Abstract
A laser welding apparatus for joining a first member and a second member together by laser welding includes: a first laser beam applying device that applies a laser beam to a border area between the first member and the second member; and a second laser beam applying device that applies a laser beam to a laser beam application spot of each of the first member and the second member, the laser beam application spot being located ahead of a laser beam application spot to which the laser beam is applied by the first laser beam applying device, in a laser welding forward direction.
Claims9
A laser welding apparatus for joining a first member and a second member together by laser welding, the laser welding apparatus comprising:
- a first laser beam applying device that applies a first laser beam to a border area between the first member and the second member;
- and
- a second laser beam applying device that applies a second laser beam to a second laser beam application spot of each of the first member and the second member, the second laser beam application spot being located ahead of a first laser beam application spot to which the first laser beam is applied by the first laser beam applying device, in a laser welding forward direction,
- wherein the second laser beam application spot to which the second laser beam is applied by the second laser beam applying device is distanced from the border area to which the first laser beam is applied by the first laser beam applying device.
A laser welding method for joining a first member and a second member together by laser welding, the laser welding method comprising:
- a first laser beam application step of applying a first laser beam to a border area between the first member and the second member;
- and
- a second laser beam application step of applying a second laser beam to a second laser beam application spot of each of the first member and the second member, the laser beam application spot being located ahead of a first laser beam application spot to which the first laser beam is applied in the first laser beam application step, in a laser welding forward direction,
- wherein the second laser beam application spot is distanced from the border area.
