    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).

    Joining rails in situ by liquid metal Induction welding: 74: IW Laser beam welding: 521 522: LBW Deep penetration, fast, high equipment cost Automotive industry Laser-hybrid welding: Combines LBW with GMAW in the same welding head, able to bridge gaps up to 2mm (between plates), previously not possible with LBW alone.

  4. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    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. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick (" electrode ") and the base material to melt ...

  5. 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.

  6. Shielding gas - Wikipedia

    en.wikipedia.org/wiki/Shielding_gas

    Other arc welding processes use alternative methods of protecting the weld from the atmosphere as well – shielded metal arc welding, for example, uses an electrode covered in a flux that produces carbon dioxide when consumed, a semi-inert gas that is an acceptable shielding gas for welding steel.

  7. Butt welding - Wikipedia

    en.wikipedia.org/wiki/Butt_welding

    Butt welding is performed with the Arc, TIG, or MIG welder held at a slight angle the weld if the weld is laying flat in order to achieve the least amount of porosity in the weld and also to increase the weld's strength. [1] Fillet welding make up about 80 percent of the connection despite being weaker than butt welds. [1]
