Improved varieties of lanthanum tungsten electrode is expected to replace the thorium tungsten products

Lanthanum tungsten electrode is improved varieties of Europe in the eighty's the introduction of hope instead of thoriated tungsten products, once launched, with its excellent welding performance in the international welding industry attention and very popular. Lanthanum tungsten electrode is the most common containing two percent lanthanum oxide (La203), known as the lanthanum oxide. In Europe and Japan, lanthanum tungsten electrode in the majority of applications have been the most commonly used to replace the thorium tungsten electrode. Its excellent conductive performance, the most close to the WT20 thoriated tungsten electrodes. Therefore, don't need to change any welder welding operation procedures can be convenient for the electrodes to replace the thorium tungsten electrode. This kind of change, whether in under the condition of AC or DC conditions are easily. Another advantage is the endurance of high current and low burning rate minimum.
