Processing Method of Tungsten Yttrium Electrodes
The manufacturing tungsten yttrium electrodes methods are different in manufacturers. Here, there is a method to make tungsten yttrium electrodes, which can have a better welding performance. Following is three procedures to make tungsten yttrium electrodes.
First of all, mix yttrium nitrate aqueous solution with a solid of APT or WO3 well-distributedly by the methods of spaying and coating. Then heat it to the state of tungsten yttrium coated powder.
Secondly, reduce tungsten yttrium coated powder in twice to tungsten yttrium powder. After reduction, make tungsten yttrium powder into tungsten yttrium billet by pressing and sintering.
Finally, press and forge tungsten yttrium billets into tungsten yttrium electrodes.

Yttrium tungsten electrodes are mainly applied in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current.
Composite tungsten electrodes are electrodes adding two or two more rare earth oxides into tungsten, which are complementary to better their welding performance. Thus, they become extraordinary in electrodes family.
Cerium tungsten electrodes are tungsten electrodes with 2% CeO2, which are non-radioactive materials. They are widely used in low amperage and require only about 10% less amps to operate than thorium tungsten electrodes.
