WL20镧钨电极

WL20镧钨电极
镧钨电极  WLa (Lanthanum-Tungsten Electrode)
 
   镧钨电极焊接性能优良，本产品在钨中添加1—2% La2O3的电极，电子逸出功在2.7-2.8ev,

具有与钍钨电极最相近的性能。在中小电流使用时电弧性能和耐烧损性能比钍钨电极都有提高。
   镧钨电极因无放射性而成为较有发展前景的钍钨电极的替代产品。它的另一优点是耐用电

流高而烧损率最小，因此镧钨电极深受亚洲、欧洲、美洲和日本等国家客商的青睐。
 
Lanthanum -Tungsten Electrode is well known for its good welding performance .It

is the electrode added with 1-2% of La2O3.The power of its electronic transgression

 is  2.7-2.8ev ,bearing the closest features to those of the  Thorium - Tungsten

Electrode. Its arc features and burn spoilage endurance used with small and medium

currents.
   Lanthanum-Tungsten Electrode is the substitution product of thorium-tungsten

 electrode because of its non-radiation. Its other advantage is its endurance

of high current and low burn spoilage rate.
