Abstract

PURPOSE: To enable an operation of uniform heating, and make an improvement to quality and productivity, by rotatably supporting an electrode, placing the electrode placed in a reducing gas atmosphere and irradiating a laser beam to an emitter material.
CONSTITUTION: A conveyor 2 of a transfer device 1 is intermittently driven by a driving mechanism 3 correspondingly to the pitch of a support base 4. A vessel 9 is filled by a reducting gas from a supply pipe 10. When the conveyor 2, is stopped to a support member 5 which has reached a loading position A, are one by one mounted unfired electrodes a to each of which an emitter material is adhered. The electrodes are then conveyed through a slotted portion 11 into the interior of the vessel 9 and finally reach an irradiation position C, where the support member 5 is rotated by a driving unit 7, and an electrode coil (c) is irradiated by the laser beam from an oscillator 12. In this way, an operation of heating and firing is performed uniformly and in a short length of time, and quality factor and productivity can thus be improved.
