“…Several numerical [5][6][7][8][9][10][11][12][13][14][15][16][17] and experimental investigations [1,2,[18][19][20][21][22] of arc welding have been reported by various researchers. Rosenthal [23] first proposed a mathematical model of a moving heat source under the assumption of quasi-steady state; however, as many researchers have discussed, Rosenthal's analysis (that assumes either a point, line, or plane source of heat) has major error for temperatures in or near the fusion and heat-affected zones [24].…”

“…They discussed that the main driving force for weld bead surface geometry formation is the Marangoni effect. Increasingly, commercial software packages such as ABAQUS [27] have been applied to study various welding processes [14,[28][29][30]. Michaleris and DeBiccari [30] employed ABAQUS to calculate welding-induced distortion and to study the structural integrity of large and complex structures.…”

“…They showed that welding cooling rates decreases with higher welding current. Wen et al [14] developed the 2D and 3D FE models to predict welding-induced residual stresses and strains using FE package ABAQUS [27]. The heat transfer in the fusion and heat affect zones were investigated and linked to their structural analysis.…”

This article reports on a numerical and experimental investigation to understand and improve computer methods in application of the Goldak model for predicting thermal distribution in submerged arc welding (SAW) of APIX65 pipeline steel. Accurate prediction of the thermal cycle and residual stresses will enable control of the fusion zone geometry, microstructure, and mechanical properties of the SAW joint. In this study, a new Goldak heat source distribution model for SAW is presented first. Both 2D and 3D finite element models are developed using the solution of heat transfer equations in ABAQUS Standard implicit. The obtained results proved that the 2D axi-symmetric model can be effectively employed to simulate the thermal cycles and the welding residual stresses for the test steel. As compared to the 3D analysis, the 2D model significantly reduced the time and cost of the FE computation. The numerical accuracy of the predicted fusion zone geometry is compared to the experimentally obtained values for bead-on-plate welds. The predictions given by the present model were found to be in good agreement with experimental measurements.

Abstract.Welding process results in the non-uniform distribution of heat. Combined with thermal strain, plastic deformation and welding-induced distortion, it causes important problems such as failure. This study models welding process in a 12×16 split tee junction using finite element. This junction is a reinforcing branch used in the hot taping of oil pipe line. The model is studied in 3D state. This zone, i.e. heat affected zone (HAZ) is of high importance due to the existence of a severe temperature gradient and stress in the vicinity of HAZ. This study analyses single pass butt welding with a cooling time of 2700 seconds. In order to apply boundary conditions to the model, the studied structure should be in Free State according to practical procedure. The main aim of this simulation is to analyse Longitudinal and transverse residual stresses originated from co-directional and opposite-directional welding. This joint is formed of two semicircles welded to each other as linear single pass welding. Two welders simultaneously welded both sides of the pipe.
