Yttrium tungsten electrode contains 1.8%-2.2% yttria, its electron work function is 2. 8eV-3.2eV. When used in welding, yttriated Tungsten is primarily used in military and aviation industry with narrow arc beam, high compressing strength, highest welding penetration at medium and high current. Its superior performance also recommends use in the welding of high strength titanium bearing components, as well as high-temperature jet engine components using a single crystal or coarse-grained materials, intermetallic compounds, ceramic or metal matrix composites and other new materials. Therefore they are mainly applied to military industry and the aerospace industry.
