Workpiece Edge Portions TRIZ Cases
- U-Shaped Friction Stir Welding Joint to Prevent Metal Overflow
A U-shaped joint lets only the stirring pin contact the metal, reducing member damage, enabling inspection, and limiting overflow.
- Stress-Protected Groove Weld Geometry for Fatigue-Resistant Joints
A bent and machined root protrusion shifts the weld root out of the main stress flow path, improving groove weld fatigue resistance.
- Localized Welding Pad Structure for Stable Laser Weld Mating
Offset welding pads keep laser weld surfaces in contact despite dimensional variation, reducing tooling rework and clamping force.
