Tungsten Hexafluoride Gas – WF6. Tungsten hexafluoride (WF 6) has one of the highest densities of any gas. To produce tungsten hexafluoride gas, pure tungsten metal powder (W) reacts with fluorine gas (F 2) between 650F (343C) and 750F (399C). These elements combine to create a gas that has a density of 12.9 g/l.

In this process, a non-consumable tungsten electrode is used to generate heat for fusing the base metal & filler wire. An externally supplied filler wire is added manually to the welding arc. As the name suggests, shielding gas such as Argon and Helium or a mixture of these inert gases are used for gas shielding purposes.
