Abstract [en]

Many steel structures and components are fabricated from steel plates and steel castings. The dominating joining method is welding for all kinds of transport vehicles and this paper describes briefly main problems in connection with design and fabrication of fatigue loaded structures. Design and fabrication has developed during the last 30 years and today we have tools, methods and knowledge to produce more optimised structures. Some of the work has been performed as joint work within Nordic projects and within IIW (International Institute of Welding). FE-modelling, improved design rules, knowledge about influence from defects and residual stresses, new manufacturing methods and scientific based weld quality rules are briefly discussed in this paper.
