    摘要： A laser welding system for welding a component and reducing defects in the weld by ensuring uniform, laminar gas flow over a process area of the system. The laser welding system comprises a laser for welding the component, a platform for supporting the component, an enclosure surrounding the platform, a first actuatable barrier, a second actuatable barrier, an actuator, and a controller. The enclosure includes a plurality of walls, one of the walls having an inlet and another wall having an outlet. The inlet and outlet each having an opening having a cross-sectional area for letting gas flow through. The first and second barriers are configured to modify the cross-sectional areas of the openings when actuated. The actuator is configured to actuate the barriers, and the controller is configured to direct the actuator to actuate the barriers so that the cross-sectional area of the first opening is larger than the cross-sectional area of the second opening so that a pressure at the inlet is greater than a pressure at the outlet.

    摘要： Provided is a lens assembly. The lens assembly includes a first optical path offset assembly (33), a second optical path offset assembly (34), a drive mechanism, an elastic seal ring (35) and a locking mechanism (37). The optical path of the first optical path offset assembly and the optical path of the second optical path offset assembly communicate with each other. The first optical path offset assembly and the second optical path offset assembly are each rotatable about the central axis of the lens assembly (3). The drive mechanism is configured to drive the first optical path offset assembly to rotate about the central axis. The elastic seal ring is configured to make the first optical path offset assembly and the second optical path offset assembly rotate together. The locking mechanism is pressed against the first optical path offset assembly or the second optical path offset assembly to enable the first optical path offset assembly and the second optical path offset assembly to rotate relative to each other. The lens assembly enables an offset laser beam to be further offset or be rectified, and thereby the size of a light spot can be regulated in a more diversified manner and with a higher precision. Also provided is a laser welding head. The laser welding head includes the preceding lens assembly.

    摘要： A laser processing device includes a nozzle attached to a laser processing head and including an emission hole through which a laser beam is emitted, an optical element configured to directly face the emission hole when the laser processing head is at a predetermined position, a nozzle inspection device including an image pickup device for picking up, through the optical element, an image of the emission hole viewed from a direction of an optical axis of the laser beam, a gas blowing unit for blowing a gas toward the optical element, and an operation control unit configured to cause the gas to be blown from the gas blowing unit toward the optical element before the image pickup device picks up the image after the laser processing head is moved to the predetermined position.

    摘要： An additive manufacturing system may include a build surface, one or more laser energy sources, and an optics assembly. Exposure of a layer of material on the build surface to laser energy from the optics assembly melts at least a portion of the layer of material. A gas flow head is coupled to the optics assembly and defines a partially enclosed volume between the optics assembly and the build surface. The gas flow head includes a gas inflow through which a supply gas flows into the gas flow head, a gas outflow through which a return gas flows out of the gas flow head, and an aperture arranged to permit transmission of the laser energy through the gas flow head to the build surface. The supply gas and return gas define a gas flow profile within the gas flow head.
