Method and casting core for forming a landing for welding a baffle inserted in an airfoil

A casting core for forming a first landing for welding a first baffle inserted into a cooling cavity of an airfoil, said casting core comprising:

• a first landing portion in the shape of the first landing, the first landing portion including a laterally-extending first step portion being configured to mold the first landing as a spanwise-facing surface of the airfoil relative to an airfoil span direction onto which a first baffle is welded providing a spanwise locating surface for the first baffle, the first portion disposed at one of an outer platform end or an inner platform end, the outer platform end and the inner platform end disposed at opposing longitudinal ends of the casting core;
• and
• a cooling cavity portion extending longitudinally between the outer platform end and the inner platform end;
• the first landing portion extending substantially perpendicularly laterally from the cooling cavity portion;
• wherein the surface on which the first baffle is welded extends laterally outwardly from the cooling cavity portion.
