Abstract
After a workpiece introduced into a welding station by a feed mechanism is positioned and fixed in the welding station, the workpiece is welded by laser beams guided by scan heads. Each laser beam is applied from one of the scan heads to a location on the workpiece through a beam path switching mirror of a beam path switcher to weld the location on the workpiece. Thereafter, the beam path switching mirror is retracted to guide the laser beam from another one of the scan heads to another location on the workpiece to weld the other location on the workpiece.
