ABSTRACT
This chapter seeks to clarify the generation mechanism of welding induced buckling, and evaluate the critical buckling condition under welding. It deals with the understanding of welding buckling mechanism, inherent deformations are considered as input parameters to calculate the critical welding buckling condition with eigenvalue analysis. J. C. Wang et al. investigated welding induced buckling with an elastic analysis based on the inherent deformation. Welding, as a common joining method due to its lots of advantages, is widely employed in fabrication of ship and offshore structures. T. D. Huang et al. carried out a comprehensive assessment of fabrication technology of lightweight structures produced using relatively thin plates. In actual welding during the fabrication of ship panel, zigzag welding and intermittent welding were employed to replace the parallel continuous welding for reducing welding buckling distortion. Straightening using line heating, which was applied on the opposite side of stiffener, was also investigated to reduce buckling distortion utilizing the same computational approach.
