electric welding See 1.arc welding. See 2.resistance welding. Electric Welding a group of welding methods that use electric energy to heat a metal. Electric heating makes it possible to produce temperatures that exceed the melting points of all existing metals. Such heating does not alter the chemical composition of a material and is easily controlled and automated. Dozens of varieties of electric welding are distinguished according to, for example, the method of protecting the metal from oxidation, the shielding gases and fluxes used, and the extent of mechanization and automation.
