A Finite-Element Model for Residual Stresses and Deflections in Girth-Butt Welded Pipes

Abstract: Computational models for predicting transient temperature distributions, residual stresses, and residual deflections for girth-butt welds are described. Comparisons of predicted and measured temperatures for a two-pass welded pipe show agreement to within 9 percent and 17 percent of the measured values for passes one and two, respectively, the model for predicting residual stresses and residual deflections is based on a finite-element representation recognizing individual passes, temperature dependent elastic-… Show more

“…However, with the availability of 64 digit computers and refined FE tools, welding engineers around the world are more biased towards the computer simulations of complex welding phenomenon instead of the conventional trial and error approach on the shop floor. A significant simulation and experimental work focusing on circumferential welding is available in the literature [4][5][6][7][8][9][10][11]. As the computer simulation of welding processes is highly computationally intensive and large computer storage and CPU time are required, most of the previous research reduces computational power requirements by simplifying with assumptions such as rotational symmetry and lateral symmetry in numerical simulations [5][6][7][8].…”

“…Ueda and Yamakawa (1971) were the first among those who proposed a thermal elasto-plastic finite element model to analyze the transient thermal stresses induced in a butt joint configuration with material deposition from a moving electrode. Following this pioneering work, many researchers have successfully developed various numerical models (Ueda et al, 1986;Ueda and Yamakawa, 1971;Hibbitt and Marcal, 1973;Rybicki et al, 1978;Radaj, 1992;Luo, 1997;Hong et al, 1998;Dong, 2001;Lindgren, 2006) based on finite element method to predict temperature distribution, analyze the welding residual stress and distortion both in 2D and 3D problems. Hibbitt and Marcal (1973) developed a numerical model for the welding of a large structure by subsequent loading to the structure for high strength steels.…”
