Additive manufacturing is attracting more and more interest. Laser Cladding is one of these additive manufacturing processes. As it is a blown powder process, here a melt pool formation & fusion by moving the laser beam, into which powder is blown and molten & surface tension gradient ... Read More
Laser technologies such as welding, cutting and metal deposition are widely used in the industry. High quality requirements regarding process products cause that there is often a need to monitor the process. For this purpose, optical sensors integrated with a laser head are often used. ...

Laser cutting process is usually employed in machining process, however it is also applied for dismantling nuclear facilities. Contrary to mechanical processes where tools wear out quickly and are often renewed, laser cutting process is a contactless approach, therefore there is no ... Read More
Laser material processing at micro-meter domain can be used for a plethora of applications such as micro drilling, micro welding, micro cutting, micro-texturing as well as micro polishing. These processes are governed by the time varying, complex melt hydrodynamics courtesy of melting ... Read More
This study explores the significance of the recoil pressure, Marangoni convection and surface tension effects in selective laser melting of Ti-6Al-4V. A pragmatic two dimensional model with appropriate powder distribution over a substrate of finite thickness has been developed in COMSOL ... Read More
Autoliv Livbag is a company specialized in the development and manufacturing of gas generator for airbags based on pyrotechnic and compressed gas technologies. In this context, specifications of the product are very particular. Indeed, the gas generator needs to be airtight for several ... Read More
Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... Read More
A numerical model of laser welding process applied on highly optically reflective and thermally conductive materials such as copper has been developped. The latter considers multiphysical couplings of CFD, heat transfers and phase-field representation to account for topological ... Read More
Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon ... Read More
In this paper, we present a study of the simulation of Directed Energy Deposition (DED) Additive Manufacturing (AM) using a multiphysics approach. We use a combination of Heat Transfer in Fluids, Solid Mechanics and Laminar Flow physics to accurately simulate the DED process. The ... Read More
