Tungsten rod is an ideal material to make thermal conductors, welding electrodes, headpieces for the industries of quartz, stirring bars for smelting, heavy hammers, fasteners, etc.
Tungsten Inert Gas (TIG) Welding
The extremely high melting point of the tungsten rod makes it very well-suited to be machined into tungsten electrodes for GTAW and plasma welding. GTAW stands for Tungsten Inert Gas Welding, which is also called Heliarc welding. During the welding process, the tungsten electrode gets heated but doesn’t melt. Tungsten electrode is mostly non-consumable, meaning only a negligible amount of tungsten is consumed during each use.
Stirring Bars For Rear-earth Smelting
The stirring bar used for rare earth metal production by molten salt electrolysis needs to be highly resistant to high temperatures and chemical erosion. Tungsten rod is an excellent material for making the stirring bar due to its high melting point and very stable chemical properties in a working temperature below 1400 °C. Compared with graphite, tungsten rod has a lower consumable rate and higher erosion resistance to the electrolyte.
Tungsten contact is a popular component cut from forged tungsten rod. It is widely used in high voltage and frequency switching operations such as circuit breakers, high voltage switches, and arcing contacts. Tungsten contact has a low surface evaporation rate, excellent arc resistance, and efficient electrical and thermal conductivity. The typical size of tungsten contacts are 2- 6 mm in diameter with a maximum of 0.6 mm in thickness.
