WY20 Yttrium tungsten electrodes for TIG welding blue , which is a tungsten matrix by powder metallurgy method of incorporation of about 0.3% -5% of a rare earth element , such as : cerium, thorium , lanthanum , zirconium, yttrium and the production of tungsten alloy strip , and then after pressure processing, diameters from 0.1 to 80mm, standard length from 75 to 600 , while the most commonly used specifications for diameter 1.0,1.6,2.4 and 3.2 , electricity extreme in terms of the shape of the TIG is a important factor when using DCSP , the power ground terminal to be pointed shape , and the angle of the tip with the application, electrode diameter , and welding current to change , narrow tip joint requires a smaller angle , when the welding very thin material, to be low current , like the needle electrodes for a minimum to stabilize the arc , and to ensure proper grounding electrode arc easily , good arc stability and appropriate weld bead width . When the AC power to the welding, grinding electricity without the extreme , because using the appropriate welding current, electrode terminals will form half of the ball , if the increase in the welding current, electrode tip becomes bulb -shaped and may melt and contaminate molten gold .

Yttrium tungsten electrode ( grades WY20) in the welding arc beam slim , compress large degree , in the medium and high current penetration is relatively large , mainly used in military industry and the aerospace industry .

Yttrium is a chemical element , its chemical symbol is Y, its atomic number is 39 , is a silvery-white transition metal . Yttrium is a silver with metallic gloss rare earth metals , it is fairly stable in the air , it is chemically similar characteristics and lanthanum . Yttrium debris in air at 400 degrees Celsius can be spontaneous , its powder is unstable in the air . In the process of nuclear absorption of its middle section is small. Average price of yttrium oxide +3 .

Yttrium rare earth metals are common . Wherein the two compounds of yttrium YVO4: Eu and Y2O3: Eu can be used to produce a red color television phosphors .

Yttrium tungsten electrode tungsten, yttrium products. Blue distinction as its symbol . High compressive strength, high and medium current welding high permeability .

Yttrium tungsten electrode welding, arc beam slender, compression large, medium and high current when its maximum penetration . Mainly used in military industry and aerospace industries .

Yttrium tungsten electrode packaging requirements : 10 / plastic box , the length is 150mm or 175mm, 1000 per carton .

High levels of yttrium tungsten electrode welding, electron emission ability, slender arc beam , a large degree of compression , in the middle of its large current penetration is relatively large. High levels of tungsten, yttrium electrode yttrium content of 1.8-2.2 %, and the electron escape Gong Wei 2.0-3.9 % .

High levels of yttrium tungsten electrode tungsten yttrium invention discloses a high quality method of manufacturing an electrode , the method comprising :

a. Would doped yttrium nitrate aqueous solution spray evenly mixed with solid material way paratungstate (APT) or tungsten trioxide , heated drying coating made ​​of tungsten, yttrium powder ;

b. Obtained for the yttrium -coated tungsten powder obtained after reduction twice yttrium tungsten powder , after pressing, sintering made ​​of tungsten, yttrium billet ;

c. Forging pressure processing manner using the obtained tungsten billet made ​​of yttrium Yttrium tungsten electrode . In this method, the yttrium nitrate aqueous solution was sprayed Doping mixed with ammonium paratungstate (APT) or tungsten oxide in the solid material in spray form the yttrium nitrate aqueous solution encapsulated in the ammonium paratungstate (APT) or tungsten trioxide of the surface to mixing, stirring, with the completion of drying , to prepare a uniform coated yttrium tungsten powder , improve the production capacity and make more uniform powder coating , yttrium tungsten effectively improved the performance in the welding electrodes .

Zirconium Tungsten Tungsten electrodes for TIG welding , which is a tungsten matrix by powder metallurgy method of incorporation of about 0.3% -5% of a rare earth element such as : cerium, thorium , lanthanum , zirconium, yttrium and the production of tungsten alloy strip , then after pressure processing, diameters from 0.1 to 80mm, standard length from 75 to 600 , while the most commonly used specifications for diameter 1.0,1.6,2.4 and 3.2 , the shape of the TIG electrode terminal is an important factor in terms of , when using DCSP , the power ground terminal to be pointed shape , and the angle of the tip with the application, electrode diameter , and welding current to change , narrow edge connectors require a smaller angle , when the weld very thin material, required low current , like needle electrodes for a minimum to stabilize the arc , and to ensure proper grounding electrode arc easily , good arc stability and appropriate weld bead width . When the AC power to the welding, grinding electricity without the extreme , because using the appropriate welding current, electrode terminals will form half of the ball , if the increase in the welding current, electrode tip becomes bulb -shaped and may melt and contaminate molten gold .

Zirconium tungsten electrode ( grades WZ3, WZ8) under the conditions of the AC welding performance is good, and has good corrosion resistance. Especially in the case of high load currents , zirconium tungsten electrodes increased performance can not be replaced by other electrodes . In welding , the end portion of the tungsten electrode of zirconium to maintain a reduced spherical tungsten infiltration phenomena , conditions suitable for the exchange of Mg alloys.
