Home » Steel Structures » Steel structures miscellaneous » Question

A fillet-welded joint of 6 mm size is shown in the figure. The welded surfaces meet at 60-90 degree and permissible stress in the fillet weld is 108 MPa. The safe load that can be transmitted by the joint is

1. 162.7 kN
2. 151.6 kN
3. 113.4 kN
4. 109.5 kN

Correct Option: C

Throat thickness = 0.707 × size
= 0.707 × 6
= 4.24 mm
Total length of weld, l = 100 + 50 + 100 = 250 mm

Strength or main load, P = l × t × τ_vf
= 250 × 4.2 × 108 = 113.4 kN
