Laser-Welded Joint Body Using Continuous Hoop Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser welding methods for joining metal members require clamping, which restricts the welding area and hinders the achievement of full joint strength between the first and second metal members.
Innovation Solution
A manufacturing method and apparatus that uses a continuous supply of a hoop material pressed against a first metal member, allowing a laser oscillation system to weld the entire surface, eliminating the need for clamping and enabling comprehensive welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the second metal member is clamped to the first metal member for laser welding, then the metal members can be joined together, but the clamped portion cannot be welded by laser and joint strength cannot be maximized
Solution Approach 1:
The invention extracts and removes the clamping step from the welding process. By eliminating the clamp that obstructed laser welding in conventional methods, the entire surface of the second metal member becomes accessible to the laser beam, enabling complete welding coverage and maximum joint strength without mechanical interference
Solution Approach 2:
The invention replaces the mechanical clamping system with a continuous feeding mechanism. Instead of using clamps to hold the second metal member in place (which blocked laser access), the system uses controlled feeding to maintain position, allowing the laser to weld the entire surface without mechanical obstruction
2Strength
If the second metal member is continuously supplied while being pressed against the first metal member, then the entire surface can be welded by laser and joint strength is increased, but the manufacturing process becomes more complex
Solution Approach 1:
The invention merges multiple functions into integrated components. The feeding mechanism combines positioning, pressing, and welding support functions into a unified system, while the laser oscillation system integrates cutting and welding capabilities, reducing the need for separate clamping devices and simplifying the overall apparatus despite the continuous process requirements
Solution Approach 2:
The invention introduces dynamic control to the welding process. The continuous feeding mechanism allows real-time adjustment of material supply rate, and the laser oscillation system dynamically controls beam parameters, enabling the entire surface to be welded without static clamping while maintaining processability through automated control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances the joint strength between the first and second metal members by allowing the entire surface to be welded, improving the structural integrity of the joint body.
Implementation Method 1
causing a laser oscillation system to irradiate a surface of the second metal member placed on the first metal member with laser light to form a joint portion including a welded portion where the first metal member and the second metal member are joined together

AI summary
A manufacturing method for a joint body having a first metal member and a second metal member joined together by causing a laser oscillation system to irradiate a surface of the second metal member placed on the first metal member with laser light to form a joint portion including a welded portion where the first metal member and the second metal member are joined together includes continuously supplying the second metal member while pressing the second metal member against the first metal member, the second metal member being a hoop material, and causing the laser oscillation system to emit the laser light.
