Throat Area of Butt Weld Joint Calculation Formulas
Weld design | Throat area of butt weld A [mm 2 , in 2 ] | |
for full weld length | for load-bearing (active) weld length | |
|
| A = s L | A = s (L - 2 s) |
|
|  |  |
|
| A = s L | A = s (L - 2 s) |
|
| A = π s (D - s) | - |
Meaning of used variables:
D | tube outer diameter [mm, in] |
L | weld length [mm, in] |
s | thickness of thinner joined part [mm, in] |
| δ | weld direction angle [°] |
