Mecano-welding process for tubular sections is proposed for manufacturing wind towers. It would be achieved by welding several cylindrical segments produced through roll bending. The first stage is the roll bending from a plate with cylindrical rolls. During the second stage the gas metal arc-welding is used to join the gap of the bent tubular section. The purpose of this research is to model and simulate the process under the well-known ANSYS and ANSYS/LS-DYNA environment, to analyze the residual stress distribution, particularly in the welded zone. This paper presents the modeling and simulation preparation for the second stage.
