Tensile and bending tests modeling have been undertaken for various welded joints
which were different in shape and design. Also, the hot spot stress was calculated at critical
failure areas using the finite elements analysis method. There was a go
od similarity
between experimentally defined critical areas in certain certified literature and those in our
modeling. It appeared that the information listed in the international institute for welding
(IIW) in regards of hot spot stress method gives relatively accurate values for the welded
joints possibility to endure fatigue loading and keep their desired mechanical properties
even those joints that could fail only at the connecting area with the base metal.
