Tubular Sections

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.

Arc Welding Process

Pyramidal three-roll bending is widely used in manufacture due to its simple configuration and advantage for thick plate roll bending. However, there remain two planar zones near the front and rear ends of the bent shape. A mecano-welding process which provides improved circularity of the bent shape is proposed in this paper. This process includes three sub-processes: the first sub-process is the roll bending from a plate with cylindrical rolls; the second sub-process is the gas metal arc-welding process used to join the gap of the bent tubular section; the third sub-process is the rerun roll bending of the welded shape. Results of the numerical simulation of the first two sub-processes under the well-known ANSYS and ANSYS/LS-DYNA environment are reported. The bent shape after the first roll bending, the distributions of the temperature and residual stress after the welding are illustrated and discussed.
