Gleeble-2000 thermal simulation test machine was used to conduct the isothermal thermocompression deformation tests on Q235 steel. In order to ensure the accuracy of test data and the rationality of experiments, the selection of insulation time and repeatability tests were carried out. The insulation time was reasonably determined and the instrument accuracy was verified. The effects of different deformation conditions (deformation temperature, deformation degree, and deformation rate) on deformation resistance were investigated. The deformation resistance model was reasonably selected, and the model parameters were regressed using the experimental data. Through on-site data verification, the established mathematical model for deformation resistance exhibited good prediction accuracy.
