摘要：
To study the distribution of the welding temperature field and residual stress of corrugated steel web girders, a 3D finite element model is constructed using Simufact Welding software. The welding temperature field and residual stress of the model's T-shaped joint are predicted, and the simulation results are verified by experiments. The distribution of the welding temperature field of the corrugated steel web beam is related to the center distance of the molten pool, and the closer the center of the molten pool, the greater the temperature gradient. The longitudinal residual tensile stress primarily dominates the welding residual stress. The horizontal residual stress is relatively low, showing a blend of tensile and compressive stresses. Changes in welding speed and base plate thickness do not affect the distribution pattern of residual stress but only the peak value of stress. The numerical simulation results align well with the experimental data, proving the reliability of the numerical simulation. © 2024 Editorial Board of Journal of Harbin Engineering.
