Claim 15:
16. A method of filling a plurality of cooling holes in an airfoil component comprising an internal area surrounded by an outer wall, the method comprising:
injecting a curable composition into a fill channel located in the outer wall such that the curable composition flows through the fill channel to the plurality of cooling holes located on a surface of the outer wall to form a plurality of beads of the curable composition on the surface of the outer wall over the plurality of cooling holes such that a single bead is formed on each of the plurality of cooling holes;
filling any unconnected holes not in fluid communication with the fill channel with the curable composition;
directing a radiation from a radiation source located on a multi-axis arm being positional about the component and having 6 degrees of freedom to the respective beads in directions parallel to the respective central axes of the cooling holes associated with the respective beads to cure curable composition of the respective beads; wherein the directions parallel to the respective central axes are at angles of 0 to 20° of each of the central axes of the respective cooling holes; and
heating the component after directing the radiation to cure the curable composition located in the fill channel; wherein the heating of the component is conducted after the directing of the radiation to the beads; wherein the injecting comprises injecting the curable composition via an injector located in an injection hole in fluid communication with the fill channel; and wherein the method further comprises removing the injector from the injection hole while injecting the curable composition to form a final bead on the injection surface over the injection hole; and curing the curable composition in the final bead.
