Zirconia doped tungsten, zirconium tungsten electrodes produce. Specific data as follows:

Other grades dopant doping doping electron work function color coating head

WZ3 ZrO2 0.20 ~ 0.40% <0.20% 2.5 ~ 3.0 Brown
WZ8 ZrO2 0.70 ~ 0.90% <0.20% 2.5 ~ 3.0 White

Zirconium tungsten electrodes and pure tungsten electrodes, can only be of the AC welding work environment.

Zirconium tungsten electrodes in AC environment, good weldability. Especially in the case of high load currents, zirconium tungsten electrodes shown superior performance of the other electrode can not be replaced.

In welding, the end portion of the tungsten electrode of zirconium to maintain a reduced spherical tungsten infiltration phenomenon, and has good corrosion resistance.

Since the emergence of other alternative products, zirconium tungsten electrode demand will have a decreasing trend. Main alternative product is lanthanum tungsten electrode.

Zirconium Tungsten Electrode Characteristics

In welding, the end portion of the tungsten electrode of zirconium to maintain a reduced spherical tungsten infiltration phenomenon , and has good corrosion resistance . Since the emergence of other alternative products , zirconium tungsten electrode demand will have a decreasing trend . Main alternative product is lanthanum tungsten electrode .

The Use of Zirconium Tungsten Electrode

Zirconium tungsten electrodes , but also for radiation quality welding . Requires minimal best application tungsten contamination . Zirconium tungsten electrodes are generally applied alternating current, not recommended for direct current. Tungsten electrodes made ​​of zirconium and its alloys for Mg AC welding . zirconium tungsten electrode welding special to pure tungsten electrodes located and thorium tungsten electrode, is to improve the pure tungsten electrode welding conditions at high load melt easily under their own further pollution and the development of the drawbacks of the workpiece tungsten electrodes product. 10 pcs / plastic box , the length is 150mm or 175mm, 1000只per carton .

Now there are many types of tungsten electrodes , the new generation and application of bulldozing will gradually phase out old products. Tungsten also has been the development of innovation . Especially in relatively hot composite rare earth tungsten electrodes . But I have used a total of tungsten electrodes also has good quality , with so not being taken seriously , but in the history of the tungsten electrode Send a connecting link between the river played a role .

Introduced in front of lanthanum tungsten electrodes , thoriated tungsten electrodes , said today that the zirconium tungsten electrode . Zirconium tungsten electrodes in order to improve the motor innocent large tungsten at high load conditions, contamination of the workpiece is easy to melt their drawbacks of an electrode for the development of varieties , the biggest feature is the high load currents , the end of this motor a spherical portion can be maintained to reduce the phenomenon of infiltration of tungsten , with good corrosion resistance.

Zirconium tungsten electrodes are based on the zirconia containing a small amount . Once thoriated tungsten electrode and the common electrode zirconium tungsten electrodes are , generally speaking in nature , zirconium tungsten electrodes is the best non-radioactive tungsten electrodes . Zirconium tungsten electrodes in the case of the use of alternating current with good performance.

Lanthanum tungsten electrode application and now composite rare earth tungsten electrodes gradually occupied the tungsten electrodes market. The use of zirconium tungsten electrode less .

Zirconium tungsten electrode is the main component

Zirconium tungsten electrodes with a small amount of zirconia . Zirconium tungsten electrode welding characteristics , in general, in pure tungsten electrodes and thoriated tungsten electrodes. In AC welding , zirconium tungsten electrode is the most common , because welding easier than pure tungsten arc , and the arc beam stability, but also can be a good prevention of pollution , carrying capacity is also good, from a performance point of view, overall zirconium tungsten electrode is the best non-radioactive tungsten electrodes .

The main ingredient is the element content in the total composition 98 to 98.8 % tungsten , 0.91 to 1.2% zirconium , 0.01 to 0.07% of yttria of 0.01 to 0.02% of cobalt .
