Description
Summary:TIG welding is the most important process, which is used in the aircraft industry. A number of components of airplane are made using this method. Thermo-mechanical models are needed to understand better phenomena involved in this process. In the presented work thermo-mechanical simulations were performed and the possibilities of welding distortion in the investigated process were evaluated. Comparison of the results of numerical simulation with the experimental data confirmed good predictive capabilities of the model and quite good description of the phenomena involved in this process. Spawanie metodą TIG jest jedną z ważniejszych metod używanych w przemyśle lotniczym. Wiele komponentów samolotu powstaje dzięki tej metodzie. Model termo-mechaniczny wspomnianego procesu jest konieczny do dokładnej analizy zjawisk powstających podczas procesu. W prezentowanej pracy opracowano model termo-mechaniczny w kontekście analizy deformacji spawanych elementów. Porównanie otrzymanych wyników na drodze symulacji z wynikami eksperymentalnymi wykazało poprawne odwzorowanie zjawisk zachodzących podczas procesu spawania.
