Abstract
To prevent the temperature from rising locally in a closed space so as to make the temperature in an annealing furnace uniform, an apparatus and method for annealing welded parts includes an annealing furnace,which is substantially closed; a doorway,through which welded parts,are placed into and out of the annealing furnace; a carriage mechanism,for carrying welded parts on a predetermined course in the annealing furnace; infrared lamps,for heating welded parts carried in the annealing furnace; and a circulating mechanism,for circulating hot air in the annealing furnace. Thus, the annealing (distortion-eliminating) efficiency of the welded parts is improved.
