==METHODS OF ULTRASOUND ASSISTED WELDING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240335902 titled 'METHODS OF ULTRASOUND ASSISTED WELDING

The methods of ultrasound-assisted 3D printing and welding involve the use of an ultrasonic sonotrode placed on top of the solidified layer near a melt pool. The sonotrode, pressed against the solidified materials at the edge of the melt pool, transmits ultrasonic vibrations to the solidifying melt pool, reducing hot tearing and porosity formation, and consolidating the solidified materials.

* Ultrasonic sonotrode placed on top of solidified layer near melt pool
* Sonotrode pressed against solidified materials at edge of melt pool
* Synchronized with heat source to transmit ultrasonic vibrations to solidifying melt pool
* Reduces hot tearing and porosity formation
* Consolidates solidified materials under sonotrode

Potential Applications:
- 3D printing of a variety of commercially important alloys
- Welding of materials with reduced defects

Problems Solved:
- Hot tearing and porosity formation in 3D printing and welding processes
- Incomplete consolidation of solidified materials

Benefits:
- Improved quality of 3D printed and welded parts
- Enhanced mechanical properties of printed and welded materials

Commercial Applications:
- Additive manufacturing industries
- Aerospace and automotive sectors
- Medical device manufacturing

Questions about Ultrasound-Assisted 3D Printing and Welding:
1. How does the ultrasonic sonotrode reduce hot tearing and porosity formation in the melt pool?
2. What are the specific benefits of using ultrasound-assisted methods in 3D printing and welding processes?


==Original Abstract Submitted==

methods of ultrasound assisted 3d printing and welding involve the use of an ultrasonic sonotrode placed in on top of the solidified layer in the vicinity of a melt pool. the sonotrode, pressed against the solidified materials at the edge of the melt pool, is synchronized with the heat source such that it travels side-by-side with the melt pool to transmit ultrasonic vibrations to the solidifying melt pool, reducing hot tearing and porosity formation, and to consolidate the solidified materials under the sonotrode. the methods of the present invention are capable of making a large variety of commercially important alloys 3d printable and weldable.
