WY20 Yttrium Tungsten Electrode

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 .
