Abstract
A laser welding apparatus is equipped with a laser head that emits a laser beam and an airflow forming unit that forms sheet-shaped airflows, in which the airflows formed by the airflow forming unit traverse an optical path of the laser beam emitted from the laser head, the airflows traversing the optical path at multiple positions which are spaced from each other in a direction along the optical path in a same direction. The airflow forming unit has an opening between the airflows at the multiple positions, the opening penetrating in a direction in which the airflows traverse the optical path.
Claims7
A laser welding apparatus comprising:
- a laser head that emits a laser beam;
- and
- an airflow forming unit including an emission nozzle that forms sheet-shaped airflows,
- wherein the sheet-shaped airflows formed by the airflow forming unit traverse an optical path of the laser beam emitted from the laser head, the airflows traversing the optical path at a plurality of positions which are spaced from each other in a direction along the optical path in a same direction, and
- the airflow forming unit has an opening between the sheet-shaped airflows at the plurality of positions, the opening penetrating in a direction in which the sheet-shaped airflows traverse the optical path, wherein the emission nozzle is positioned to surround the opening.
A laser welding apparatus comprising:
- a laser head that emits a laser beam;
- and
- an airflow forming unit including an emission nozzle that forms sheet-shaped airflows, wherein at least one sheet-shaped airflows formed by the airflow forming unit orthogonally traverses an optical path of the laser beam emitted from the laser head and at least one sheet-shaped airflow traverses an area parallel to or oblique to the optical path of the laser beam, wherein the sheet shaped airflows are disposed at a plurality of positions along the optical path, and
- the airflow forming unit has an opening between the sheet-shaped airflows at the plurality of positions, the opening penetrating in a direction in which the airflows traverse the optical path, wherein the emission nozzle is positioned to surround the opening.
