Abstract: Aspects of the disclosure include air flow systems configured to regulate air flow when laser welding to improve laser weld quality. An exemplary air flow system can include a primary inlet coupled to an air source and one or more secondary inlets coupled to the primary inlet. At least one of the one or more secondary inlets can include an internal valve. Each internal valve is actuatable between a fully open state, a fully closed state, and an intermediate state. The air flow system can further include an outlet coupled to each of the one or more secondary inlets downstream of the internal valve and a controller configured to adjust a position of each internal valve. The controller is configured to adjust the position of each internal valve based on an air flow mapping to increase an average air flow velocity along a laser beam of a welding laser.

Abstract: A method for healing surface irregularities in a weld joint includes generating a healing energy beam by a focused energy device, where the healing energy beam includes a predefined energy density. The method also includes scanning the healing energy beam along at least a portion of a periphery of the weld joint, where the weld joint includes at least an upper layer and a lower layer. The method also includes melting less than half a thickness of the upper layer of the weld joint. The predefined energy density of the healing energy beam is based on the thickness of the upper layer of the weld joint.

Abstract: A weldment assembly includes a first component and a second component configured to be coupled to the first component. Additionally, the first component and the second component are coupled through a first linear stitch and a second linear stitch disposed parallel to the first linear stitch.
