FRICTION STIR ADDITIVE MANUFACTURING DEVICES AND METHODS FOR FORMING IN-SITU RIVETS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240326155 titled 'FRICTION STIR ADDITIVE MANUFACTURING DEVICES AND METHODS FOR FORMING IN-SITU RIVETS
The abstract describes a method of joining two work-pieces using friction stir additive manufacturing.
- Friction stir additive manufacturing tool is advanced along the weld line between the work-pieces.
- Filler material is deposited along the weld line and into through holes in the work-pieces.
- Through holes have openings on the top and bottom surfaces with a passageway through the work-piece.
- The method results in joining the two work-pieces together.
Potential Applications: - Aerospace industry for joining complex structures. - Automotive industry for manufacturing lightweight components. - Shipbuilding for creating strong and durable connections.
Problems Solved: - Provides a reliable method for joining work-pieces with complex geometries. - Ensures a strong and seamless connection between the work-pieces.
Benefits: - Increases efficiency in manufacturing processes. - Enhances the structural integrity of the joined components. - Reduces the need for additional finishing processes.
Commercial Applications: Friction stir additive manufacturing can be used in various industries such as aerospace, automotive, and shipbuilding for creating high-quality and durable components efficiently.
Questions about the technology: 1. How does friction stir additive manufacturing compare to traditional welding methods? Friction stir additive manufacturing offers advantages such as reduced distortion and improved mechanical properties compared to traditional welding methods.
2. What are the limitations of using through holes in the work-pieces for filler material deposition? Through holes may require additional machining processes and careful design considerations to ensure proper filler material deposition.
Original Abstract Submitted
a method of joining a first work-piece to a second work-piece is provided. each of the first work-piece and the second work-piece include a top surface, an opposed bottom surface, and a side surface connecting the top surface and the opposed bottom surface. in one aspect, the method includes positioning the side surface of the first work-piece adjacent to the side surface of the second work-piece, and advancing a friction stir additive manufacturing tool across the top surface of the first work-piece and the top surface of the second work-piece along a weld line between the first work-piece and the second work-piece. as the friction stir additive manufacturing tool advances along the weld line, a filler material is deposited along the weld line and into a plurality of through holes formed in either or both of the first work-piece and the second work-piece. each of the plurality of through holes includes a first opening on the top surface, a second opening on the opposed bottom surface, and a passageway through the work-piece between the first opening and the second opening. the method further includes joining the first work-piece and the second work-piece together.
