Tungsten electrode is introduced: pure tungsten electrode is the earliest electrode used in argon arc welding, but under the condition of DC welding, the electrode of the product is easy to be unstable, and adding rare earth oxides can greatly improve the situation. Therefore, the product is used only as a welding electrode under AC condition or as a resistance welding electrode.Pure Tungsten Electrode
Pure Tungsten Electrodes are the earliest electrodes used in argon arc welding, however, under the condition of DC welding, the electrode of the variety can not be arcing or maintain instability, and adding rare earth oxides could greatly improve the situation, therefore, the pure tungsten electrode is only used as the welding electrode under AC condition or as the resistance welding electrode.Pure Tungsten Electrode
The pure tungsten electrode contains the lowest 99.5% tungsten, no alloying element. Pure Tungsten has a very high electron escaping power, so it is more difficult to arc the pure tungsten electrode than other alloy tungsten electrodes, and it is more difficult to maintain the stability of the arc beam. In addition, because of the high electron escaping power, the electrode tip temperature is higher and the grain is easy to grow, which will lead to the instability of the arc beam, the arc is more difficult, and the service life is shorter. Pure tungsten is used only for AC welding, but good DC can also be selected.Pure Tungsten Electrode
