In the pure tungsten electrode, the electrode head is generally spherical and is generally used in the AC process of the sine wave and the traditional square-wave argon arc welder. After forming a sphere, in order to know that the diameter of the electrodes is generally simple to use in alternating current, and eventually will have their own form. The spherical diameter should not exceed 1.5 times times the electrode diameter (for example, the spherical diameter is 1/8, then the electrode diameter is 3/16), at the tip of a larger spherical body of the electrode can reduce the arc stability and even fall off, and weld will be contaminated.Pure Tungsten Electrode
A pointed or truncated head used in a pure tungsten electrode, cerium, lanthanum, and thorium electrodes is applied to the AC and DC welding process of the inverter. To properly grind the tungsten in order to avoid abrasive contamination to be used specially made grinding wheel, it is made of boron nitride or diamond can withstand the hardness of tungsten. Therefore, it is suitable for pure tungsten electrodes.
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
The total consumption of tungsten electrodes worldwide is up to 1600t per year, and market demand continues to grow with the development of the economy. The annual output of China tungsten electrode accounts for about 3/4 of the world's tungsten electrode production. The annual output of China's tungsten electrodes has been growing steadily, and production has grown significantly since 2005, reaching 1200t in 2009.Pure Tungsten Electrode
