Work piece having self-supporting gusset and method related thereto

摘要

A powder-derived, non-finished work piece includes a first body section that has a wall that spans in a vertical direction. The wall has a relatively thin thickness with respect to a length and a width of the wall. A second body section is arranged next to, but spaced apart from, the first body section. A gusset connects the first body section and the second body section. The gusset extends obliquely from the wall of the first body section with respect to the vertical direction such that the gusset is self-supporting. The first body section has a geometry that corresponds to an end-use component exclusive of the gusset.

主权项

1. A method of making a powder-derived, vane structures, the method comprising:
depositing multiple layers of powdered material onto one another; joining the layers to one another with reference to computer design data relating to a particular cross-section of a work piece that is to be produced, wherein the joining of the layers forms:
a first body section including a wall spanning in a vertical direction and having a relatively thin thickness with respect a length and a width of the wall,a second body section next to, but spaced apart from, the first body section, anda gusset connecting the first body section and the second body section, the gusset extending obliquely from the wall of the first body section with respect to the vertical direction such that the gusset is self-supporting, and the first body section having, exclusive of the gusset, an airfoil; subjecting the airfoil to a post-power processing process; and after the post-power processing removing the gusset to produce a finished vane structure.
