When welding titanium and zirconium joints it is important that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm).

Flexible welding enclosures® for titanium welds

It is important that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm), when welding titanium, zirconium and some stainless steel joints.

New Weld Trailing Shields from HFT

When welding titanium using the GTAW / TIG process, the gas shield from the welding torch needs extending for protection from oxidation and for productivity.

HFT wins award

The Association of Welding Distributors (AWD) announced the winners of their ‘Welding World Awards’ on Wednesday 13th April, at a gala dinner, held at the Hilton Metropole Birmingham.

Nylon Weld Purge Plugs from HFT

Ensuring that the stainless steel tubes and pipes are welded without oxidation, which leads to loss of corrosion resistance, it is vital in industries such as oil and gas, nuclear, food and beverage, pharmaceutical, semiconductor and dairy that in order to achieve a perfect zero color weld, the oxygen level must be purged down to lower than 100 ppm before and during welding.

Argon gas feed hose for weld purging system

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.

PurgEye® 100 by HFT

Weld Purge Monitors® are an essential instrument to help obtain non-oxidised, zero colour welds by monitoring the oxygen content, ideal when purging with inert gas, when welding metals such as stainless steel, titanium and nickel alloy where a high quality weld is required. Advancing in the science of manufacturing beyond other designs, Huntingdon Fusion Techniques HFT®’s market leading PurgEye® 100 helps to eliminate the post weld cleaning costs.

New MultiStrike® Tungsten Electrodes

After having recognised the health hazards posed by the radio toxic red tipped thoriated tungsten electrodes that are widely used in the welding industry, Huntingdon Fusion Techniques HFT® have developed MultiStrike® Tungsten Electrodes that are free from the potentially harmful thoria.

Trailing Shields® offer high quality welds

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.

HFT introduces PurgExtra tube

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.
