[0002] In the shipbuilding process, segmented construction is an important component. Each product structure is composed of plate structure welding. During the product structure welding process, large welding deformation is prone to occur, which will have a significant impact on the quality of subsequent product structures and further affect the assembly accuracy of the entire hull construction.

[0003] In the past, product structural welding only had before and after structural welding. If construction personnel wanted to monitor the main parameters of the welded structure, they could only measure data when there was no welding construction and the components had cooled down. It was impossible to achieve synchronous real-time monitoring of welding. The state of the components after structural welding had become fixed. If it was found that the structural installation precision dimensions did not meet the requirements, the weld of the original structural welding needed to be removed, and then the structural installation dimensions needed to be adjusted for secondary welding, which made structural repair difficult and time-consuming, seriously affecting product production efficiency.

[0004] Therefore, in the process of welding structures such as plates, how to monitor the deformation amplitude caused by welding in real time, so as to take corresponding strain measures in time, so that the installation accuracy in the welding process of product construction structures can be controlled, high-quality and efficient, has become an urgent problem to be solved.

According to different indicator lights, the ship structure welding deformation reaction device can intuitively detect the adverse changes in the structural welding process and take timely countermeasures to correct them, so as to achieve controllable quality of the ship structure welding process and solve the technical problem that the deformation amplitude caused by welding cannot be monitored in real time at this stage.
