PURPOSE: To realize an efficient production by passing an aluminum rod, at a rate within a predetermined range, through a heater tube at a temperature within a predetermined range, annealing the aluminum rod and then electrically welding a lead wire to one end of the aluminum rod thereby eliminating defective welding. CONSTITUTION: An aluminum rod 1 is pressed, at one end thereof, to form a flat part 2 and then the aluminum rod 1 is passed at a rate of 15-20mm/sec, by means of a shooter at an air transfer section 7, through a heater tube 5 heated at 450-5O deg.C by means of a heater 6 in a heating unit 8 thus annealing the aluminum rod 1. Subsequently, a lead wire 3 is electrically welded, at a welding section 4, to one end of the aluminum rod 1 thus forming an electrode terminal 10 for electrolytic capacitor. This structure eliminates defective welding and realizes an efficient production with enhanced workability. |
