PURPOSE:To perform titled exact and good brazing automatically by coating pastelike Ni solder to the terminal part of a band with a dispenser then irradiating a light beam or the like thereto in a nonoxidative atmosphere and bringing a chiller into contact with the other part. CONSTITUTION:A watch band 1 is constituted of a corrosion resistant Ni alloy or dead soft austenitic stainless steel. A table 9 is moved in the direction of an arrow 13 to move the band 1 successively at a specified speed. A proper amt. of pastelike Ni solder is coated automatically and exactly only in the terminal part 2 of the band by synchronizing the operation of a dispenser 5 with the movement of the band 1. After the band is dried in a dryer 10, a light beam, electron beam or laser light is irradiated only to the terminal part 2 while a chamber 6 of a nonoxidative atmosphere is moved at a specified speed. The terminal part is heated by irradiation heat 7 and is thus brazed. A chiller 8 is brought into contact with the part except the terminal part 2 to prevent heating of said part to a high temp. |
