Dimensioning of laser-welded powertrain components
Components for the drivetrain are increasingly joined using laser welding. Design modifications usually need to be introduced in order to provide for sufficient weldability and guaranty component quality. Moreover, load analyses provide valuable input data for component dimensioning. We map the important fabrication steps (press fitting, laser welding) in our finite element calculations, taking into account specific material properties in the weld zone.
