High Levels of Tungsten Electrode Invention Yttrium

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 .
