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.
During the 1860s and 1870s he investigated the electric arc, and he worked on this in Moscow, St. Petersburg and Kineshma. [1] Nikolay Benardos was the first to apply an electric arc to heat the edges of the steel sheets to the plastic state. [1] He demonstrated a new way of metal compounds in Paris in 1881. [1]

Plasma arc welding is an arc welding process wherein coalescence is produced by the heat obtained from a constricted arc setup between a tungsten/alloy tungsten electrode and the water-cooled (constricting) nozzle (non-transferred arc) or between a tungsten/alloy tungsten electrode and the job (transferred arc). The process employs two inert ...

Percussion welding (PEW) is an arc welding process. The heat is obtained from an electric arc produced by short discharge of electrical energy while a percussive force is applied following the discharge. The heat generated by the discharge melts a thin area of metal on the faces of the work-pieces, and as the work-pieces are impacted they fuse ...

Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant- voltage or, less commonly, a constant- current welding power supply .
