Shielding gas, the Glossary

Shielding gases are inert or semi-inert gases that are commonly used in several welding processes, most notably gas metal arc welding and gas tungsten arc welding (GMAW and GTAW, more popularly known as MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas), respectively).^[1]

Deoxidization

Deoxidization is a method used in metallurgy to remove the oxygen content during steel manufacturing.

See Shielding gas and Deoxidization

Dichlorodifluoromethane

Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant.

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).

See Shielding gas and Electrode

Ferrous

In chemistry, iron(II) refers to the element iron in its +2 oxidation state.

See Shielding gas and Ferrous

In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent.

See Shielding gas and Flux (metallurgy)

Flux-cored arc welding

Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. Shielding gas and Flux-cored arc welding are arc welding.

See Shielding gas and Flux-cored arc welding

Forming gas

Forming gas is a mixture of hydrogen (mole fraction varies) and nitrogen. Shielding gas and Forming gas are Industrial gases and welding.

See Shielding gas and Forming gas

Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join). Shielding gas and gas metal arc welding are arc welding and Industrial gases.

See Shielding gas and Gas metal arc welding

Gas tungsten arc welding

Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. Shielding gas and gas tungsten arc welding are arc welding.

See Shielding gas and Gas tungsten arc welding

Helium

Helium (from lit) is a chemical element; it has symbol He and atomic number 2.

See Shielding gas and Helium

Hobby

A hobby is considered to be a regular activity that is done for enjoyment, typically during one's leisure time.

See Shielding gas and Hobby

Hour

An hour (symbol: h; also abbreviated hr) is a unit of time historically reckoned as of a day and defined contemporarily as exactly 3,600 seconds (SI).

See Shielding gas and Hour

Hydrogen

Hydrogen is a chemical element; it has symbol H and atomic number 1.

See Shielding gas and Hydrogen

Hydrogen embrittlement

Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen.

See Shielding gas and Hydrogen embrittlement

Hypoxia (medicine)

Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level.

See Shielding gas and Hypoxia (medicine)

Inert gas

An inert gas is a gas that does not readily undergo chemical reactions with other chemical substances and therefore does not readily form chemical compounds. Shielding gas and inert gas are Industrial gases.

See Shielding gas and Inert gas

Laser beam welding

Laser beam welding (LBW) is a welding technique used to join pieces of metal or thermoplastics through the use of a laser. Shielding gas and laser beam welding are welding.

Litre

The litre (British English spelling) or liter (American English spelling) (SI symbols L and l, other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metres (m3). A cubic decimetre (or litre) occupies a volume of (see figure) and is thus equal to one-thousandth of a cubic metre.

See Shielding gas and Litre

Mill scale

Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (wüstite), iron(III) oxide (hematite), and iron(II,III) oxide (magnetite).
