For a better understanding of phenomena associated to the appearance of defects in laser welding, a heat and fluid flow model is developed. This study is focused on the modeling of a static laser shot on a sample of steel. This 2D axialsymmetric configuration is used to study phenomena ... Per saperne di più
The Finite Element Method (FEM) has become an established numerical tool used for different academic and industrial purposes. It allows the prediction of weld pool geometry, thermal cycle, final distortion and residual stress field during and after fusion welding. The capability of the ... Per saperne di più
A 2D transient heat conduction model was created in COMSOL Multiphysics to simulate temperature changes in material irradiated by a KrF laser beam confined on silicon’s surface. In this paper, the obtained results are shown and discussed in case of bulk Silicon. The heat source is ... Per saperne di più
Laser beam welding is a key technology in industrial manufacturing as it combines high flexibility and the potential for automation with excellent joint quality and minimal thermal influence of the workpiece.
