Question

A fillet - welded joint is shown in the figure. The size of the weld is 8 mm, safe stress in the weld is 120 N/mm${}^2$. The safe force to which the weld can be subjected will be ________kN.

Answer 1

$\text{Throat thickness}=0.7\times \text{Size of weld}$

$=0.7\times 8=5.6\text{mm}$

$\therefore$ Safe force

$=(80+60+80)\times 5.6\times 120\times {10}^{-3}kN$

$=147.84kN$

As thickness of plate is not given so no need to check for gross area yielding.
