Thoriated Tungsten Electrodes contain thoria, a radioactive element that can be dangerous to heath. During the grinding of the electrode there is a generation of radiotoxic dust, with the risk of this being inhaled by the welder.
Welders today continue to use thoriated Tungsten Electrodes. Because thoria was much cheaper than alternative elements to lower the work function of pure tungsten, this type became the industry standard.
To overcome the risk posed by the harmful thoria and whilst maintaining a very high life expectancy for the Tungsten Electrode, Huntingdon Fusion Techniques HFT®’s blue-tipped MultiStrike® Tungsten Electrodes contain a mix of non-radioactive rare earth elements, eliminating the risk to health posed by radioactive thoriated Tungsten Electrodes.
A customer in the UK recently said: "MultiStrikes® are the most consistent Tungsten Electrodes I have used over the past 34 years. I would not use anything else now. I do not think that many people realise how important a good electrode is.”
Other Tungsten Electrodes work at higher temperatures so their oxide additions burn out, or evaporate much faster than those non-radioactive ingredients in MultiStrike®, so much so that MultiStrikes® give at least 10 times more arc striking capacity of other Tungsten Electrodes, when tested under the same conditions.
MultiStrikes® can be used for welding aluminium with the AC process, as well as steels and alloys with the DC process, which allows the welder to have just one type of Tungsten Electrode to weld all materials and reduce the amount of stocks and purchasing requisitions.
With most Tungsten Electrodes in use still containing radioactive and carcinogenic 2% thorium oxide, MultiStrike® provide the TIG and Plasma welder with a safe and superior alternative.
Each packet comes with a traceability number to ensure that companies with a quality control procedure have traceability over another aspect of their joining processes.
