Claim 7:
8. A laser welding method for welding around at least a substantial portion of a circumference of a workpiece, the method comprising the steps of:
positioning and fixing a workpiece relative to an assembly; and
directing a laser beam toward the assembly in a first direction, the assembly including a first angled reflector and an optical reflector assembly, the first angled reflector being arranged at an angle to change the first direction of the laser beam so that the laser beam irradiates a front area of the workpiece, the optical reflector assembly having at least two angled mirrors positioned to direct the laser beam passing around the workpiece to reach areas of the workpiece that are not directly in the path of the laser beam,
wherein the optical reflector assembly includes a third mirror positioned to change a direction of at least a portion of the laser beam toward an area of the workpiece that is not directly in the path of the laser beam after being reflected by the first angled reflector.
