This article is mainly about tungsten electrode comparison on their features, including cerium tungsten electrode, yttrium tungsten electrode and compound rare earth tungsten electrode. Their comparison is shown as following.
Cerium tungsten electrode
Grade - WCe10/ WCe15/ WCe20 (adding CeO2)
Features – Cerium tungsten electrode doesn’t have radioactivity and it is environment - friendly. Under low current circumstances, it is easier to arcing and can maintain at low arc current. It is suitable for the pipelines and small components welding, including discontinuous welding.
Yttrium tungsten electrode
Grade - WY20 (add Y2O3)
Features – Yttrium tungsten electrode has no radioactive. It has slim and longer arc beam with high compression; under medium and high current conditions, it has deeper burning groove.
Compound rare earth tungsten electrode
Grade – WMX (addictive is MOx)
Features –Yttrium tungsten electrode is a compound of several (more than two) rare earth oxide; each kind of additive will improve performance of tungsten electrode to a better degree.

There are some common and different points of tungsten electrodes(such as, pure tungsten electrode,lanthanum tungsten electrode and thorium tungsten electrode) showing in this article, and that is comparison.
Type and their comparison can be seen as below:
Pure tungsten electrode
Grade – WP
Features – Pure tungsten electrode is non-radioactive and suitable for AC welding of magnesium, aluminum and their alloy.
Lanthanum tungsten electrode
Grade - WLa10/ WLa15/WLa20
Features – Lanthanum tungsten electrode is also non-radioactive which owns the following features: high current carrying capacity; minimum ratio of burnt area; nice welding capacity; excellent electric conductivity. It is a substitute for thoriated tungsten electrode and mainly applied in DC welding.
Thorium tungsten electrode
Grade - WTh10/ WTh20
Features – Thorium tungsten electrode has excellent electron emission and other good performances, which also owns high current carrying capacity and is suitable for DC welding of stainless steel, carbon steel, nickel and titanium alloy as well. But it has radioactivity that will harm people’s health, so when exposed to it, you should wear protective clothing.

Pure tungsten electrode is one of the types of tungsten electrodes. When compared with other types of tungsten electrodes, such as, thoriated tungsten electrode and lanthanum tungsten electrode, it can show their commons and differences. There are some points comparing in this article, such as, grade, color sign, surface and so on.

The size of sand grain has obvious influence on the abrasion of nozzle. When the grain is small and its kinetic energy is also small so that the impact to nozzle material will be small and has elastic deformation. When the sand grain size exceeds a certain range, material impact is enough to cause fracture. If the size of grain increases further, the nozzle material is also cut deeper, the abrasion is more serious. But when the particle size increases to a certain degree, "size effect" will occur. This is due to the force area material will also increase, the material wear size increases with increases slowly. In addition, the shape of grain will affect the abrasion. The smoother shape of the grain (form factor＜1), the slighter abrasion.
