Abstract: A method of fabricating airfoil cluster includes providing an airfoil cluster that has a pair of spaced-apart airfoils that extend from a common platform wall. The airfoil cluster is then divided through the common platform wall to provide separate first and second airfoil segments. At least one cooling hole is then formed in at least one of the first and second airfoil segments. The segments are then metallurgically fused together in a distinct metallurgical joint in the common platform wall.
