LASER CLADDING APPARATUS AND METHOD

摘要

A laser cladding apparatus for applying laser cladding process on a valve seat portion of a cylinder head has cylinder head-holding means (1) for holding a cylinder head (H) in an inclined manner such that the axis of a valve seat is in the vertical direction, a laser processing head (2) for irradiating a laser beam to a work portion of the valve seat and discharging a powder material to the work portion, rotating means (3) for rotating the laser processing head about the axis of the valve seat with the laser processing head inclined relative to the vertical direction, and powder material feeding means (4) for feeding the powder material to the laser processing head.
