Lanthanum- tungsten electrode has become the most favored electrode material globally, especially for the type with 1.5% of lanthanated tungsten.
Proven by scientific research, the electric conduction of 1.5% of lanthanated tungsten works as almost efficient as 2.0% of lanthanated tungsten. Therefore, welders are capable of changing electrodes easily instead of adjusting specification of the device.
The year of 1998 witnessed an famous experiment in whicn 2.0% thorium tungsten electrode, 2.0% cerium tungsten electrode and 1.5% lanthanated tungsten electrode provided by two manufacturers were tested through welding on the site with respectively 70 amperes, 150 amperes and 300 volt DC electricity. The test result showed that the 1.5% lanthanated tungsten electrode performed outstandingly under both situations and its low rate of buring also caught eyes.
The lanthanated tungsten electrode is also suitable for AC welding.

Lanthanum Tungsten Electrode is well known its good welding performance. It is the electrode added with 1-2% of LaO, The power of its electronic transgression is 2.7-2.8ev. Bearing the closest features to those of thorium-Tungsten Electrode. Its arc features and burn spoilage endurance are better when used in small or medium currents condition.
Lanthanum-Tungsten Electrode is the most promising substitution product of thorium-tungsten electrode because of its nonradiation. Its another advantage is the endurance of high current but low burn spoilage rate.
