Weld strength depends on metal, electrode, process, and joint design. Proper sizing ensures weld is stronger than base metal.

  1. 1Calculate fillet weld capacity: P = 0.707×t×L×F_y (simplified)
  2. 2Butt weld strength equals base metal if properly made
  3. 3Account for loading direction and stress concentration

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Fillet weld size t=6mm, length L=100mm, steel Fy=250 MPa
ଫଳ
P ≈ 106 kN capacity
Simplified allowable stress

  • Using leg size instead of throat dimension
  • Over-sizing welds (unnecessary cost and distortion)

ବାରମ୍ବାର ଜିଜ୍ଞାସା

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.
