Understanding of Laser Welding Phenomena

By using simulation to investigate the influence of process parameters on the laser weld pool, within stipulated process windows, it allows for optimization of certain geometrical constraints. In this way material configuration and combinations can be selected to optimize e.g. strength, which in turn results in lower weight and lower fuel consumption and less environmental impact.

The elaborated manufacturing method provides the prerequisites for better quality and lowered cost. Swedish aero-engine industry is today focusing on fabricated load carrying static structures allowing a more flexible design and manufacturing. The development of the manufacturing method and its automation require a comprehensive understanding of the complete process. The purpose of the project is to gain deeper process understanding and thus optimization capability.
