Claim 16:
17. A laser welding method comprising:
generating a laser beam from a laser;
collimating the laser beam in a laser welding head;
moving the collimated beam relative to a workpiece with a wobble pattern in a limited field of view defined by a scan angle of about 1-2°, the wobble movement generated within the laser head in first and second axes;
focusing the moving beam on the workpiece as the beam moves with the wobble pattern, the focusing of the moving beam performed within the laser head after moving the beam; and
moving at least one of the laser welding head and the workpiece relative to each other while moving the beam on the workpiece in the wobble pattern to perform welding.
