Tig welding tungsten electrode, you know how to choose? Choose the wrong one, the harm is great!
Tig Welding Yolo Materials Industry 24th, Mar 2023 12:00pm
Due to the characteristics of tungsten, making it very suitable for TIG welding. In tungsten metal, add rare earth oxides, so that the electrode has better arc starting performance, higher stability of the arc column, and smaller electrode burn rate.
Typically, rare earth additives are cerium oxide, lanthanum oxide, zirconium oxide, yttrium oxide and thorium oxide. Therefore, this has many different names for tungsten electrodes, such as thorium tungsten electrode, cerium tungsten electrode and so on.
Here, Frank will give you a brief introduction to the characteristics of various tungsten electrodes.
Rare earth tungsten electrode
Ceriated Tungsten Electrode
Ceriated tungsten is the best alternative to thoriated tungsten electrodes for low current welding environments.
Ceriated tungsten electrodes are mainly used in low current DC welding applications.
Ceriated tungsten has excellent arc starting performance at low currents, making it the standard for most manufacturers of tracked pipe welding equipment.
Lanthanated Tungsten Electrode
Currently, lanthanated tungsten electrodes are the most popular electrode material internationally, especially those with 1.5% Lanthanated Tungsten (as opposed to 2.0%).
Scientific studies have shown that 1.5% lanthanated tungsten has the closest electrical conductivity to 2.0% thoriated tungsten. Therefore, welders can easily change electrodes without changing the parameters of the equipment.
Lanthanated tungsten electrodes are also suitable for AC welding tasks and offer excellent performance.
Zirconiated Tungsten Electrode
Zirconiated tungsten electrodes, like pure tungsten electrodes, can only be used for welding work in an AC environment.
Zirconium tungsten electrodes provide good welding performance in an AC environment. Especially at high load currents, zirconiated tungsten electrodes exhibit superior performance that cannot be replaced by other electrodes.
When welding, the end of zirconiated tungsten electrode can be kept in a round ball shape to reduce tungsten penetration, and has good corrosion resistance.
WX4 Multi-Composite Tungsten Electrode
With its three advantages of “burn resistance, all-round performance and environmental protection”, it has been well received by users! It has really realized the upgrade of tungsten electrode! It is like a sub-healthy patient’s body reaching a healthy state by supplementing with trace elements!
Based on the technology of ternary composite rare-earth tungsten electrode, the tungsten electrode with four rare-earth oxides of lanthanum, cerium, yttrium and zirconium is named WX4, which means it is a quadruple tungsten electrode.
Yolo, by adding 4 rare earth elements with different properties to the tungsten electrode at the same time, they affect and complement each other. This ensures that the electron-emitting capability of the tungsten electrode is stable and sustainable, under any complex conditions.
