| Abstract: | The welding distortions of the main beam and side beam of expansion and contraction beam are predicted and analysed based on the welding distortion calculation method of relative shrinkage volume. And welding distortion values of experimental beams are measured. The calculation and measurement results show that the welding distortions of main beam are longitudinal shrinkage and deflection; and the welding distortions of side beam are longitudinal shrinkage, deflection and side deflection. Theoretical calculation results of welding distortions of two beams are basically compatible with the measurement results. Therefore, the researching works provide a necessary basis for the design and manufacture of welding process equipment system of expansion and contraction beam. |
