Argon – Argon Gas – Argon Gas Suppliers

Argon is the third noble gas, making up about 1% of our atmosphere. Argon is 2.5 times more soluble in water than nitrogen and is about as soluble as oxygen. Argon is gaseous at STP and is a chemically inert element gas that is colourless and odourless.

Argon is the most frequently used inert gas. Argon is the primary TIG welding gas as a shielding gas for most metals. Argon is also used for MIG welding aluminium and MIG brazing. Pure CO2 and argon and CO2 mixtures are the most common active gases used for MIG welding gas, aside from MIG brazing and aluminium.

Argon gas is an inert gas, with the chemical symbol “Ar”. Argon is a non-flammable gas and it is a noble gas that is almost completely non-reactive with all materials at all temperatures and pressures. Argon is heavier than air so it could be a dangerous asphyxiant in an enclosed space.

Argon is typically used when a dry, inert atmosphere is required. It is used in the production of reactive elements, including titanium. It is also used by welders as a shielding gas to protect the weld, in incandescent light bulbs to stop oxidation of the filament and in double-paned windows, for its superior acoustic and thermal properties.

Argon gas is mostly used as TIG or GTAW welding gas, shielding gas and purging gas, supplied in argon gas bottle-cylinder sizes. Argon gas is the principal gas used in shielding gas applications due to its high density and total inertness.

The low ionising potential of argon allows easy forming of a welding arc without reacting with the metal components being welded.

Argon gas can be used on a wide range of ferrous and non-ferrous metals for welding and cutting. Argon is the most affordable alternative when nitrogen is not sufficiently inert.

Argon is also used as an insulating gas between the panes of dual pane windows, as it has low thermal conductivity, pumped in between with argon gas bottle pressure.

Argon is stored and transported in various argon gas bottle-cylinder sizes and larger vessels.

Argon Gas Bottle

Argon gas bottles are steel pressure vessels for holding compressed argon gas. Argon gas bottle gauge pressure is in a range from 15,800 kPa to 30,000 kPa. The outlet connection type is AS 2473 Type 10.

Argon Uses – What is Argon Used For? Common Uses of Argon

Argon uses are varied. Common uses of Argon include shielding gas in welding, the electronics industry, abattoirs, fire retardants, light globes and window insulation.

  • Argon shielding gas bottles for MIG and TIG welding processes and for plasma cutting
  • Argon gas bottles for welding and cutting a wide range of ferrous and non-ferrous materials
  • Argon welding gas bottles are used in arc weldings such as gas metal arc welding and gas tungsten arc welding, as shielding gas.
  • In the electronics industry, argon is used for growing crystals of silicon and germanium in a controlled atmosphere.
  • Argon is used in the poultry industry to asphyxiate birds, as it is more humane than other abattoir options.
  • Argon is used for extinguishing fires in special instances where product or equipment might be damaged by foam, water or other extinguishing agents.
  • Argon is used inside incandescent light bulbs/globes. Argon preserves the filaments from oxidation at high temperatures, by displacing oxygen.
  • Argon is used in dual paned windows for thermal insulation, pumped in between the panes with argon gas bottle pressure, providing more energy-efficient windows.

Argon Welding – MIG Welding with Argon Welding Gas

Argon is the most frequently used inert gas. Argon is the primary TIG welding gas as a shielding gas for most metals. Argon is also used for MIG welding aluminium and MIG brazing. Pure CO2 and argon and CO2 mixtures are the most common active gases used for MIG welding gas, aside from MIG brazing and aluminium.

Argon gas welding is arc welding. The argon gas acts as a shielding gas, shielding the weld which is made by a TIG electric arc jumping between a tungsten electrode and the base metal work surface.

MIG welding with argon welding gas is the most common application for argon gas bottle sizes. MIG argon welding gas mix is frequently referred to as shielding gas for MIG welding and include argon, argon welding gas mixtures, pure CO2 and helium in blended argon gas bottle sizes.

MIG is the acronym for “Metal Inert Gas”. MIG welding means Metal Inert Gas welding with argon welding gas.

MIG welding is an arc welding process that joins metals by melting them with heat.

Argon Facts

The following are some interesting argon facts:

  • The original chemical symbol for argon was “A” but later changed to “Ar”.
  • Argon is number 18 on the periodic table
  • The name “argon” comes from the Greek “Argos”. It means “the lazy one” in reference to its inert nature and chemical inactivity.
  • The atmosphere contains about 0.9 % of argon.

Argon Gas Formula

The argon gas formula or molecular formula is Ar, with the atomic number 18. Argon is a noble gas and is monoatomic.

What Colour is Argon Gas?

TIG Welding with Argon Welding Gas

Argon welding gas is also used in TIG welding. TIG welding gas is typically a mixture of argon with helium, hydrogen and/or nitrogen added for better welding speeds and process stability.

TIG is an acronym for “Tungsten Inert Gas”. TIG welding gas is also used with gas tungsten arc welding (GTAW), using a tungsten electrode and argon shielding gas.

TIG welding gases are inert gases used as shielding gases in the TIG welding process. Argon shielding gas protects the weld pool from nitrogen absorption and oxidation during TIG welding. You get improved weld quality and less rework time.

Who Discovered Argon?

1785 – Argon was hypothesised as a component of air by Henry Cavendish.

1882 – New lines in the colour spectrum indicated a new unknown gas within the air, based on research by H. F. Newall and W. N. Hartley.

1894 – Lord Rayleigh and Sir William Ramsay first isolated Argon from the air. To achieve this, they removed the oxygen, carbon dioxide, water, and nitrogen from clean air and deduced Argon from what remained.

How is Argon Made?

  • Argon is produced using fractional distillation.
  • Argon is cryogenically separated from the air in a distillation tower.
  • The entire installation is known as an Air Separation Unit – ASU.
  • The argon is then stored as a liquid, in argon gas bottles, for ease and economical transportation.
