On the interaction between welding residual stresses:a

However, the interaction of existing residual stress field with new ones imposed by fusion welding processes has received little attention to date. This study presents a numerical and experimental investigation into the interaction of bead-on-plate welds in thick plates of IN718 with the aim of evaluating the effects of pre-existing weld residual stresses on the final global residual stress distribution. Residual Stresses in Butt Welding of Two Circular Pipes The numerical results for peak transverse residual stresses attained in the welded plates for two-pass, three-pass and four-pass welded joint were 67.7 N/mm², 58.6 N/mm², and 48.1 N/mm² respectively. What is Residual Stress? - TWIThe impact of residual stresses on structural integrity (primarily fracture and fatigue) Residual stress mitigation methods (e.g. post-weld heat-treatment, peening etc) Distortion control; In addition, several past and present NSIRC projects address measurement, modelling or interpretation of various aspects of welding residual stresses.

Translate this pageNumerical investigation on weld residual stresses in tube to tube sheet joint of a heat exchanger. Crack development in weld of the tube to tube sheet region of heat exchanger is a common problem. The residual stresses associated with welding can play a major role in this situation. In this paper, the Finite Element Method (FEM) is used to predict the residual stresses in a tube to tube sheet weld.
