  • Apparatus for annealing welded parts and method therefor
    Patent number: 6294763
    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 2 which is substantially closed; a doorway 5 through which welded parts 4 are placed into and out of the annealing furnace; a carriage mechanism 6 for carrying welded parts on a predetermined course in the annealing furnace; infrared lamps 9 for heating welded parts carried in the annealing furnace; and a circulating mechanism 12 for circulating hot air in the annealing furnace. Thus, the annealing (distortion-eliminating) efficiency of the welded parts is improved.
