A method of forming an airfoil (100) includes the steps of (a) providing an airfoil body (106) with a hollow (102) having at least one rib (108) extending to an outer surface, and forming the outer surface of the rib (108) to have at least one groove (110) connecting a hollow pocket (112) within a boundary defined by the rib (108) to a location outwardly of the rib, (b) placing a cover (104) over the hollow (102), and (c) welding the cover (104) to the airfoil body (106), and such that the rib (108) is welded to the blade cover. An intermediate airfoil body (106) is also disclosed.
