In view of the lack of original data in ship construction welding detection, the difficulty of centralized management of detection data and the inability to trace the source of detection results, combined with the current main detection methods of ship construction welding, the architecture of ship construction welding detection management system is designed by using cloud architecture technology. Using advanced cloud architecture technology, the ship construction welding detection management system can support multiple users to work together online at the same time。The system can reflect the digital management mode of advanced shipbuilding yard, shorten the detection application cycle of construction, reduce the hours of welding detection and management cost of welding detection, and improve the ship welding detection ability and the competitiveness of shipbuilding yard. It has played a positive role in improving the competitiveness of shipbuilding yard and promoting the digital transformation and upgrading of shipbuilding yard.
