A Geometry-Based Welding Distortion Prediction Tool. [PDF]
Materials (Basel), 2021 The prediction of welding distortion requires expertise in computer simulation programs, a clear definition of the nonlinear material properties, and mesh settings together with the nonlinear solution settings of a coupled thermal–structural analysis. The purpose of this paper is to present the validation of an automatic simulation tool implemented in ...

Influence of welding sequence on welding distortions in pipes [PDF]
International Journal of Pressure Vessels and Piping, 2008 This paper presents a three-dimensional thermo-mechanical analysis to investigate the effect of welding sequence on welding deformations in pipe-pipe joints of AISI stainless-steel type. Single-pass TIG welding with V-joint geometry in pipes having a diameter of 274 mm and a thickness of 6.2 mm is studied here.
