Abstract
A laser cladding apparatus is capable of easily collecting metal powder and improving operational efficiency. The laser cladding apparatus clads valve seats of exhaust ports formed in a cylinder head by irradiating the valve seats with a laser beam while supplying metal powder to the valve seats. The laser cladding apparatus includes: a duct connected to the exhaust ports; and a dust collector that sucks a surplus of the metal powder generated at the valve seats. The duct has a vertical part formed in a straight tube and arranged so that the axis thereof is substantially vertical, and a branched part branched from the vertical part and arranged so that the branched direction is upward relative to the horizontal direction. The dust collector is connected to the tip of the branched part.
