Indutrade UK has recently announced the acquisition of Huntingdon Fusion Techniques HFT®. HFT® will become part of the ALH Systems Group and will continue to...

Grade 9 titanium alloy contains 3% aluminum and 2.5% vanadium, less alloying material than the more common Grade 5 (6% aluminum and 4% vanadium).

Weld Purging Experts Huntingdon Fusion Techniques HFT®’s innovative QuickPurge® Systems, which are manufactured up to 88″ (2,235mm), dramatically reduces the space that needs to be purged, thereby reducing purging time dramatically, making huge savings in both time and gas costs.

When welding metals such as stainless steel, titanium and zirconium, it is important to make sure that the welding zone is purged of oxygen even as low as 10 parts per million (ppm) before, during and immediately after welding, in order to achieve a clean, oxide free, zero colour weld. Huntingdon Fusion Techniques HFT® has recently manufactured tailor made Argon Gas Feed Hose assemblies with leak tight fittings to attach immediately to their Argweld® range of Inflatable Tube and Pipe Weld Purging Systems at one end and to the gas source at the other.

When welding titanium, stainless steel and other reactive metal pipework and sheet metalwork, it is important to prevent the welds from oxidising or coming into contact with any air during their welding and cooling periods. Trailing Shields®, designed and manufactured by Huntingdon Fusion Techniques HFT® ensure the weld stays under a protective argon gas coverage, while the hot weld metal is cooling, preventing it from oxidising on contact with air. Photo courtesy of Trailing Shields Titanium and stainless steels are chosen for their corrosion resistant properties and if they are allowed to oxidise during the weld cycle, expensive post welding cleaning techniques are required. Trailing Shield® helps to avoid oxidation and expensive cleaning process. Georgia Gascoyne, CEO at Huntingdon Fusion Techniques HFT® said: “Our range of Trailing Shields® are available in flat format for sheet metal welding or in curved format for welding circular items like tubes, pipes and tanks.

Inert gas purging is vital when welding metal tubes made from titanium, as well as ultra-high purity stainless steel joints and just as important when welding those less critical stainless steel and copper nickel pipe joints, in order to achieve non-oxidized, zero color welds. PurgExtra™ is the latest weld purging product released by Huntingdon Fusion Techniques HFT® for the purging of tube and pipe joints from 1 to 24” diameter.

Huntingdon Fusion Techniques HFT® has reached the fifth version of its Tube and Pipe Weld Purge System designs by launching the new PurgElite® range of Tube and Pipe Weld Purging systems for diameters from 1” to 24” diameter. These systems are suitable for all industries using stainless steel tubes and pipes from highly specialised biogas and semiconductor fields, right along to other industries such as those where the required quality may be less critical. In particular, PurgElite® systems can be used where the internal surfaces may be polished to ensure minimum entrapment and low corrosion resistance.

The latest Titanium Purge Monitor from HFT (Huntingdon Fusion Techniques) incorporates a universal cut-off feature for interlocking with automatic or manual TIG/GTAW welding equipment.
