Laser metal deposition is widely adopted for coating, reparation and 3D printing. Using COMSOL, we have developed a numerical model with full coupling of laminar fluid flow and heat transfer. The Marangoni effect is considered to capture the enhanced convective heat transfer as well as ... Per saperne di più
The heat and fluid flow calculation inside the melt pool in welding processes is a complex challenge. It can be useful to predict defects in the weld seam or to study the influence of some process parameters. Even if the required equations are mastered over the last few years, the cost ...

Additive manufacturing gathers technologies where near net shape components are produced by depositing successive layers of materials. Among these technologies, the Layer Beam Melting (LBM) process – often referred to as Selective Laser Melting (SLM) – is garnering industrial interest, ... Per saperne di più
Additive manufacturing technology is becoming more popular for the fabrication of metal products as it offers rapid prototyping and large design freedom. However, part quality of components fabricated by current additive manufacturing technology is not comparable to that produced by ... 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. Whereas for materials like steel and aluminium laser beam welding is already ... Per saperne di più
Additive manufacturing processes are increasingly used for designing metallic parts with complex geometries. The current needs are focused on the manufacturing of large-scale parts, typically of meter range. However, for such dimensions, the traditional trial-and-error methodology used ...

A one-dimensional model of Excimer Laser-Annealing of amorphous silicon layers which are irradiated with a KrF excimer laser is described. For realisation, the application mode heat transfer in solids is used. The model predicts a melt threshold for the energy density of the laser of 88 ... 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
Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... Per saperne di più
COMSOL Multiphysics® is being utilized to develop Thermal Model for Wire Directed Energy Deposition Additive Manufacturing (Wire-DED) process with an objective to analyse the heat transfer phenomenon during and after the process. Wire-DED process’s growing industrial acceptance at a very ... Per saperne di più
