Pipe Purging accurately down to 10 ppm

Measuring the oxygen level during Pipe Purging is crucial. Stainless steel has to be monitored down to at least 100 ppm, however alloys such as titanium and zirconium may need to be monitored down to as low as 10 ppm. Pipe Purging Experts Huntingdon Fusion Techniques HFT®'s PurgEye® 200 Weld Purge ...

Successful Low Cost Weld Purging

Weld Purging is the act of removing oxygen from the vicinity of a joint before, during and after welding. Metals that require weld purging include stainless steels, titanium and zirconium. Weld Purging various sizes of tubes and pipes can be challenging as well as expensive, which is why many weld ...

Oxide Free Titanium Welds with the PurgEye® Desk

The Welding Institute states that “Titanium is a reactive metal; it will burn in pure oxygen at 600°C and in nitrogen at around 800°C. Oxygen and nitrogen will also diffuse into titanium at temperatures above 400°C raising the tensile strength but embrittling the metal. Despite this reactivity tita ...

Low Cost Weld Purge Plugs for Tube and Pipe Weld Purging

Due to tight budgets, welders sometimes have to construct their own Weld Purging Equipment, often made from materials such as paper, card, sponge or foam. Homemade dams made from such materials can often lead to loss of welds when they leak or slip from position thus flooding the welding zone with ...

Low Cost Weld Purge Monitor for Welding Titanium

Weld Purging Techniques are now used in most industries especially when welding reactive metals. Whilst the welding torch provides a protective cover to the top of the fusion zone, inert gas coverage is also required at the weld root.  By sampling the gas and testing the oxygen content around the ...

Weld Purging: Replace Foam with Film for High Quality Welds

The use of home made sponge foam purge dams for pipe weld purging is still very familiar throughout the welding industry. However, operators are unaware as to how the use of sponge foam can adversely influence the metallurgical strength of a joint. When sponge foam starts to warm up from the heat ...

Zero Colour Titanium Welds with the PurgEye® Desk

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 ...

New: Unique 10 ppm Colour Touch Screen Weld Purge Monitor®

It is essential to monitor the oxygen level when welding reactive metals. Metals that are classed as ‘reactive' (titanium, zirconium and nickel alloys) are sensitive to oxygen when heated. When welding these metals, the oxygen must be purged from the welding zone, down to as low as 10 parts per mil ...

Weld Purging Post Weld Heat Treated (PWHT) Pipework

Welding processes can weaken metals by imparting residual stresses into a material, leading to a reduction in corrosion resistance properties. Post Weld Heat Treatment (PWHT) is regularly used to retain the strength of a metal when welding certain materials including high strength stainless steel a ...
