Question
Consider the fillet-welded lap joint shown in the figure (not to scale). The length of the weld shown is the effective length. The welded surfaces meet at right angle. The weld size is 8 mm, and the permissible stress in the weld is 120 MPa. What is the safe load (in kN, rounded off to one decimal place) that can be transmitted by this welded joint?
Correct answer
134 to 136
Solution
Given:
Weld size, mm
Permissible stress, MPa
Effective length of weld, mmFor welded surfaces meeting at a right angle (), the throat thickness is given by:
For ,
mmThe safe load that can be transmitted is:
N
kNRounding off to one decimal place, the safe load is 134.4 kN.
