Hot spot (IIW), Haibach and CAB methods for stress evaluation welded structures with FEA | PrePoMax

The Hot spot method is most popular tool to defining weld in FEA. The weld geometry is modeled with a 45° chamfer. Because of singularities at the weld transition, the hot spot stress is described using two or three stress values at specific reference points. A simplification of the hot spot method is provided by Haibach's method. He suggests that the stresses are evaluated between 2-3 mm before the weld transition. And the CAB method was developed at the University of Dortmund, in Germany - by the Chemical Apparats Construction working group. The weld is replaced by a radius.
