Why Use Non-Thoriated Tungsten Electrodes

Tungsten Electrodes – Some Specific Background and Science – The work function of a metal or alloy is the energy needed to remove an electron from Fermi level in the material to a point at an infinite distance outside the surface. This is relevant to TIG welding since the lower the work function of an electrode, the lower the voltage necessary to strike an arc. The work function of tungsten is 4.35 ev. Therefore, the addition of a stable metal oxide with a work function lower than pure tungsten, lowers the work function of the tungsten. Thorium’s work function is 3.4 ev. The special blend of dopants in MultiStrike® has a work function of 2.9 ev. Huntingdon Fusion Techniques HFT®’s special blend of dopants along with its stringent in-house production specification ensure that the dopant is distributed evenly through the Techweld® MultiStrike® maintaining an even performance from start to finish.

Non-Radiotoxic TIG Welding Tungsten Electrodes

Huntingdon Fusion MultiStike electrodes consist of a unique blend of dopants to allow them to perform at high, low and medium current ranges with TIG (GTAW) welding of steels, nickel and cobalt based materials, as well as titanium and aluminium alloys. TThis unique blend of dopants greatly enhances electrode life by significantly increasing the number of arc strikes before re-grinding is necessary, generating an up to 10 times better performance from MultiStrike® Tungstens compared with thoriated tungsten electrodes. he carefully balanced mix of non-radiotoxic dopants used in Techweld® MultiStrike® Tungsten Electrodes will give you up to 10 times the number of arc strikes, over conventional 2% thoriated tungsten electrodes under identical conditions. 

Techweld MultiStrike electrodes from Huntingdon Fusion

Highest quality, totally traceable, longest lasting and are the most reliable tungsten electrodes on the market allowing welding of steels and alloys with DC as well as aluminium with AC techniques giving narrower, lower heat input welds. MultiStrike® Tungsten Electrodes produce a 10 times greater number of arc strikes, over conventional thoriated tungsten electrodes under the same conditions and provide a stable performance over the current range from 0 – 300 Amps.

No Radio-Toxic Contents Whether you are an employer who is looking after the Health and Safety of your employees and others, or if you are a welder concerned about the carcinogenic effects of conventional thoriated tungsten electrodes, you may wish to consider the safer alternative, Techweld® MultiStrike® Tungstens (MST). 

MultiStrike Traceability

Special Packaging Guarantees Quality MultiStrike® Tungstens are a trade marked development by Huntingdon Fusion Techniques HFT® and are fully traceable to the original source, giving the user a guarantee of product quality, reliability, repeatability, consistency and traceability. Each batch of 10 is supplied in special packaging and comes with a unique reference number which is your guarantee of quality and traceability. Now you can achieve all of your TIG (GTAW) welding with one tungsten electrode and eliminate the need to stock radiotoxic thoriated products or other doped electrodes containing ceria, lanthana or zirconia. MultiStrike® contain a blend of rare earth dopants to replace Thoria. The dopants are not radioactive and they are mixed in accurate proportions using statistical proportional control procedures, fully computerised to ensure that the tungstens are made to the same high standards every time. 

The exact ingredients are part of the intellectual property of Huntingdon Fusion Techniques HFT® who have carried out extensive research and development to bring a quality product to the market place that is totally traceable, reliable and repeatable. The unique packaging gives a guarantee of product quality, reliability, repeatability, consistency and traceability. MultiStrike® Tungstens conform to the rules and regulations of EN 26848 and ANSI/AWS A5 12m-98.
