Welding Distortion Analysis of a Laser Welded Thin Box Structure [PDF]
Journal of the Korean Welding and Joining Society, 2007 Prediction and control of the thermal distortion is particularly important for the design and manufacture of welded thin metal structure. In this study, numerical computations are performed to analyze effect of structure section shape and weld line location on distortion. In addition, this study aims to develop a thermal elasto-plastic simulation using

Review on distortion over welded structures
Analele Universităţii "Dunărea de Jos" din Galaţi. Fascicula XI, Construcţii navale/ Annals of "Dunărea de Jos" of Galati, Fascicle XI, Shipbuilding, 2019 Since welding started to be used on a large-scale basis in engineering, distortion has become a stringent problem for the industry, mostly for shipyards. This paper aims at bringing together the result of large amount of research on distortion and mitigation techniques, in order to support further practical research on the topic.

Prediction of numerical distortion after welding with various welding sequences and clampings
Metalurgija, 2010 Welding simulation of a test cover for hydropower plant was made due to very large dimensions of the cover. The main aim was to predict distortion after welding in order to avoid machining the cover. Welding process was simulated with the Sysweld program
