| Research Abstract |
It is important for the quality of hull structures in ship-building to increase precision of manufacturing process such as cutting, welding and assembling. Weld distortion is one of the most important factors for precise manufacturing, but it was difficult to intentionally control weld distortion. A new methodology of controlling weld distortion for near-net shape manufacturing is studied by using control of temperature distributions during weld process and material properties in hull plate and weld metal.
