Product Description

Tungsten electrode
Pure tungsten electrode is the earliest electrode used for argon arc welding. However, under the condition of dc welding, this kind of electrode is prone to arc failure or unstable maintenance, which can be greatly improved by adding rare earth oxides. Therefore, pure tungsten electrode is only used as a welding electrode under ac condition or as a resistance welding electrode. Pure tungsten electrode contains a minimum of 99.5% tungsten, no alloying elements. Pure tungsten has a very high electron ejection work, so it is more difficult for pure tungsten electrode to start arc and maintain the stability of arc beam than other alloy tungsten electrodes. In addition, due to the high electron escape work, the electrode tip temperature is higher and the grain growth is easy to occur, which will lead to the arc beam instability, arc initiation is more difficult, and the service life is shorter. Pure tungsten is only used for ac weldingMaterials
Pure tungsten electrodes are generally used for welding aluminum and magnesium alloys under alternating current.
tungsten electrodes: - Pure tungsten - Tungsten + cerium - Tungsten + lanthanum - Tungsten + rare earths
All these tungsten eletrodes are in conformity with ISO 6848 / EN 26848 standards.
