Paano Kalkulahin si Weld Strength
Ano ang Weld Strength?
Weld strength depends on metal, electrode, process, and joint design. Proper sizing ensures weld is stronger than base metal.
Pormula
Calculate fillet weld capacity: P = 0.707×t×L×F_y (simplified)
- P
- 0 — 0
- L
- L value — Variable used in the calculation
Step-by-Step na Gabay
- 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
Mga Nalutas na Halimbawa
Input
Fillet weld size t=6mm, length L=100mm, steel Fy=250 MPa
Resulta
P ≈ 106 kN capacity
Simplified allowable stress
Mga Karaniwang Mali na Dapat Iwasan
- ✕Using leg size instead of throat dimension
- ✕Over-sizing welds (unnecessary cost and distortion)
Mga madalas itanong
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.
