Abstract
The block assembly process is one of the most important manufacturing processes for shipbuilding. Since block is composed of several steel plates and steel sections with predetermined shapes according to ship design, the welding operation planning to construct a block is a critical activity for shipbuilding, but this activity has traditionally been experience based. Thus, it is required to develop an automated welding operation planning system to assemble blocks. This paper describes the development of an automated welding operation planning system for block assembly in shipbuilding. Based on the information about parts, topological relationship between parts and assembly sequences for block, the developed system performs the determination of welding postures, welding methods, welding equipment and welding materials. The developed system implemented successfully for real blocks constructed in shipyard.
