Question

Two plates of thickness 16 mm and 14 mm are to be jointed by a single- V groove weld as shown in figure.


Assume an effective length of 200 mm, Fe410 grade steel plates are used and that the weld is shop welded. The strength of the weld will be _______. [Take ${\gamma }_{mw}=1.25$]

Answer 1

$\text{Throat thickness,}{t}_c=\frac{5}{8}t=\frac{5}{8}\times 14=8.75mm$

$\text{(As full penetration of weld is not ensured)}$

Effective length weld, $L_w=200mm$

$\therefore \text{Strength of weld}=\frac{L_w{t}_c{f}_y}{{\gamma }_{mw}}$

$\text{[ For Fe410,}{f}_y=250\text{MPa]}$

$=\frac{200\times 8.75\times 250}{1.25}N=350kN$
