Transient out-of-plane distortion of multi-pass fillet welded tube to pipe T-joints

A Geometry-Based Welding Distortion Prediction Tool

“…Vetriselvan et al [27] reported a multipass tube-to-pipe joint. The material used here was EN-S355J2G3 steel.…”

The effect of process parameters and plate thickness on in-plane inherent deformations in T-joint fillet weld

“…The results have shown that the welding sequence has a significant effect on the distortions and residual stresses in both magnitude and distribution mode. Vetriselvan et al (2017) investigated the effect of welding sequences and directions on the out-of-plane distortions in the tube to pipe T-joints using finite element analysis and experimental measurements, it was shown that the reasonable welding directions and sequences play a positive role in reducing the out-of-plane distortions of the T-joints. Two numerical models, including butt-welding and T-joint fillet welding, were presented by Seleš et al (2018) to predict the welding-induced residual stresses and distortions.…”

“…A literature survey shows that the computational approach, especially the TEP FE analysis, has been widely accepted and used to solve many problems in welding (Jung and Tsai, 2004; Deng et al , 2007a, 2007b, 2008; Deng et al , 2010; Vakili-Tahami and Ziaei-Asl, 2013; Atabaki et al , 2014; Chen et al , 2015; Shen and Chen, 2014; Perić et al , 2014; Perić et al , 2016; Chen and Soares, 2016; Fu et al , 2016; Vetriselvan et al , 2017; Seleš et al , 2018), such as temperature field, welding deformations and residual stresses, but only for typical welded joints and small size welded structures because of its large requirement on computer memory and computing time, which makes it not a sensible choice when applied to large-scale and complex welded structures in actual engineering practice. In recent decades, a more efficient computational method, namely, elastic FE analysis with inherent strain and/or deformation and interface element, has been developed to investigate welding distortions in large welded structures.…”

“…The above-mentioned literature investigations were carried out from three different perspectives: The TEP FE analysis for T-welded joints and small size welded structures (Jung and Tsai, 2004; Deng et al , 2007a, 2007b, 2008; Deng et al , 2010; Vakili-Tahami and Ziaei-Asl, 2013; Atabaki et al , 2014; Chen et al , 2015; Shen and Chen, 2014; Perić et al , 2014; Perić et al , 2016; Chen and Soares, 2016; Fu et al , 2016; Vetriselvan et al , 2017; Seleš et al , 2018), in which the temperature field, residual stresses and welding distortions under different welding conditions and materials were mainly focused. The fast calculation methods based on inherent strain and deformation, together with local solid and global shell FE models, mainly used to predict the welding deformations for large scale and complex plate welded structures (Deng and Murakawa, 2008; Huang et al , 2016; Murakawa et al , 2012; Murakawa et al , 2009; Murakawa et al , 2013; Wang et al , 2013b; Wang et al , 2016; Wang et al , 2017; Wang et al , 2018); With regard to the analysis between inherent deformations and influencing factors, within a certain of welding conditions, it is usually limited to line heating process or bead-on-plate welding (Vega et al , 2007; Vega et al , 2010; Vega et al , 2013; Vega et al , 2015; Wang, 2012). …”
