Laser welding is well established in many industries thanks to high productivity, quality and flexibility. However, laser welding of aluminum is associated with high risk of weld defects such as hot cracks, distortion, solidification cracking and porosity. The quality of the weld depends on many variables in a huge complexity. A simulation model will be developed to predict increased risk of cracking and distortion. It will be a practical tool in the teaching as well as for material producers, engineers and welding engineers.
The project also aims to develop guidelines, in a user-friendly format, to optimize the process robustness, which will be very helpful for welders and welding engineers and save a lot of time in the development of production. The project is mainly focused on the demands of the automotive industry, but also aerospace industry (and subcontractors) is involved.
