The fillet welds are subjected to tensile stress. The minimum cross-section of the fillet is at the throat. Therefore the failure due to tensile stress occurs at the throat section. Thus the weakest area of the weld is the throat.
One other approach is that the other parts of the weld are subjected to normal stress and shear stress. But in the throat in addition to both bending is also there which makes it weakest.
