What is the melting point of tungsten?

The melting point of tungsten is approximately 6200 F. This information is crucial in the context of Gas Tungsten Arc Welding (GTAW) because tungsten is used as the electrode material, and its ability to withstand high temperatures without melting is essential for effective welding.

Tungsten has the highest melting point of all metals, which allows it to maintain its integrity and not oxidize quickly in the presence of the electric arc during the welding process. This high melting point ensures that the tungsten electrode can be re-used for extended periods without significant wear or degradation.

Understanding the properties of the tungsten electrode, including its melting point, helps welders select the appropriate type of tungsten for various applications in GTAW, ensuring better results in terms of arc stability and weld quality.
