Technical characteristics
Tungsten electrodes with the addition of yttrium are mainly used in military and aviation industry. They are distinguished by higher strength values in compression, and the highest level of penetration of the heat from the welding arc to the inside of the welded materials. Effective when using medium and high welding currents. During welding tungsten yttrium electrodes to create a subtle arc with the maximum concentration volumetric heat capacity.

Application
The data type of electrodes used primarily in electric arc welding using a constant current. tungsten electrodes containing yttrium, cook critical metal structures of complex shapes of all kinds of steel (including stainless), and such non-ferrous metals and alloys like brass and titanium. Yttrium-tungsten electrodes among similar non-consumable electrodes have the highest possible durability. The range of electrodes: diameter from 1.0 up to 10.0 mm, in length from 75 to 300 mm (electrodes with a diameter of 1 mm is allowed to produce in rolls in length up to 3000 m).
