<p><P>PROBLEM TO BE SOLVED: To provide a laser light welding method for members for glasses where, in a state in which a second metallic member 2 is stood on a first metallic member 1, laser light is emitted from the direction of the second metallic member 2, so as to weld a joint between both the metallic members, wherein uniform joining strength can be obtained without requiring high irradiation precision, and also, welding efficiency is high. <P>SOLUTION: In a state where the second metallic member 2 is stood on the first metallic member 1, from the direction of the second metallic member 2, the position of the focus of laser light is separated from the position of the joint S2, thus the joint S2 is set in the irradiation region of the laser light, and is irradiated with the laser from the state. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
