Lanthanum -Tungsten Electrode is well known for its good welding performance .It is the electrode added with 1-2% of La2O3.The power of its electronic transgression is  2.7-2.8ev ,bearing the closest features to those of the  Thorium - Tungsten Electrode. Its arc features and burn spoilage endurance used with small and medium currents.

2% Lanthanated Tungsten electrodes contains 2% Lanthanum oxide (LaO 3 ) that is also a non-radioactive material. It has good welding performance. Its electric conductivity is closed to that of the 2% thoriated Tungsten electrodes. Lanthanated electrodes operate at a slightly different arc voltage than Thoriated or Ceriated electrodes. Were developed around the same time as Ceriated Tungsten to help combat the increasing awareness of the radioactivity of Thoriated Tungsten electrodes.

Specification:

1.Dia: 0.5-25mm

2.Length: 150mm, 175mm, 178mm, other length as customer required.

Feature: 

Lanthanum-Tungsten Electrode is the substitution product of thorium-tungsten electrode because of its non-radiation. Its other advantage is its endurance of high current and low burn spoilage rate.

Application:

Generally used to weld carbon & stainless steels, nickel alloys and titanium.

Working Parameters:
