선박 건조에서 자동 블록 용접을 위한 경량모델 기반 용접선 생성

초록

The welding process is the most time and cost consuming process and the quality of welding is also an important issue in shipbuilding. In order to improve these problems, welding automa tion robots are widely used. In general, the information of weld lines is received from the CAD system for welding automation in shipbuilding. In this study, we propose a method of generat ing weld lines for block assembly using a lightweight model that is already used in various pro cesses in shipyards. The lightweight model is made for visualization purposes and has no information other than triangular elements. The shape is determined using the angle with the adjacent element, the part type is defined, and the ship coordinate system is converted into the working coordinate system. The sections are divided considering the workable range of the welding robot, and the welding lines are generated according the sections. This proposed method has been tested on several real models to demonstrate the feasibility.
