The influence of process support on welding deformation of large-scale structure

[摘要] For large-scale structure, it simulates welding deformation of the floor. It analyses the influence of different process support forms on welding deformation of the floor, and verifies the simulation results. The results show that the predicted results of no process support are consistent with the experimental results, and error is 8.5%. Two kinds of process support forms can control welding deformation of the floor. The simulation results of process support are consistent with the experimental results, and error is less than 14%, which proves the correctness of the finite element model. With the increase of process support, the maximum effect of controlling deformation is 32.8%.
