2. Gas metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_metal_arc_welding

   Spray transfer GMAW. 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).

3. Shielding gas - Wikipedia

   en.wikipedia.org/wiki/Shielding_gas

   These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or active shield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals. Most of these gases, in large quantities, would ...

5. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   Gas metal arc welding Man welding a metal structure in a newly constructed house in Bengaluru, India. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a binding of the metals.

6. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   Gas metal arc welding (GMAW), also known as metal inert gas or MIG welding, is a semi-automatic or automatic process that uses a continuous wire feed as an electrode and an inert or semi-inert gas mixture to protect the weld from contamination. Since the electrode is continuous, welding speeds are greater for GMAW than for SMAW.

7. Slag (welding) - Wikipedia

   en.wikipedia.org/wiki/Slag_(welding)

   Shielded metal arc welding process, showing slag Welding flux is a combination of carbonate and silicate materials used in welding processes to shield the weld from atmospheric gases. When the heat of the weld zone reaches the flux, the flux melts and outgasses.
