A critical analysis on welds distortion
| Resumo: | The central objective of the present thesis is to perform an extensive analysis on weld distortion, based on a literature survey containing numerical and experimental results. The mechanisms responsible for the weld distortions are explained. Several parameters that influence the weld distortion are studied, such as the structural parameters, the base material properties and the manufacturing parameters. The relations between the parameters and the weld distortion are defined based on the literature results. Various methodologies used to prevent weld distortion as well as methods used to quantify the weld distortion are presented and described. A study on the economic impact of weld distortion is performed. |
