Welding Titanium: Tips for Success

Welding Titanium: Techniques for success! Welding Titanium: Titanium is a reactive metal. When it is heated during welding it will react with oxygen that surrounds it, forming oxidised welds, which will lead to loss of corrosion resistance properties. In many industries today, this is no longer acceptable. Oxidised welds will be rejected, causing unnecessary rework. […]

Portable 10 ppm Weld Purge Monitor

With ever-improving standards in Quality Control, measuring the oxygen level around welds before, during and after welding reactive metals is crucial. The hand held PurgEye® 200 is a Weld Purging Monitor® specifically developed and designed for use when welding titanium, zirconium, high specification stainless steel and nickel alloy joints, so that the user can produce […]

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 of the weld, […]

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 reactive metal, so when heated it will react […]

No Draining the Pipe System with Pipe Freezing

Eliminating the need to drain long sections of pipe for repairs or modifications and reducing shut down time is now possible with Pipe Freezing Systems. The Pipestoppers® Division at Huntingdon Fusion Techniques HFT® provides a cost saving solution with Qwik-Freezer™, the industry standard portable CO2 Pipe Freezing System. Ron Sewell, Chairman for HFT® said: “Pipelines […]

Tungsten Electrode Grinder from HFT®

Tungsten Electrode Grinder: The Tungsten Electrode is one of the most important variables involved in TIG welding. Preparing your Tungsten Electrode correctly will help to improve arc starting, arc stability and consequently weld quality. Huntingdon Fusion Techniques HFT® have been manufacturing Tungsten Electrode Grinders since the 1980’s. Just look how far we’ve come… Above is […]

Welding Fume Exposure: HSE Issues Safety Alert

Welding Fume Exposure: The Health and Safety Executive has issued a safety alert as a result of new scientific evidence, which suggests that exposure to welding fume, including mild steel welding fume, can cause lung cancer. In addition, there are warnings about thoriated tungsten electrodes (see below). Bulletin N. STSU1 - 2019 “All businesses undertaking […]

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 million (ppm). Weld Purging in […]

Heavy-Duty Flow and Line Stopping with Steel Plugs

There are occasions where pipes need to be repaired whilst liquids are still flowing. Heavy-duty flow stopping and line plugging may require plugs and stoppers to have long immersion in chemicals or exposure to high temperatures, which many such items are not capable of withstanding. Providing the user with the opportunity to isolate a section […]

Flow Stopping, Blocking and Pipe Weld Purging with Pipestoppers®

Flow stopping and blocking in order to carry out routine maintenance, repair work or even for weld purging is easy with the products from the Pipestoppers® Division of Huntingdon Fusion Techniques HFT®. The Pipestoppers® Division design and manufacture ranges of Mechanical and Inflatable Pipestoppers® as well as Pipe Plugs to suit every diameter and application, […]

Improve Tungsten Electrode and Welding Arc Performance with the TEG-1000

Tungsten Electrode Grinders are essential with TIG/GTA welding. Using a Grinder that has been designed and manufactured specifically for tungsten metal is not only a much safer option, they provide more accurate results leading to as many as ten times greater number of arc strikes and giving very directional arcs without flicker or wander. The […]

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 and chromium-molybdenum (chromoly) steel such as P91. Temperatures during PWHT might […]
