    Abstract: A laser machine includes a housing, a machining table, a gate, a machining head, a loading/unloading door, an exhaust port, an outside air intake port, and a deflector. The housing includes a first face and a second face orthogonal to a first direction, a third face and a fourth face orthogonal to a second direction, and a fifth face orthogonal to a third direction and facing the floor surface. The exhaust port is provided on the second face and connected to an exhaust unit that generates an airflow that is a flow of air inside the housing. The outside air intake port is provided in an upper part of the housing between the first face and the machining head in the first direction, and takes in outside air. The deflector guides the outside air introduced through the outside air intake port toward the machining head.

    Abstract: A laser welding apparatus capable of eliminating or reducing a possibility that a part of air flows upward and hence fumes adhere to its protective optical member is provided. A laser welding apparatus according to the present disclosure includes a protective optical member disposed between a laser scanner and a workpiece, an upper-side gas supply unit, and a lower-side gas supply unit disposed below the upper-side gas supply unit. The protective optical member includes a plate-like part and a cylindrical part extending downward from an outer edge of the plate-like part. The upper-side gas supply unit is disposed below the plate-like part of the protective optical member. The upper-side gas supply unit includes a plurality of first ejection ports configured to eject gas to a center of the plate-like part, and a plurality of second ejection ports configured to eject gas downward with respect to the plate-like part.
