The database of underwater welding technical information has been released via RIO-DB (Research Information Data Base) which is an AIST (National Institute of Advanced Industrial Science and Technology) project. In addition to this, the database of underwater cutting technical information is released. Authors are getting and saving the experimental data which is necessary for making practical underwater processing in the case of construction, repair and removing of ocean rig. As result, a lot of movies of the welding and cutting have been stored. This information is required to be opened to the public as multimedia database. We construct this database as case collections of processing including images of welding and cutting phenomenon. In this paper, we describe outline of database, progress of construction and development in future.
