Special solution methods are presented for the prediction of distortion in stiffened plate fabrications, caused by butt welds and fillet welds. These methods involve strategic reduction of the many complex features embodied in full multi-physics welding simulation. In particular, an analytical method is used to replace the thermo-elastic-plastic stage of a typical full computational analysis. The aim is to provide a robust solution strategy that enables clear understanding of the effects of different welding and fabrication procedures. The approach is underpinned by full-scale practical trials, and two case studies relating to typical fabrication questions are included.
