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 .

Binary alloy of silver and tungsten , whether in liquid or in solid, silver and tungsten are immiscible . There AgW30, AgW60, AgW80 and AgW90 so on. Hardness high arc erosion resistance , anti- adhesion and anti- fusion welding ability. Manufactured by powder metallurgy . More than 60% tungsten alloy production of multi-use impregnated . Used for low-voltage power switch, crane switch, locomotive switch , high current switching pre- contact, as well as heavy-duty relays, air circuit breakers. Cobalt can be added to improve the wettability of silver tungsten , reduce the contact resistance .

Silver and tungsten sintered products , higher conductivity than copper tungsten , as mainly suitable for resistance welding electrodes require high antioxidant work environment . As EDM electrodes of the ordinary copper electrode when the finish is difficult to achieve , so that the abrasive to achieve a very high precision.

AGW-70 silver tungsten electrode materials, and mainly used in welding materials ; such as : low-voltage automatic switch, high voltage circuit breakers and protection switch and so on.

Need for silver tungsten electrodes , usually difficult to machine tool processing equipment and high- quality finish electrode, the electrode repair ordinary copper electrode to achieve the best finish , making the mold to achieve very high accuracy.

People never stopped research on tungsten electrodes , thoriated tungsten electrodes from the basic to the present cerium tungsten electrode , lanthanum tungsten electrode , and the composite rare earth tungsten electrodes , gradual process and product quality innovation and progress forward . The composite rare earth tungsten electrode is the latest scientific research , our scientists are only carried out vigorously develop . One called ternary complex of tungsten electrode product was born.

Ternary rare earth tungsten electrode is a newly developed green electrode products, with excellent overall welding performance. This is the most promising substitute radioactive contamination of thorium tungsten motors, but because rare earth compound added three constituents , so the production process to bring a new problem , the tungsten electrode swaged and brushed finished products during processing rate decreased significantly. The researchers based swaging process temperature and pass deformation in different designs of the two processes. Plasticity of the electrode integrated use of the various stages of the process of optical metallographic microscopy , scanning electron microscopy and X- ray diffraction analysis and other methods of processing materials were obtained electrode microstructure analysis, we found the two in the formation process fibrous tissue with different characteristics . Good processing performance in which processing technology , fibrotic tissue fibers of uniform width , between the fibers arranged in neat rows . The researchers found that the type of processing parameters of the various stars fibrous tissue , and thus have different yield. Swaging process by adjusting the process parameters to improve the ternary complex of rare earth tungsten electrode production yield.

Ternary complex of rare earth production and application of tungsten electrodes , longevity good economic and social benefits.
