- The electrode materialTungsten
When welding by a tungsten electrode in the environment of inert gases for achievement of the best result except a welding torch and the power supply an important role is played by the heat-resistant not melting electrode.
Electrodes from a tungsten alloy with oxide of lanthanum have very easy initial start of an arch, low tendency to prozhoga, a steady arch and the excellent characteristic of repeated ignition of an arch.
Addition of 2,0% of oxide of lanthanum increases the maximum current, the bearing ability of an electrode is about 50% more for this standard size when welding on alternating current, than purely tungsten. In comparison with ceric and thorium, lantanirovanny electrodes have smaller wear of the working end of an electrode.
Lantanirovanny electrodes are more durable and pollute tungsten a welded seam less. Oxide of lanthanum is evenly distributed on electrode length that allows to keep a long time when welding initial sharpening of an electrode. Lantanirovanny electrodes are used when performing welding works on constant (DC) and variable (AC) currents and only in protective environments (for example in argon) excluding oxygen availability.
The steady arch when welding by these electrodes will be even on very low welding currents, and to receive burned thin metal it is almost impossible.
