Motivation<\/strong><\/h2>\n\n\n\n

Laser beam welding is an important manufacturing process for advanced materials. However, the physical phenomena occurring in the melt pool and the keyhole are highly complex and not yet fully understood. As a result, it remains difficult to reliably predict the welding process and the resulting material properties. The aim of this project is to improve the understanding of these processes through advanced numerical simulations and thereby complement experimental investigations in a targeted manner.<\/p>\n\n\n\n

Objectives<\/strong><\/h2>\n\n\n\n

The project develops numerical models that realistically describe melt pool dynamics, keyhole behavior, and solidification during laser beam welding. A particular focus is placed on predicting the solidification conditions and the resulting grain structure, as these strongly influence the final material properties. The simulations are intended to provide a deeper understanding of the underlying physical mechanisms and to establish a reliable basis for evaluating different welding parameters. They thereby provide essential information for assessing susceptibility to solidification cracking.<\/p>\n\n\n\n

Approach<\/h2>\n\n\n\n

The physical processes occurring during laser beam welding are reproduced using high-resolution numerical simulations on modern high-performance computing systems. Models for fluid flow, heat transfer, keyhole dynamics, and solidification are coupled and continuously validated against experimental measurements. This close integration of simulation and experiment enables the development of realistic models that provide a deeper understanding of the welding process and reliable predictions of the solidification conditions.<\/p>\n\n\n\n
