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.
