Abstract
Air management systems are provided for optimizing airflow in laser welding with deflectors. A system for a welder includes a blower to generate an airflow stream. A plenum receives the airflow stream, directs it toward the workpiece, and defines an outlet facing the workpiece to expel the airflow stream toward the workpiece. A deflector adjacent the outlet is formed as a conical section converging from the plenum toward the workpiece, and is defined by an angled wall with an open center. The deflector concentrates the airflow stream to impart a velocity increase to the airflow stream after leaving the outlet and to impart a favorable directional component to the airflow stream toward a weld zone, as well as protecting the laser lens by increasing the downward momentum force of the air stream to eliminate the potential of spatter impinging the lens.
