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.

Plasma Arc Welding: 15: PAW Nonconsumable electrode, constricted arc Tubing, instrumentation Shielded Metal Arc Welding [5] 111: SMAW Consumable electrode covered in flux, can weld any metal as long as they have the right electrode Construction, outdoors, maintenance Submerged Arc Welding: 121: SAW Automatic, arc submerged in granular flux
A submerged arc welder used for training Close-up view of the control panel A schematic of submerged arc welding Pieces of slag from submerged arc welding exhibiting glassy surface due to silica (SiO 2). Submerged arc welding (SAW) is a common arc welding process. The first SAW patent was taken out in 1935.
Dry hyperbaric welding involves the weld being performed at raised pressure in a chamber filled with a gas mixture sealed around the structure being welded.. Most arc welding processes such as shielded metal arc welding (SMAW), flux-cored arc welding (FCAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), plasma arc welding (PAW) could be operated at hyperbaric pressures, but ...
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).
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.
The principle of laser enhanced welding is based on the interaction between the electrical arc and laser radiation. Due to the optogalvanic effect (OGE) a channel of higher conductivity in the plasma is established along the path of the laser. [1] Therefore, a movement of the laser beam results in a movement of the electrical arc.
