Thoria, found in thoriated Tungsten Electrodes is a radio-toxic compound and emits mainly alpha particles, which are harmful if released inside the digestive tract or inside the lungs where they act as a carcinogen. Thoriated Tungsten Electrodes therefore pose a risk to welders during grinding.
Why are thoriated Tungsten Electrodes still in use today? Welders today continue to use thoriated Tungsten Electrodes as a cheaper alternative to other safer Tungsten Electrodes, often unaware of the risks.
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, whilst maintaining a high performing Tungsten Electrode.
Ron Sewell, Chairman for HFT® said: “Our MultiStrike® Tungsten Electrodes have been developed with the health and safety of the end user in mind. Other Tungsten Electrodes work at higher temperatures so their oxide additions burn out, or evaporate much faster than those non-radio-toxic 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.
HFT®'s unique packaging gives guarantee of product quality, with a traceability number to ensure that companies with a quality control procedure have traceability over another aspect of their joining processes.
