The Shape And Use Of 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 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 electrodes have excellent properties: steam pressure, low resistance, good conductivity, small thermal expansion, high modulus of elasticity.Pure Tungsten Electrode
   Application: The use of pure tungsten electrodes is most widely used under alternating welding alternating current. It is generally used for welding aluminum, magnesium alloy (AC) is generally used under AC. The pure tungsten electrode can also be provided with a clean, heated solder ball sharpened. This shape provides a balanced waveform AC welding arc stability and is particularly good. The pure tungsten electrode also provides a good arc stability of the sine wave alternating current welding of aluminum, magnesium. However, they are not used for DC soldering. Pure tungsten electrodes are widely used in specific welding applications in various industries.Pure Tungsten Electrode
