2. Oscar Kjellberg - Wikipedia

   en.wikipedia.org/wiki/Oscar_Kjellberg

   He invented the coated electrode used in manual metal arc welding (Swedish Patent: 27152, June 29, 1907), by dipping a bare iron wire in a thick mixture of carbonates and silicates. The purpose of the coating is to generate a fume cloud that protects the molten metal from reacting with the oxygen and nitrogen (as is present in the ambient ...

6. 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.
