Abstract
An improved laser weld process control system and method are provided. The system and method include a machine vision camera to detect a deviation between a pre-programmed laser beam toolpath and a gap centerpoint between first and second parts being welded together. The first and second parts are secured to a rotatable fixture, and the system and method cause the rotatable fixture to rotate through a corrective angle to bring the gap centerpoint into alignment with the laser beam toolpath, optionally in real time during the application of laser beam energy. The system and method can also correct for a vertical misalignment of the laser focal point due to rotation of the fixture by adjusting the vertical separation of the laser unit relative to the fixture.
