Abstract
The described embodiments relate generally to methods for enhancing cosmetic surfaces of friction stir processed parts. More specifically a method for applying cold spray over a weld line generated by friction stir processing is disclosed. Methods are also disclosed for blending the cold spray applied over the weld line with a cosmetic surface portion of the friction stir processed parts. In some embodiments cold spray can be used to create a cosmetic joint between various parts. Structural joints between first and second substrates may also be formed via solid state deposition. Such joints may be strengthened through use of a hidden weld, mechanical interlocking between the substrates, and/or coupling via fasteners.
