good welding performance 1.6mm 2.4mm 3.0mm tungsten electrode

Tungsten welding electrodes can be applied for inert gas shield arc welding, plasma arc welding, cutting, painting, etc. Tungsten electrode has the performance of high melting point, high density, corrosion resistance, strong ability of electronic emission, conduct electricity, etc. Adding some rare earth oxides(CEO, La O, ThO ), tungsten electrode can be improved in the area of recrystallization temperature increasing and the ability of electronic emission, for that reason, its welding performance may be better than before. During the past years, thoriated tungsten electrodes were wildly used in the field of inert gas shield arc welding, plasma arc welding, cutting. However, radioactive and unhealthy, compared with other tungsten electrodes, thoriated tungsten electrode will be replaced by created tungsten, lanthanide tungsten, Multicompond, Rare-earth tungsten electrode, etc. Besides argon arc welding, HL tungsten electrodes are wildly used in xenon lamps, painting fields.
