Estudo sobre tensões e distorções pós processo de soldagem, fabricação de viga caixão

Abstract

This work aims to present studies and processes for manufacturing a welded structure, with the purpose of mitigating distortions caused by the welding process. During the welding process of a component, there are mechanical phenomena inherent to the process, which need to be controlled in order to guarantee quality and efficiency of the components. During the welding process, the contractions that occur due to the input of heat and the application of a molten filler material, cause residual stresses that need to be considered and even treated throughout the process. In order to guarantee the design tolerances necessary for the manufactured component to perform, we use some sequences or alternatives. In this work we highlight solutions found and applied to the manufacturing process of a box beam, which makes up a lifting device.
