Abstract

This paper presents a theoretical model to determine the superficial inside and outside residual stresses in girth weld pipes. The model is an analytical solution using geometric dimensions of the pipe, material properties and the weld procedure in order to define the residual stress distribution which was compared with the experimental measurements by x-ray diffraction method and with the results presented in other papers. The equations considering the most important variables of the problem were proposed to obtain a quick residual stress estimation in the middle of the weld metal of the joint. The proposed model is useful to preview the welding process stresses as well as allowing welding variables study sensibility and the residual stress optimization. The model considers all inherent simplification applied to the theory.
