The Effect of Plate-Plate Butt Welding Stress Distribution on the Welding Deformation

Abstract:

In this paper, the distribution of residual stress is measured which is 60mm away from the weld center with the three-dimensional magnetic measurement apparatus of HZ-21. The stress distribution of plate - plate butt welding and its influence on welding deformation are studied. The results show that, plate - plate butt of Q235B steels, the welding stress distribution of σx direction is in the direction of a curve along the seam; 24 hours after welding, the welding angular deformation increases due to the changes of welding stress, while welding angular deformation also changes the stress distribution.
