Question

A 6 mm fillet weld is provided as shown below. The safe load (in kN) that can be transmitted by the fillet welded joint is _____.


[Take permissible stress for fillet weld = 108 MPa]

Answer 1

Effective length of weld = 80 + 70 + 80 = 230 mm
Thickness of throat
$=0.7\times s=0.7\times 6=4.2mm$
$\therefore$ Safe load $=f\times l\times t$
$=\frac{108}{1000}\times 230\times 4.2\simeq 104kN$
