  2. 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 joining 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 ...

  3. Shielded metal arc welding - Wikipedia

    en.wikipedia.org/wiki/Shielded_metal_arc_welding

    Fast-fill electrodes are designed to melt quickly so that the welding speed can be maximized, while fast-freeze electrodes supply filler metal that solidifies quickly, making welding in a variety of positions possible by preventing the weld pool from shifting significantly before solidifying. [29]

  4. Plasma arc welding - Wikipedia

    en.wikipedia.org/wiki/Plasma_arc_welding

    PAC differs from oxy-fuel cutting in that the plasma process operates by using the arc to melt the metal whereas in the oxy-fuel process, the oxygen oxidizes the metal and the heat from the exothermic reaction melts the metal. Unlike oxy-fuel cutting, the PAC process can be applied to cutting metals which form refractory oxides such as ...

  5. 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).

  6. Welding - Wikipedia

    en.wikipedia.org/wiki/Welding

    Welding joins two pieces of metal using heat, pressure, or both. The most common modern welding methods use heat sufficient to melt the base metals to be joined and the filler metal. This includes gas welding and all forms of arc welding. The area where the base and filler metals melt is called the weld pool or puddle.

  7. Electric arc furnace - Wikipedia

    en.wikipedia.org/wiki/Electric_arc_furnace

    The liquid metal formed in either furnace is too conductive to form an effective heat-generating resistance. Amateurs have constructed a variety of arc furnaces, often based on electric arc welding kits contained by silica blocks or flower pots. Though crude, these simple furnaces can melt a wide range of materials, create calcium carbide, and ...

  9. Underwater cutting and welding - Wikipedia

    en.wikipedia.org/wiki/Underwater_cutting_and_welding

    Shielded metal arc cutting cuts the metal by melting it with the intense heat of the arc, without burning it with oxygen, which works better for carbon steel plate less than 6mm thick and for non-ferrous and corrosion resistant metals of any thickness. [1]: Ch. 1 Underwater shielded metal arc cutting is a simple process.
