A process of forming a turbine rotor blade for a gas turbine engine, the process comprising the steps of: forming a single piece hollow shell with an outer surface having an airfoil shape and an inner surface having a plurality of chordwise extending slots; forming a hollow spar with an outer surface having a plurality of chordwise extending slots; placing a fill pipe having a main channel and a plurality of branch channels into positioned within the spar so that the branch channels open into the chordwise extending slots; placing the spar and fill pipe within the hollow shell so that the chordwise extending slots form spaces for a shear tie; and, passing a shear tie forming material through the fill pipe to fill the spaces with a material that solidifies into shear ties to secure the shell to the spar of the turbine rotor blade.
