Welding is a popular method to join materials. Local application of a heat source on a material for a short period of time can have a tremendous effect on the microstructure of that material. If the heat source is strong enough or a filler material is used, there exist melting, solidification and heat treatment at the same time and the process can be much more complex. Our physically based simulations can shed light on the complexity of the welding process microstructural evolution.

Thermodynamic and precipitation kinetics models allow us to predict the formation and growth of intermetallic phases. Furthermore, the microstructure evolution models give information about the grain size development. These results combined with the diffusion modeling allow simulating the various regions of the material with no uniform composition. Finally, the mechanical properties of the selected product part can be estimated.

We provide welding simulations of dissimilar material parts, analysis of the base and filler material properties and predictions of the weld microstructure evolution in specific service conditions.
