Weld Strength ની ગણતરી કેવી રીતે કરવી
Weld Strength શું છે?
Weld strength depends on metal, electrode, process, and joint design. Proper sizing ensures weld is stronger than base metal.

- 1Calculate fillet weld capacity: P = 0.707×t×L×F_y (simplified)
- 2Butt weld strength equals base metal if properly made
- 3Account for loading direction and stress concentration
Worked Examples
ઇનપુટ
Fillet weld size t=6mm, length L=100mm, steel Fy=250 MPa
પરિણામ
P ≈ 106 kN capacity
Simplified allowable stress
Common Mistakes to Avoid
- ✕Using leg size instead of throat dimension
- ✕Over-sizing welds (unnecessary cost and distortion)
Frequently Asked Questions
Why is fillet weld size measured at 0.707t instead of full size?
Throat dimension (0.707× size) is the critical failure plane; leg dimension is measured size.
How does loading direction affect weld strength?
Welds strongest in shear along the weld axis; weakest perpendicular to axis.
