Lanthanated Tungsten Electrodes

As we all know, the most common lanthanated tungsten electrodes contain lanthanum dioxide (La2O3). Nowadays thoriated tungsten electrodes usually be are replaced by lanthanated tungsten electrodes in most applications. There are three types of lanthanated tungsten electrodes: 2% lanthanated tungsten electrodes, 1.5% lanthanated tungsten electrodes and 1% lanthanated tungsten electrodes. After testing the 2% lanthanated tungsten electrodes, we find that the using life of lanthanated tungsten electrodes is longer than thoriated tungsten electrodes if there’s no overload current. And it is easier to start arc in most applications than thoriated tungsten electrode.

The lanthanum containing in lanthanated tungsten electrodes belongs to rare earth and it is not radioactive. The lanthanated tungsten electrodes is mainly used for DC welding. And the using effect in AC welding is also good.

The conductivity of 1.5% lanthanated tungsten electrodes is the most nearest with the properties of 2% thoriated tungsten electrodes. So the welder can easily replace the electrode and do not need to change the parameters of the devices.
