Gas tungsten Arc Welding(GATW)

   Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes.

  Tungsten electrodes are available in a range of sizes and lengths and are made up of either pure tungsten or an alloy of tungsten and other rare-earth elements and oxides. Choosing an electrode depends on the base material type and thickness and whether you weld with alternating current (AC) or direct current (DC).

  Each electrode is colour-coded at the tip to eliminate confusion over its type. Unlike the red-tipped thoriated Tungsten electrode, which contain 2% thoria, SHAANXI YUHENG’s blue-tipped multistrike Tungsten electrodes contain a mix of non-radioactive rare earth elements, eliminating the risk to health posed by thoriated Tungsten electrodes.

  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.

  Other tungsten electrodes work at higher temperatures so their oxide additions (mostly radioactive) burn out, or evaporate much faster than those non-radioactive ingredients in MultiStrike, so much so that they give at least 10 times more arc striking capacity of other tungsten electrodes, when tested under the same conditions.

  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.
