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 ...

Weld Purging: Replace Paper, Foam and other unsuitable Materials with Argweld® Weld Purge Dams

Weld Purging is essential when welding tubes and pipes made of reactive metals such as stainless steels, titanium and zirconium. Usually weld zones are confined with purge dams so that the use of argon purge gas is limited and waiting times are reduced. Homemade dams fabricated from paper, sponge ...

Oxidation Free Weld Beads with Weld Backing Tape™

Welders are often faced with challenges where high quality stainless steel, duplex and chrome steel welds are required, but where the use of purge gas is not always possible. One solution to this problem is the use of Argweld® Weld Backing Tape™ from Huntingdon Fusion Techniques HFT®. This high te ...

Long Distance Weld Purge Monitoring

Often when welding lengths of tubes and pipework fabrications of 20 metres or more, measuring the purge gas might not always easy. Under these conditions, there is a risk of contamination of the gas exiting the weld zone, leaving the welders uncertain about their welds and welding procedure.  Weld ...

Pipe Freezing with Qwik-Freezer™

Repairs or modifications on pipes can pose challenges, especially where there is liquid present inside, which may result in the expense and danger of system down time and loss of revenue while the system is drained and refilled. To dramatically reduce these costs and speed up the repair or replace ...

Welding Titanium with the Low Cost ‘Nano’

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 million (ppm). Weld Purging in this environment will avoid discolouration of ...

Large Diameter Pipework Fabrications

Large diameter pipework can cause several challenges, especially when those pipes are manufactured from stainless, duplex and chrome steels, titanium or zirconium. When welding such reactive materials, they need to be purged of oxygen before, during and after welding. It is not cost effective to c ...

Supplementary Gas Shielding with an Argweld® Weld Trailing Shield

Eliminating oxidation and discolouration when welding stainless and duplex steels as well as titanium, zirconium and nickel alloys is crucial in many industries today, because of improving quality control procedures. Welds have to be free from metallurgical defects otherwise they can potentially be ...

Weld Purge your Heat-Treated Pipes with HotPurge®

New power plants are in high demand and several hundred are expected to be built over the next decade. Chromium-molybdenum (chromoly) steel pipe such as P91 is a major construction material for the high pressure piping in these plants and there are particular techniques for welding this pipework to ...

Low Cost Weld Purging with Weld Purge Plugs™

Weld Purging smaller tubes and pipes of different diameters can be challenging, especially when budgets are tight. Often, Welders are left to create their own homemade purging dams out of unsuitable materials such as foam, paper or cardboard. Huntingdon Fusion Techniques HFT® have designed and dev ...

Highly Accurate 100 ppm Weld Purge Monitor for Welding Stainless Steel

Measuring the oxygen level with a Weld Purge Monitor® before, during and after welding stainless steel is crucial to achieve oxide free, zero colour welds that are metallurgically sound. It is important not to use “oxygen analyzers” or “oxygen safety monitors” as they are calibrated for accuracy on ...

Standard and Custom Made, Low Cost Weld Purge Dams

When welding stainless steel, titanium or zirconium pipes, or pipework, the oxygen level within the pipe must be reduced to a level of 50 ppm, or lower in certain cases. The most cost-effective solution is to restrict the volume around the joint with a Tandem Weld Purging System. For the purging o ...

Low Cost 1 PPM Weld Purge Monitor®

For many years, oxygen monitors and gas analysers have been used for weld purging. These instruments have been designed and calibrated for accuracy at atmospheric oxygen level, but not for weld purging where accuracy is required when reading much lower oxygen levels. With their scientific backgroun ...

Highest Quality Welds made with Lower Costs

Welding stainless steel, titanium, zirconium, niobium and other metals sensitive to atmospheric gases, requires oxygen levels to be as low as 10 ppm and in some cases, knowledge of dew point level in the shielding and purging gas. Many welds of this nature are still welded with archaic or home-made ...
