LASER JOINING STRUCTURE, LASER JOINING METHOD, AND LASER BEAM MACHINING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a laser joining structure, a laser joining method, and a laser beam machining apparatus by which stable joining is made possible without excessively damaging the members to be joined.

SOLUTION: The joining method includes: irradiating the end part of a light absorbing material held between a first joining member and a second joining member with a laser beam; jetting the fused light absorbing material from the end to the outside of it and solidifying the light absorbing material; and joining the first joining member to the second joining member.
