Fillet Weld Strength Calculator
Estimate static capacity of a single straight fillet weld.
Estimate static capacity of a single straight fillet weld.
PRELIMINARY RESULT
Effective throat4.24 mm
Estimated capacity: 50,904 N
- Effective throat
- 4.24 mm
- Estimated capacity
- 50,904 N
Calculation detail
Formula: Capacity = 0.707 × leg size × effective length × allowable shear stress
Static weld capacity is based on the effective throat area of one straight fillet weld.
FORMULA VERIFICATION
Units, scope and reference
Reference: AWS D1.1/D1.1M reference context; geometric throat relation for an equal-leg fillet weld.
Internal unit basis: mm² and N/mm². Outputs: N.
Valid conditions: Positive effective dimensions and source-controlled allowable shear stress.
Limitations: Not an AWS design check; excludes code qualification, eccentricity and fatigue.
