It is a non-radiation material. It is good to balance the electron mobility and evaporation rates making tungsten electrodes to maximize their performances. For compound tungsten electrode it's easy to start and restart arc. If the welding cycle more than 15 minutes its life will be last longer. WR20 tungsten electrode tip burning significantly better than other tungsten electrodes. As three kinds of doping the oxide mixture in the electrode. It's strict with the production process and the cost of production is more expensive.
