LASER DEVICE FOR PERFORMING AN ANNULAR CIRCUMFERENTIAL WELDING ON A WORKPIECE USING OPTICAL REFLECTORS

摘要

A laser device (10) is provided for performing an annular circumferential welding on a workpiece (14), and includes a laser head (16) having a laser source (20) configured for emitting a laser beam to perform welding around an outer circumferential target area (12) of the workpiece (14). Also included is an optical reflector assembly (24) having at least two optical reflectors (26, 28) spaced from the workpiece (14) for reflecting the laser beam emitted from the laser head (16). The reflectors (26, 28) are spaced from each other, disposed on opposite lateral sides of the workpiece (14), and inclined relative to an axis transverse to a longitudinal axis of the workpiece (14) so that the circumferential weld is achieved by a single cycle of the laser beam.
