Abstract
Construction method of a warship is quite different from a commercial ship due to the difference of ship materials, ship size and structure, and using purpose.

To make the proper decision on the welding method and conditions for a warship construction, understanding of material class, type of materials, welding positions and etc. is required. And sufficient knowledge for structural specifications and manufacturing process at each assembly stage is also the prerequisite for the decision.

Welding joints must be designed to satisfy the required strength of the part to be assembled, while the welding materials such as filler metal, flux, and shielding gases should be carefully chosen considering the base metal, welding method and welding conditions.

As for the welding procedures, welding condition such as current, volt and welding speed, preheat/postheat processing conditions should be defined to get the sound welding result.

Using database technology for the above mentioned process is a good solution because this process requires the vast knowledge and information.

The purpose of this study is to develop the welding information system for a warship construction using database technology combined to the object-oriented technology. For this task, the information of warship construction, specially related to welding technology was gathered and reviewed from an object-oriented perspective. And the efficient data model and intuitive graphical user-interface program were developed.

The developed information system covers only the midship area of PKG. In the future research, it will be expanded the entire area of PKG.
