Therefore the welding parameters (preheat, post welding heat treatment (PWHT), shield gas, backing gas), affecting the microstructure of the weld, also have serious affects on the fatigue properties.
The other factor, that determines the mechanical properties of the heat affected zone, is the evolving prior austenite grain size under the welding process.
Too much heat transfer could raise the size of the prior austenite grains, which can not assure good mechanical properties [6].
Martensitic microstructure in the heat affected zone (dark part is the weld metal) To examine the distribution of mechanical properties within the welded joints, microhardness measurements were made as well.
