Lanthanum Tungsten Electrode - Ⅱ

Today, lanthanum tungsten electrode is the world's most popular tungsten electrode materials, particularly lanthanum oxide content of 1.5% lanthanum tungsten electrode, which is different from the content of 2.0% lanthanum tungsten electrode. Studies have shown that, the conductive properties of lanthanum tungsten electrode (1.5% of La₂O₃ content) is closest to thorium tungsten electrode (2.0% of ThO₂ content), so welders can replace the electrode, without the need to change the parameters of the device.

In 1998, an experiment showed that: 1.5% La₂O₃ lanthanum tungsten electrode has excellent welding performance and a smaller burn rate; it can be used for AC welding, and has excellent performance.

Experiment
Materials: 2.0% CeO₂ of cerium tungsten electrode; 2.0%ThO₂ of lanthanum tungsten electrode; 1.5% La₂O₃ of lanthanum tungsten electrode.
Procedure: Respectively placing them under the current of 70A and 150A conditions, and under 300V DC environment, to carry out the welding experiment.

Advantages of lanthanum tungsten electrode
1. With good creep resistance properties;
2. With higher recrystallization temperature;
3. With Excellent ductility;
4. With better mechanical cutting properties and so on.
