Abstract
The present invention relates to an apparatus for laser cladding of a curved surface comprising: (a) an elongated arm having first and second ends and defining a chamber through the arm from the first end to the second end; (b) a laser delivery source connected to a focusing lens mounted in a housing within an opening on the first end of the arm for delivering a laser beam through the chamber; (c) a delivery head mounted on the second end of the arm comprised of (i) an enclosure having an inlet for receiving the laser and an outlet for delivering the laser to the curved surface, (ii) a powder nozzle for delivering a cladding powder to an inner surface of the curved surface, and (iii) a reflective surface for reflecting the laser to exit through the outlet; (d) mounting means for rotating the curved surface for the cladding of the curved surface; and (e) indexing means for moving the arm substantially parallel to a longitudinal axis of the curved surface so as to clad the curved surface during the rotation of the curved surface. Typically, the curved surface is part of the inner surface of a tube used in industrial applications.
