Paper Title:
Prediction and Application of Welding Residual Deformation of Steel Sheets
  Abstract

Butt laser welding experiments of Q235 sheets in different parameter conditions are conducted, and residual deformation values of the samples are measured. To predict welding deformation, heat transfer analysis is first done by FEM to obtain corresponding quasi-steady temperature data; then an equivalent model is constructed based on temperature and inherent strain theory, and bending moment values are reversely calculated through specific measured deformation values by static analysis, which are verified by a series of process experiments. In the end, the established equivalent model is applied to predict welding angular deformation of the I-beam structure. It is shown that the proposed method has a high accuracy and efficiency.
