Abstract
An airfoil includes an airfoil body portion that has a pressure side and a suction side. A recessed area in the airfoil body portion is located on one of the pressure side or the suction side. At least one rib divides the recessed area into at least one geometric shape. A cover encloses the recessed area and includes at least one pedestal that engages a distal end of at least one rib. A weld extends through the cover and a portion of at least one rib. The weld spans a width of the distal end of at least one rib.
