Title: Apparatus for a laser welding system

Abstract

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.
