  2. Gas metal arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_metal_arc_welding

    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. Electroslag welding - Wikipedia

    en.wikipedia.org/wiki/Electroslag_welding

    Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding, but the main difference is the arc starts in a different location. An electric arc is initially struck by wire that is fed ...

  4. Electrogas welding - Wikipedia

    en.wikipedia.org/wiki/Electrogas_welding

    The height of the weld is limited only by the mechanism used to lift the welding head—in general, it ranges from 100 mm (4 in) to 20 m (50 ft). Like other arc welding processes, EGW requires that the operator wear a welding helmet and proper attire to prevent exposure to molten metal and the bright welding arc.

    Electron beam welding: 51 511: EBW Deep penetration, fast, high equipment cost Electroslag welding: 72: ESW Welds thick workpieces quickly, vertical position, steel only, continuous consumable electrode Heavy plate fabrication, construction, shipbuilding Flow welding (previously cast welding)

  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.

  9. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
