The Zirconium Tungsten Electrode And Tungsten Electrodes Innovation

Tungsten electrodes are now an essential welding process of welding . The earliest tungsten electrodes are tungsten and tungsten -based synthetic metals thorium tungsten alloy . After a period of use , it was found downstream element thorium radioactive, radiation injury on the human body . So from what people have to study the new tungsten electrodes to replace the use of tungsten electrodes . Soon a number of tungsten electrodes was born. < br />
In the 1980s , the emergence of yttrium tungsten electrode , because too many flaws of this electrode was gradually abandon the use of people .

Continued innovation in the 1990s , Beijing was born lanthanum tungsten electrode , the current from the performance indicators in terms of lanthanum tungsten electrode is the best alternative thorium tungsten electrode products , is now generally recognized.

In addition to the familiar cerium tungsten electrodes there is an intermediate product called zirconium tungsten electrode . Tungsten containing zirconia . Motor performance in the pure tungsten and thorium tungsten electrode. Tungsten in order to avoid the motor itself easily under high load conditions and the development of the melting conditions . Zirconium tungsten electrodes in AC current conditions showed good welding electrode tip can maintain spherical, and the arc is much more stable than pure tungsten electrodes . Zirconium tungsten electrodes biggest feature is that in the case of high load current welding, this electrode structure to reduce spherical tungsten seepage phenomenon and has good corrosion resistance. In general this zirconium tungsten electrodes for aluminum and its alloys will America AC welding .

The use of tungsten electrodes will determine the construction of the entire country , and even said that the earth of the welding industry. Five o'clock in the future will develop into what size , wait and see. Energy-saving , high efficiency which is getting good .
