Influences of Welding Sequence on Residual Stress of Plate Butt Welding

Abstract:

Article Preview

For the plate butt welding of the same materials with different geometry structures, the numerical simulation was adopted to analyze the influences of welding sequence on transverse and longitudinal residual stress in the process of multi-layer and multi-pass welding. The results show that when welding from the small geometric side to the large side, the peak values of transverse and longitudinal residual stress are min along the bottom or top axis of the weld. And the welding sequences of the foremost welds have little effects on transverse and longitudinal residual stress along the bottom or top axis of the weld.
