidised and discoloured, which could then lead to loss of corrosion resistance and metallurgical imperfections.
In order to accurately read the residual oxygen level inside a tube, pipe, welding chamber or enclosure during the act of purging, a Family Range of Weld Purge Monitors is available in the USA from COB Industries to suit all applications and budgets. The PurgEye® Desk launched this month, is ideal for use with Welding Chambers and Enclosures as well as Orbital Welding Machines and other Automatic Welding Systems.
COB Industries said: “The PurgEye® Desk replaces the old PurgEye® 500, but with new and innovative features. One huge addition is our revolutionary PurgeNet™, for the in-line connection of several accessories that allows the Weld Purge Monitor® to actually control welding systems based upon oxygen level.”
“PurgeNet™ controls welding power sources such as Orbital Welding Machines and any other Automatic Welding Systems, to switch them on and off according to oxygen levels. PurgeNet™ can be used with the integrated PurgeLog™ Software to transfer weld purge data for quality control of welds. PurgeNet™ connects with other smart accessories for weld purging, one of which is the Visual Purge Alarm which gives an indication during welding in case of rising or falling oxygen levels.”
The PurgEye® Desk has automatic fault finding diagnostics, that can detect and report a number of possible faults and it also features an OLED (organic light emitting diode) display giving brighter, sharper readings at longer distances. This rugged, high frequency proof instrument measures oxygen levels from 1,000 down to 1 ppm (accurate to 10 ppm).
The PurgEye® Desk has a unique, fast response, long-life sensor with little maintenance requirement. The 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.
This Weld Purge Monitor® is particularly suitable for use in ultra clean conditions, such as in cryogenics, food and drinks, semi-conductor, aerospace, pharmaceutical sectors and any other process industries.
