    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 joining of the metals.

    en.wikipedia.org/wiki/Shielded_metal_arc_welding

    Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.

    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).

    en.wikipedia.org/wiki/Laser_guided_and...

    The process is used for welding thin metal sheets up to about 2 mm when welding in overlap or butt joint. LGS-GMA-welding is most advantageous when welding fillet welds. The guidance effect of the laser radiation forces the arc into the fillet. Therefore, a steady seam can be reached.
