Which of the following type of weld cannot be used for tension member?

A circular shaft of diameter 100mm is welded to a rigid plate by a fillet weld of size 6 mm. If a torque of 10 kN-m is applied to shaft, what is the maximum stress in the weld?

Refer the figure below:

Given data: size of fillet weld = 7 mm

Permissible stress in plate = 250 MPa

Permissible stress in weld = 110 MPa

Effective length of weld = 250 mm

The value of permissible load is:

The length of weld joint is 1000 mm. The thickness of plate is 6 mm. The strength of weld is reduced by a factor β_lj the value of β_lj will be:

The value of equivalent stress for a fillet weld subjected to normal (f_a) and shear (q) stresses is given by:

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

Two plate of thickness 15 mm and 13 mm are to be joint by a groove weld. Assuming an effective length of 150 mm, the difference in strength provided by single–V grove weld joint and double–V grove weld joint is–

[Assume the Fe410 grade steel plates are used and welds are shop welded]
