2, Length: 150mm, 175mm
3, We also accept orders of special specification Tungsten electrode.
The cerium tungsten electrode has good starting arc performance under the condition of low current. The arc current is low; therefore the electrodes can be used for welding of pipe, stainless and fine parts. Cerium tungsten electrode the first choice for replacing thoriated tungsten electrode under the condition of low DC.
The Form of Cerium Tungsten Electrode
1. Added impurity: CeO2
2. Impurity quality: 1.8-2.20%
3. Other imputities: <0.20%
4.Tungsten: The rest
5. Electric discharged power: 2.7-2.8
6. Color sign
The electric conductivity of lanthanated tungsten is most closed to that of 2% thoriated tungsten. Welders can easily replace thoriated tungsten Electrode with lanthanated tungsten electrode at either AC or DC and not have to make any welding program changes. Lanthanated Tungsten Electrodes
The Form of Lanthanated Tungsten Electrodes
| Added impurity | Impurity quantity | Other impurities | Tungsten | Electric discharged power | Color sign |
| La2O3 | 0.80 - 1.20% | <0.20% | The rest | 2.6 - 2.7 | Black |
| La2O3 | 1.30 - 1.70% | <0.20% | The rest | 2.8 - 3.0 | Yellow |
| La2O3 | 1.80 - 2.20% | <0.20% | The rest | 2.8 - 3.2 | Sky blue |
The zirconiated tungsten electrode has good performance in AC welding, especially under high load current. Any other electrodes in terms of its excellent performance can not replace zirconiated tungsten electrodes.
The Form of Zirconiated Tungsten Electrodes
| Added impurity | Impurity quantity | Other impurities | Tungsten | Electric discharged power | Color sign |
| ZrO2 | 0.20 - 0.40% | <0.20% | The rest | 2.5 - 3.0 | Brown |
| ZrO2 | 0.70 - 0.90% | <0.20% | The rest | 2.5 - 3.0 | White |
Thoriated tungsten electrode is the most commonly used tungsten electrode, throium is a low-level radioactive material, but it was the first to display a significant improvement over pure tungsten.
The Form of Thoriated Tungsten Electrodes
| Trade mark | ThO2 Content | Color sign |
| WT10 | 0.90 - 1.20 | Primary |
| WT20 | 1.80 - 2.20 | Red |
| WT30 | 2.80 - 3.20 | Purple |
| WT40 | 3.80 - 4.20 | Orange Primary |
Suitable for welding under alternating current;
Mainly applied in military and aviation industry with narrow arc beam, high compressing strength, and highest welding penetration at medium and high current;
