Welding is always accompanied by a heat treatment of the base metal. The heat affected zone (HAZ) of multilayer welded joints often shows different microstructures along the fusion line due to varying heat treatments. In order to investigate the mechanical properties of single microstructures weld simulation treatment was applied. The influence of weld simulation parameters such as heating rate and peak temperature was checked in a preliminary step. Several weld simulation treatments finally were used to explain the behaviour of real welded joints. A comparison of fracture mechanics test results from weld simulated microstructures and from real HAZ's shows good agreement for equal heat treatment conditions.
