detecting a defect inside a bore of the metallic part wherein the defect represents a departure from an intended geometry of the bore, the bore having a diameter and defining a longitudinal axis, and wherein the defect is located within the bore at a depth of at least greater than one said diameter along the longitudinal axis;
measuring a geometry of the defect;
preparing a patch with a complementary geometry to fill the geometry of the defect;
placing the patch in the bore with the complementary geometry of the patch seated against the geometry of the defect;
directing a welding beam from outside the bore, through the bore and onto the patch to weld the patch to the bore; and
removing a portion of the patch to provide the intended geometry for the bore.
