WTh20

2% thoriated tungsten electrodes (AWS classification EWTh-2) contain a minimum of 97.30% tungsten and 1.70 to 2.20% thorium. They are the most commonly used electrodes today and are preferred for their longevity and ease of use. Thorium increases the electron emission qualities of the electrode, which improves arc starts and allows for a higher current carrying capacity. This electrode operates far below its melting temperature, which results in a considerably lower rate of consumption and eliminates arc wandering for greater stability.

WCe20

2% ceriated tungsten electrodes (AWS classification EWCe-2) contain a minimum of 97.30% tungsten and 1.80 to 2.20% cerium. These electrodes perform best in DC welding at low current settings but can be used proficiently in AC or DC processes. With its excellent arc starts at low amperages, ceriated tungsten has become popular in such applications as orbital tube and pipe manufacturing, thin sheet metal work or jobs where small and delicate parts are welded. Like thorium, it is best used to weld carbon and stainless steels, nickel alloys and titanium, making it an obvious replacement for 2% thoriated electrodes.

WLa20

2% lanthanated tungsten electrodes (AWS classification EWLa-2.0) have excellent arc starting, low-burn-off rate, good arc stability and excellent re-ignition characteristics—many of the same advantages as ceriated electrodes. 2.0% lanthanated electrodes also closely resemble the conductivity characteristics of 2% thoriated tungsten, meaning, in some cases, it can replace 2% thoriated without having to make significant welding program changes. 1.5% lanthanated tungsten electrodes are ideal if you want to optimize your welding capabilities. Lanthanated electrodes work well on AC or DC electrode negative with a pointed end or they can be balled for use with AC sine wave power sources. The lanthana is dispersed evenly throughout the entire length of the electrode during manufacturing.

Note: called E3 in some country.

Compound tungsten electrode is also known as three elements of rare earth. It is a non-radiation material. It is good to balance the electron mobility and evaporation rates, making tungsten electrodes to maximize their performances.

WX tungsten electrode tip burning significantly better than other tungsten electrodes. As three kinds of doping the oxide mixture in the electrode. It’s strict with the production process and the cost of production is more expensive.

Pure tungsten electrode is the earliest use of electrodes in TIG welding. It contains tungsten content minimum 99.5%, without other impurities.

Pure tungsten electrode is only as welding electrode under the condition of AC or resistance welding electrode. It can clean surface of base metal, welded ball become tapering when heating. This shape provides a good and balanced wave form for AC welding.
Pure tungsten electrode has a very high electron output, low vapor pressure, low resistance, good conductivity, thermal expansion, high elastic modulus bright. Therefore, stable arc at low currents, even as low below the 5A. It also does the welding aluminum, magnesium and other.
