A laser welding method and apparatus for welding workpieces transported by a conveyor system are presented. The apparatus includes a laser manipulator that directs a laser beam emitted from a laser generator at various predetermined angles toward predetermined positions within a laser work zone. A transport device passes workpieces through the laser work zone where the laser beam manipulator can direct a laser beam at desired interfacing portions of each workpiece to weld those interfacing portions together. The controller is programmed to cause the manipulator to weld the workpieces without halting their motion through the laser work zone. In another aspect of the invention, a pallet orientation sensor detects pallet orientation on the transport device and provides information to the controller that allows the controller to compensate for pallet orientation variations when commanding laser beam manipulator movement.
