The invention relates to the technical field of ship equipment assembling and welding, in particular to a large stern roller flange plate high-precision assembling and welding technology for an engineering ship. The large stern roller flange plate high-precision assembling and welding technology comprises three construction processes of left and right flange plate assembly and installation carried out on a total assembling site, left and right flange plate welding and fixing and stern roller installation carried out at a dock. In the construction process carried out on the total assembling site, the left and right flange plate installation position is positioned, determined and fixedly assembled by hoisting a stern roller to the installation position in a testing mode, and left and right flange plates are welded and fixedly installed after being assembled and installed. The construction process carried out at the dock comprises the steps of hoisting and installing the stern roller and fixedly installing the stern roller through the left and right flange plates. Compared with traditional dock installation, construction procedures are implemented in advance, cross operations are few, the construction environment is improved, dock and hoisting equipment occupied time is shortened, the dock construction period can be greatly shortened, the construction efficiency is effectively improved, and the ship building cost is reduced.
