Lanthanated tungsten electrodes

Lanthanated tungsten electrodes is an improved product introduced by European countries in the 1980s to replace tantalum tungsten products. Once introduced, it has attracted much attention and popularity in the international welding industry due to its excellent welding performance, especially sought after by the European Welding Academy. For this reason, the export volume of thoriated tungsten electrodes is second only to thoriated tungsten electrodes, but the recognition in the domestic market is not high. Its characteristic is that the conductive performance is closest to 2% thoriated tungsten electrode, and the durable current is high and the burning rate is the smallest.

Lanthanated tungsten electrodes has the following advantages: 

1. Better mechanical cutting performance 

2. Better creep resistance

3. High recrystallization temperature 

4.  Good ductility. 

Lanthanated tungsten electrodes are currently the most popular electrode materials in the world, especially lanthanated tungsten electrodes with a content of 1.5% (different from 2.0%). Scientific studies have shown that 1.5% lanthanated tungsten electrodes has the conductivity of the nearest 2.0% lanthanated tungsten, so the welder can easily replace the electrode without changing the parameters of the device. In 1998.

There was a well-known professional test in which a 2.0% lanthanated tungsten electrode, a 2.0% lanthanated tungsten electrode, and a 1.5% lanthanated tungsten electrode provided by two manufacturers were respectively operated at 70 amps and 150 amps of current, 300 volts DC. In the case of the welding task, in both cases, the 1.5% lanthanated tungsten electrode exhibits excellent solderability and also exhibits a low burn rate. Moreover, lanthanated tungsten electrode are also suitable for AC welding tasks with excellent performance.

Basic size:

1) Diameter: 0.5-25mm

2) Length: 150mm, 175mm, 178mm, any other required length.

4. Recommended lanthanated tungsten electrode for different welding currents, and we can custormize according to your requiements.
