  4. Argon - Wikipedia

    en.wikipedia.org/wiki/Argon

    Compressed argon gas is allowed to expand, to cool the seeker heads of some versions of the AIM-9 Sidewinder missile and other missiles that use cooled thermal seeker heads. The gas is stored at high pressure. [49] Argon-39, with a half-life of 269 years, has been used for a number of applications, primarily ice core and ground water dating.

    en.wikipedia.org/wiki/Safety_data_sheet

    An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.

  6. Shielding gas - Wikipedia

    en.wikipedia.org/wiki/Shielding_gas

    A-25 (25% argon/75% helium) is used for nonferrous base when higher heat input and good weld appearance are needed. A-50 (50% argon/50% helium) is used for nonferrous metals thinner than 0.75 inch for high-speed mechanized welding. A-75 (75% argon/25% helium) is used for mechanized welding of thick aluminium. Reduces weld porosity in copper. [14]

  8. Inert gas - Wikipedia

    en.wikipedia.org/wiki/Inert_gas

    The more carbon dioxide that is added to the inert gas, such as argon, will increase penetration. The amount of carbon dioxide is often determined by what kind of transfer is used in GMAW. The most common is spray arc transfer, and the most commonly used gas mixture for spray arc transfer is 90% argon and 10% carbon dioxide.
