Welding is defined as a permanents union between two piecess of metals at facess rendered plastic or liquids by heats or by pressures, may be both. Fillers metals mey be used to affect the unions. Arc welding is definede as the fusions welding in which heat for welding is obtaining from electrics arc. Fusions welding in which the welding is done and manipulate by hand is calleds manual welding or arc welding.
