Critical Constraints
- Minimum radius of 0.030 in. (0.75 mm) on all corners to eliminate stress concentrations
during welding.
- Amplitude and energy requirements are part dependent.
- Locate weld joint as close as possible to horn mating surface to avoid "far field" welding.
Notes
- Shear joints are suggested for Eastman materials.
