What is Tungsten Electrode ?

 

 

Tungsten welding electrode can be applied for inert gas shield arc welding, plasma arc welding, cutting, painting etc.. It has the performance of high melting point, high density, corrosion resistance, strong ability of electronic emission, conduct electricity, etc. 

 

          

 

Adding some rare earth oxides(CeO2、La2O3 、ThO2), tungsten electrode can be improve in the area of recrystallization temperature increasing and the ability of electronic emission, for that reason, its welding performance may be better than before.Besides argon arc welding,tungsten electrodes are wildly used in xenon lamp, painting fields

 

 

How many kind of Tungsten Electrode?

 

 

 

 

Thoriated-Tungsten Electrode

Radioactive. Compared with pure tungsten electrodes and others, its welding perfomance is more excellent, with the advantages of easy operating, stable electric arc, long-life, ect.

 

 

 

 

 

 

 

 

Lanthanated-Tungsten Electrode

 

Lanthanted tungsten electrode, which is similar to thoriated tungsten electrode with the characters of non-radioactive,excellent electric conductivity and welding performance, high carrying capability, minimum ratio of burnt area, can be substituted for thoriated tungsten electrode, mainly used for DC welding.

 

 

 

 

 

 

 

 

Ceriated-Tungsten Electrode

 

Ceriated tungsten electrode, with easier arc ignition and low arc maintaining current under low current circumstances, is substited for thoriated tungsten electrode, especially for DC welding.

 

 

 

 

 

 

 

 

Zirconium-Tungsten Electrode 

 

Zirconiated tungsten, with the advantages of AC welding, especially under high load current, can not be replaced by any other tungsten electrodes.This kind of tungsten electrode retains a balled end when welding, with corrosion resistance.

 

 

 

 

 

 

 

 

Yttrium-Tungsten Electrode

 

Long and thin arc beam with high compression, deeper burning groove under medium and high current circumstances.

 

 

 

 

 

 

 

 

Pure-Tungsten Electrode

 

Non-addition,requiring a high coltage for arc derivation, low crrent capacity, and easily burnt.

 

 

 

 

 

 

 

 

Black Tungsten Electrode Rod

 

Tungsten electrode rod is manufactured by the processes of forging, drawing, coarse grinding, fine grinding. We can supply customers with any other specification of tungsten electrode rod.

 

 

 

 

 

 

 

 

 

Tungsten rod for thermal sraying

 

The thermal spraying is a method of coating to the surface of components, with the use of gas, liquid or arc, plasma arc as heating sources.The thermal spraying is mainly applied for repairing and protecting of parts. Tungsten bar, with the better usage, is prior to other tungsten materials.

 

 

 

 

 

 

 

The rare earth tungsten bar

 

Unlike the traditional tungsten powder, Blesswmo rare earth tungsten powder due to the addition of suitable amount of rare earth elements, made of tungsten and its downstream products, compared to traditional tungsten powder product, has a stronger electron 

emission ability, are widely used in the manufacture of welding materials, special light source, special powder metallurgy tungsten products.
