A circular plate of $200 m m$ diameter is welded to another plate by a $6 m m$ fillet as shown in figure. The maximum twisting moment that weld can resist is ____kN-m. (Use Fe410 grade of steel and shop welded)
49.5

Solution

The correct option is A 49.5
Effective throat thickness $(t_{t}) = 0.7 \times 6 = 4.2 m m$
Strength of weld per mm length $= 1 \times t_{t} \times \frac{f_{u}}{\sqrt{3} γ_{m w}}$
$= 4.2 \times \frac{410}{\sqrt{3} \times 1.25} = 795.36 N / m m$
Total length of weld provided $= π \times 200$
$= 628.32 m m$
Maximum twisting moment $= (795.36 \times 628.32 \times 10^{- 3}) \times \frac{0.200}{2} k N - m$
$= 49.97 k N - m$
