Laser beam welding apparatus
 The position of a workpiece delivered into a welding station by a feed mechanism is detected by CCD cameras of position detectors, and a positioning error of the workpiece with respect to a reference position is determined on the basis of the detected position. After training data for welding robots is corrected on the basis of the determined positioning error, scan heads on distal ends of the welding robots are inserted into the workpiece. After the scan heads have been inserted to predetermined positions in the workpiece, only the scan heads are actuated to weld the workpiece at a plurality of locations thereof with a laser beam.
