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 foam, wood etc. all contain water […]

Burry Port RFC Blacks Secure Vital Win

Burry Port RFC travelled to Mumbles RFC for a game many were calling a must win for both sides. Burry Port RFC were buoyed by the return of Club Captain Andy Frances after a lengthy time out with injury since the 1st game of the season. Both teams knew how important this game was but it was […]

Oxygen Monitoring provides high quality and lowest cost Welds

Oxygen monitoring with a Weld Purge Monitor are essential instruments to help obtain zero colour welds by monitoring the oxygen level when welding, where a high quality weld is important. By striving for oxygen free welds, companies can eliminate the post weld cleaning costs, which can be very high making the cost of each weld […]

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 temperature resistant glass fibre tape supports weld […]

Weld Purge Monitors ®

Weld Purge Monitors for Stainless and Duplex Steels, Corrosion Resistant Alloys, Titanium and Exotic Metals Introduction: Weld Purge Monitors ® can ensure that you get the best possible environment to carry out high quality welding of those metals mentioned above. It is essential to measure and monitor oxygen content when welding, so that the welds […]

Fast, Reliable and Safe Stopping of Pipe Contents with Inflatable Rubber Plugs

Sealing, stopping and blocking pipes where oils, hydrocarbons and petrochemicals are present can cause major inconveniences with many normal stoppers not being able to handle such conditions. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® manufactures a Range of Inflatable Rubber Plugs for heavy-duty applications where pipes might contain liquids and gases that usual Inflatable […]

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 Purging Experts Huntingdon Fusion Techniques HFT® […]

Foam Sponge in Weld Purging

The use of foam sponge in Weld Purging is a popular choice for Welders today, but to achieve the highest quality of welds, other materials are better suited. Foam sponge in Weld Purging is widely used. To those people welding stainless steel for garden gates or other decorative applications, satisfactory is something where oxide discolouration […]

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 replacement enormously, Qwik-Freezer™ is available from […]

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 the weld and heat affected zone […]

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 completely fill pipework with expensive inert gas, so weld purging […]

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 rejected, often leading to a significant loss in time and resources. The […]
