Abstract

This work concerns numerical simulations of thermomechanical phenomena in laser butt-welding of sheets made of X5CrNi18-10 steel. Abaqus FEA software is used in calculations taking into account phase transformations during material’s state changes and temperature dependent thermomechanical properties of analysed steel. Additional numerical subroutines are implemented into Abaqus solver in order to describe the movable heat source power intensity distribution.The shape and size of melted zone is predicted as well as residual stress and deformations. Real butt-welded joints are executed in order to verify the results of numerical simulations. Numerically predicted deflection of the joint is compared to real displacement, measured using profile-graphometer New Form Talysurf 2D/3D 120. Melted zone of the cross section of the joint is compared to numerically predicted geometry of the fusion zone.
