Lanthanum Tungsten Electrode Conductivity

Lanthanum tungsten electrodes is already the internationally popular electrode materials, especially the content is 1.5% ( with a content of 2.0% difference) lanthanum tungsten electrode . Scientific research study showed that 1.5% lanthanum tungsten, tungsten thorium with the nearest 2.0% demonstrated conductive properties, therefore , welding personnel can easily replace the electrode , rather than replace the device parameters. In 1998 there is a very famous field trials , is to 2.0% thoriated tungsten electrodes , 2.0% cerium tungsten electrodes and two vendors 1.5% lanthanum tungsten electrodes at 70 Ann 150 amps , 300 volts DC environment for welding tasks , the fruit is , in both cases , 1.5% lanthanum tungsten electrodes have demonstrated its excellent welding performance , but also reflects its small burn rate characteristics. Lanthanum tungsten electrode is also suitable for AC welding tasks , and performance excellence.

Lanthanum tungsten electrode welding because of its good performance in the international welding industry concern. Lanthanum tungsten electrode conductivity closest WT20 thorium tungsten electrode . Therefore , welders welding operation without changing any program can use this convenient alternative thorium tungsten electrode electrode . This shift , whether in exchange conditions or under DC conditions are easier. Another advantage of lanthanum tungsten electrode performance at its current high durability and burning the minimum rate .
