Flow3d weld provides powerful insights into laser welding processes to achieve process optimization. Laser beam welding lbw is a welding technique used to join pieces of metal or thermoplastics through the use of a laser. Process simulation was realised by use of ansys 10 software. The beam provides a concentrated heat source, allowing for narrow, deep welds and high welding rates. Heat conduction welding is used mostly to join parts with thin walls. With this illustration, you can see the process of laser welding at work.
Numerical simulations of laser and hybrid s700mc tjoint welding. As a result of the low heat input during the laser welding process, you produce virtually distortionfree workpieces and perfect seams that typically dont need postprocessing. Industrial welding requires highly reliable processes. Tutorial of the module laser beam welding simufact youtube. The software tools enable precise simulation of different processes and procedures in the manufacturing industry. Studies of temperature distribution for laser welding of dissimilar thin. Laser welding proces the laser beam provides a high concentration of energy up to 10 8 wcm2, with the ability to focus at a point with a diameter of several micrometers. In which fea software, laser welding simulation can be done. Laser beam welding lbw is a fusion joining process that produces coalescence of materials with the heat obtained from a concentrated beam of coherent, monochromatic light impinging on the joint to be welded. A finite element code using software ansys apdl has been developed.
Simufact welding also covers the simulation of additive manufacturing laser. After the welding process, residual stresses create a balanced system of inner. The software offers all functions for the complete process from importing component. The smooth, rounded weld does not need to be processed further once the laser beam welding process is complete. Simulation of the welding process, taking only a few hours on an hpc system. Its small spot size and extremely high energy density make laser welding ideal for many welding applications. Simulation of laserbased welding in the automobile and machine. When it comes to seam geometry, laser welding systems offer you more freedom than any other process. With this illustration, you can see the process of deep laser welding at work. Laser is an acronym for light amplification by stimulated emission of radiation. It is important to capture all the relevant physical phenomena to have a realistic process simulation. Electron beam and laser beam welding are very similar processes but with some critical differences that might make a big difference when it comes to which is right for your application. A basic animation to visualise the use of an inbore welding tool mounted to a robotic arm.
Laser welding is a process used to join together metals or thermoplastics using a laser beam to form a weld. It is based on keyhole or penetration mode welding. Familiarize yourself with the the functionality of the software, we will show you the gui and software usage. The process is frequently used in high volume applications using automation, as in the automotive industry. It is used when a high welding depth is needed or when different material layers need to be welded at once. I need to create a moving heat source over a plastic material. Being such a concentrated heat source, in thin materials laser welding can be carried out at high welding speeds of metres per minute, and in thicker materials can produce narrow, deep welds between squareedged parts. With deep welding, energy is also applied below the workpiece surface. Electron beam welding vs laser welding advantages and. Flow3d weld laser welding simulations process optimization.
