Weld Strength کا حساب کیسے لگائیں
Weld Strength کیا ہے؟
Weld strength depends on metal, electrode, process, and joint design. Proper sizing ensures weld is stronger than base metal.
فارمولا
Calculate fillet weld capacity: P = 0.707×t×L×F_y (simplified)
- P
- 0 — 0
- L
- L value — Variable used in the calculation
مرحلہ وار گائیڈ
- 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
حل شدہ مثالیں
ان پٹ
Fillet weld size t=6mm, length L=100mm, steel Fy=250 MPa
نتیجہ
P ≈ 106 kN capacity
Simplified allowable stress
عام غلطیاں جن سے بچنا ہے
- ✕Using leg size instead of throat dimension
- ✕Over-sizing welds (unnecessary cost and distortion)
اکثر پوچھے جانے والے سوالات
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.
