Question

Two plates of thickness 14 mm and 16 mm are to be joined by a double - V groove weld. The effective length of joint is 160 mm. The strength of weld is ________ kN. Assume that Fe410 grade steel plates are used and that the welds are shop welded.

Answer 1

In the case of double - V groove weld, complete penetration takes place

$\text{Throat thickness = Thickness of thinner plate}$
$=14mm$

Strength of weld
$=t\times l_{eff}\times \frac{f_y}{{\gamma }_{mw}}$

$=14\times 160\times \frac{250}{1.25\times 1000}kN=448kN({\gamma }_{mw}=1.25\text{for shop welding})$
