A simplified method of estimating welding residual stress using modified inherent strain analysis was develoed. And residual stress in a box structure fabricated by plural welded joints was evaluated using this method. Inherent strain distribution in the box structure was inferred from that of simple welded joints by using a relation between the inherent strain distribution and the welding conditions of welded joints. Residual stress in the box structure was elastically computed with actual welding sequences. The analytical results of residual stress agree well with strain-gauge measurements from a mock-up specimen. It is shown that the developed method of elastic analysis can simply compute welding residual stress in complicated welded structures with plural welded joints.
