Abstract
A method of assembling a turbine bucket is provided. The bucket includes a dovetail portion, an airfoil portion, and a root that extends between the airfoil portion and the dovetail portion. The turbine bucket includes a pressure side and a suction side that are connected together at a leading edge and a trailing edge. The method includes forming at least one pocket within the turbine bucket, such that the pocket is formed within the pressure side. The method also includes forming at least one pin within the at least one pocket.

A method of assembling a turbine bucket having a dovetail portion, an airfoil portion, and a root that extends between the airfoil portion and the dovetail portion, the turbine bucket including a pressure side and a suction side that are connected together at a leading edge and a trailing edge, said method comprising:
- forming at least one pocket within the turbine bucket, such that the pocket is formed within the pressure side and such that the pocket includes an adhesion area;
- forming at least one pin within the at least one pocket;
- and
- applying a fill material to the adhesion area such that the fill material is bonded within the at least one pocket.
