Tungsten Electrodes
WX-2 The Multi-composite Rare-earth Tungsten Welding Electrode
Electrodes with rare earth (mixed oxides). In comparison to thoriated electrodes, WX-2 Composite tungsten electrode is less harmful to the environment and not radioactive. The electrodes offer excellent ignition characteristics and consistent welding properties. Tungsten Welding electrodes are universal and suitable for all applications in the whole range of DC and AC welding for non-alloyed and high-alloyed steel, aluminum, titanium, nickel, copper and magnesium alloys. Because of their great ignition properties they are also suitable for automated welding. Due to the low electrode temperature, they offer an increased current carrying capacity and longer service life than thoriated electrodes.
The performances of Composite Electrodes in welding can be much improved by adding two or more rare earth oxides which are mutually completementary.

- Electrodes with rare earth (mixed oxides). In comparison to thoriated electrodes this electrode is less harmful to the environment and not radioactive.
- Ceriated Tungsten Electrode is a non -radioactive material. It is known to be especially good for DC welding with low amperage because it starts very easily at low amps and usually requires about 10% less amps to operate than thoriated material.
- Pure tungsten electrode, also known as wolfram electrode. It can be manufactured with black surface, polished surface or ground surface.
- 1.5% lanthanum tungsten electrode (Wolfram electrodes), which is also known as WL electrode, contains a minimum of 97.80% tungsten and 1.30 to 1.70% lanthanum
- Yttriated Tungsten is primarily used in military and aviation industry with narrow arc beam,high compressing strength,highest welding penetration at medium and high currentt.
- A zirconiated tungsten electrode produces an extremely stable arc and resists tungsten spitting. It is ideal for AC welding because it retains a balled tip and has a high resistance to contamination. Its current-carrying capability is equal to or greater than that of thoriated tungsten.
- 2% Thoriated tungsten electrode, which is also known as WT electrode, contains a minimum of 97.30% tungsten and 1.70 to 2.20% Thoriated.
