Abstract
We introduce a method for designing manufacturing shapes for the structural parts of a ship that considers the weld-induced deformation. In this study, the design shape of a bracket was counter-deformed using a purely geometric method rather than a thermo-elastic method. The deformation quantities were estimated based on data captured in the field, and a manufacturing design shape was obtained by counter-deforming an original design shape using the proposed geometric deformation method. The proposed method was implemented and tested in a shipyard.
