Argon belongs to the family of inert and rare gases of the atmosphere. It is plentiful compared to the other rare atmospheric gases; 1 million ft3 (28 300 m3) of dry air contains 9340 ft3 (264 m3) of argon. Argon is colorless, odorless, tasteless and nontoxic. It is extremely inert and forms no known chemical compounds. It is slightly soluble in water. Argon is manufactured in air separation plants by means of fractional distillation after the liquefaction of air.

APPLICATION OF ARGON GAS IN INDUSTRY

  • All of the major applications of Argon are related to the production, processing and fabrication of metals. The role of Argon is nearly always to exclude atmospheric air from contact with metal alloys. An example of this is as a purging gas to protect weld areas, such as the inside of pipes during welding.
  • The predominant gas used in shielding gases because it forms a very good shield due to the high density and total inertness.
  • Used on a wide range of ferrous and non-ferrous materials for welding and cutting.
  • Shielding gas for MIG and TIG welding processes and for plasma-cutting. Argon is used alone or mixed with other gases such as Helium, Carbon Dioxide, Oxygen, Nitrogen or Hydrogen. Each mixture is often specific to welding a particular material or to a particular process. For example, Argon is used as a shielding gas for TIG-welding aluminium, titanium and copper.
  • When MIG-welding ferrous materials, pure Argon is not an ideal shielding gas, as it produces an arc with poor cathodic rooting characteristics, large droplet size and therefore higher levels of spatter. For this reason, BOC recommends that Argoshield or Stainshield gases be used depending on the thickness and type of material being welded.
  • Fills the inter-space in double-glazed windows.
