A critical analysis on welds distortion

Abstract

O objetivo central da presente tese é a realização de uma análise extensa sobre a distorção na soldadura, tendo como base uma revisão bibliográfica contendo resultados experimentais e de simulação numérica. São explicados os mecanismos responsáveis pela distorção. São estudados vários parâmetros que influenciam a distorção, tal como os parâmetros estruturais, as propriedades dos materiais e os parâmetros de fabrico. As relações entre os parâmetros analisados e a distorção na soldadura são definidas com base nos resultados bibliográficos Várias metodologias usadas para prevenir a distorção na soldadura, bem como métodos usados para prevenir a distorção na soldadura são apresentados e descritos. É efetuado um estudo do impacto económico da distorção na soldadura.

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.
