In transverse fillet welded joint, the size of weld is equal to
Minimum area of the weld or throat area,
A = Throat thickness x Length of weld
A = 0.707 s x l
The transverse fillet welded joints are designed for
Direction of load in transverse fillet welded joint is perpendicular to the length of weld, so weld is designed against tensile stress.
The parallel fillet welded joint is designed for
Loading is along the length of parallel fillet weld, so the parallel fillet welded joint is designed against shear strength.
The size of the weld in butt welded joint is equal to
In case of butt joint, the length of leg or size of weld is equal to the throat thickness which is equal to thickness of plates.
The stresses in welded joints are difficult to determine because of following variables and unpredictable parameters, except
Stress concentration factor for welded joints subjected to fatigue loading is highest in
A plate 100 mm wide and 12.5 mm thick is joined with another plate by a single transverse weld and a double parallel fillet weld as shown in below figure. The maximum tensile and shear stresses are 70 MPa and 56 MPa respectively. What is the length of each parallel fillet weld for static loading?
For a parallel load on a fillet weld of equal legs, the plane of maximum shear occurs at
Which of the following process is not used for increasing the fatigue strength for a welded joint?
A 60 mm long and 6 mm thick fillet weld carries a steady load of 20 kN along the weld. The shear strength of weld material is equal to 200 MPa. The margin of safety is
