Lanthanum - tungsten electrode is currently the most popular international electrode materials, especially the content of 1.5% ( with a content of 2% difference ) of lanthanum tungsten electrode. Scientific studies show that, 1.5% lanthanum tungsten has the closest 2% thorium tungsten demonstrated by the conductive performance, therefore, the welding personnel can easily replace the electrode, without changing the parameters of the equipment. In ***8 there was a very famous field test, is the 2% thoriated tungsten electrodes, tungsten electrodes 2% and two manufacturers of 1.5% tungsten electrodes respectively in *0 and **0 amperes of electric current, **0 V DC welding task environment, the fruit is, in these two cases, 1.5% lanthanum tungsten electrodes show the excellent welding performance, at the same time, but also reflects its burn rate of small features. Lanthanum - tungsten electrode is also applied to the AC welding task, and performance.
