For quite some time, tungsten manufacturers have added an oxide to pure tungsten to improve the arc starting characteristics and the longevity of welding electrodes. While 2% thoriated tungsten has been the most commonly used tungsten material for many years, this electrode type is increasingly being scrutinized because of concerns for the ...
Tungsten electrodes are classified on the basis of their chemical compositions: E stands for electrode, which is used for one terminal of the arc welding circuit W stands for the chemical symbol of tungsten. The final letters indie the alloying element (oxide additions): P designates a pure tungsten electrode without alloying elements

Pure tungsten electrodes contain percent tungsten, have the highest consumption rate of all electrodes, and typically are less expensive than their alloyed counterparts. These electrodes form a clean, balled tip when heated and provide great arc stability for AC welding with a balanced wave.
Mar 19, 2018 · The original green pure tungsten electrode contains at least % tungsten and delivers all of the properties classically associated with tungsten – superior conductivity, durability, and performance. Green electrodes are perfect for weld projects containing magnesium alloys .
Aug 20, 2009 · Pure tungsten electrodes (AWS classifiion EWP) contain % tungsten, have the highest consumption rate of all electrodes and are typically less expensive than "alloyed" counterparts. These electrodes form a clean, balled tip when heated and provide good arc stability for AC welding with a balanced waveform.
Aug 25, 2021 · Pure tungsten electrodes or Rare tungsten electrodes are liked for AC sine wave welding of aluminum and magnesium since they furnish great bend dependability with both argon and helium protecting gas. The rare tungsten terminal effectively frames a balled end yet tends to spit at higher flows, and this ought to be viewed when making basic welds.
The electron work function of tungstenlanthanum oxide is significantly lower than that of pure tungsten. Consequently, WL is a popular choice for ion sources, lamp electrodes and welding electrodes. WLS (TungstenLanthanum OxideStem).
Electrode Materials. Evolving from our vast experience working with engineers and technical teams to perfect the art and science of automated micro spot welding appliions, Metal Cutting offers a range of specialty refractory metal electrode products, including copper tungsten electrodes, silver tungsten electrodes, and pure tungsten electrodes.
Sep 18, 2019 · Pure tungsten electrodes are % tungsten, and that gives them the capability to ball or round easily. The ball tip shape is what makes the electrodes good with arc stability. Pure tungsten is also suitable for appliion of low to medium amperages with magnesium and aluminium alloys. Pure tungstens are cheap but are rarely used in the industry.
Feb 21, 2006 ·, 05:08 AM. Ben. I think the biggest difference I can see is as you noted, the ceriated doesn't seem to get contaminated as easily as the thoriated or pure. If you touch the pure tungsten to aluminum you're not going to continue until you replace the tungsten whereas with the cer, zirc, or lanth tungsten, you can still maintain an arc ...
Thoriated tungsten electrodes contain % pure tungsten and % thorium oxide, which has low radioactivity. The increased current carrying ability of thoriated tungsten electrodes is one reason it suits arc welding. The electrodes are easy to use and last a long time, which offers added advantages.
However, pure singlecrystalline tungsten is more ductile and can be cut with a hardsteel hacksaw. Tungsten occurs in many alloys, which have numerous appliions, including incandescent light bulb filaments, Xray tubes, electrodes in gas tungsten arc welding, superalloys, and radiation shielding.
