LASER WELDING METHOD AND APPARATUS FOR SEALING A SEED CAPSULE

摘要

The present invention state that preclude the entrance of the seed capsule cap to seal the radiation causes I-125 laser is at about the seed capsule sealing method and an apparatus to be sealed by the surface tension of the molten pool, and then melted by the laser. ; seed laser capsule sealing apparatus of the present invention the seed capsule ( 20) for chucking and rotating the spindle unit 30, the inlet 22 toward the melting edge (24) by irradiating a laser beam (B) of the seed capsule (20) for rotation by a spindle unit 30, and a laser head 40 for forming a pool (26), the seed capsules injection nozzle for injecting a shield gas (G) for preventing oxidation toward the welded part of 20 60, a laser head 40 and characterized in that the position of the main frame composed of finely to adjust 70 the head position adjusting mechanism is provided on the (80). ; Thus, the seed in a state that excludes the cap according to the invention and higher productivity due to the sealing of the capsule are possible and reduce the manufacturing cost, there is an effect that work more easily.
