* Physical diagram: The load-bearing shear section of a fillet weld is its 45 The "effective throat thickness surface at the angle bisector"" (That is the green/red dotted line in the picture) . When the external load is too high, this section will crack due to stress shear.. Use GB 50017 and AISC Ultimate load-bearing specifications accurately estimate safety redundancy.
