The Lanthanated tungsten electrode is European countries introduced in the eighty s hope replace thorium tungsten products improved varieties, once launched, with its excellent welding performance attention and is very popular in international welding area. Its characteristic is the most nearly 2% thorium-tungsten electrode conductivity, endurance of high current and low burn spoilage rate.
The most common lanthanum tungsten electrode contains 2 percent lanthanum (La203), known as lanthanum oxide.Lanthanum tungsten electrode is the most commonly used to replace thorium tungsten electrode in most applications.There are 2% lanthanum oxide, 1.5% of lanthanum oxide and 1% of lanthanum oxide.
Lanthanum oxide has the lowest electron escape work, the easiest of the arc, the lowest point temperature, which can help prevent grain growth and improve service life.
Life expectancy is longer than thorium tungsten electrode
