LASER WELDING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240286221 titled 'LASER WELDING APPARATUS
Simplified Explanation: The patent application describes a laser welding apparatus designed to prevent fumes from adhering to its protective optical member by controlling the flow of gas around the workpiece.
- The apparatus includes a protective optical member, upper-side gas supply unit, and lower-side gas supply unit.
- The protective optical member has a plate-like part and a cylindrical part extending downward to guide gas flow.
- The upper-side gas supply unit has first ejection ports to direct gas to the center of the plate-like part and second ejection ports to release gas downward.
Key Features and Innovation:
- Protective optical member with a unique design to prevent fume buildup.
- Upper-side gas supply unit with specific ejection ports for controlled gas flow.
- Lower-side gas supply unit for additional gas supply and management.
Potential Applications: This technology can be used in industrial laser welding applications where fume management is crucial for maintaining optical clarity and efficiency.
Problems Solved: The technology addresses the issue of fumes adhering to the protective optical member during laser welding, which can reduce visibility and affect welding quality.
Benefits:
- Improved optical clarity during laser welding processes.
- Enhanced efficiency and quality of welds.
- Reduced maintenance and cleaning requirements for the protective optical member.
Commercial Applications: This technology could be valuable in industries such as automotive manufacturing, aerospace, and electronics production where precise and clean laser welding is essential for product quality.
Questions about Laser Welding Apparatus: 1. How does the unique design of the protective optical member prevent fumes from adhering to it? 2. What are the specific advantages of using the upper-side gas supply unit with different ejection ports for gas flow control?
