Abstract: The work described here is part of a larger experimental and theoretical program directed at obtaining a better understanding of the mechanics of flame bending. A capability for predicting the ...

Abstract: Induction heating for stress improvement (IHSI) is a method for reducing the tensile weld induced stresses on the inner surfaces of the girth welded pipes. The process entails inductively heating ...

Abstract: The accuracy of a destructive, experimental method for the evaluation of through-thickness residual stress distributions is investigated. The application of the method is to a welded pipe that ...

Abstract: Intergranular Stress Corrosion Cracking (IGSCC) has been a problem in Boiling Water Reactor (BWR) piping systems. One method for retarding IGSCC is to eliminate tensile residual stresses at the ...

Abstract: Girth welding can produce tensile residual stresses on the pipe inner surface. Because tensile stresses enhance the possibility of stress corrosion cracking, methods for altering the weld-induced ...

Abstract: A fracture mechanics analysis for an intermediate size pressure vessel is described. The vessel was tested as part of the Heavy Section Steel Technology program at Oak Ridge National Laboratory. ...

Abstract: An analysis procedure for computing residual stresses due to weld repairs of heavy steel sections is described and illustrated. The model has several unique features for weld repair applications. ...

Abstract: In this paper, a computational model is developed to calculate the magnitude and distribution of residual stresses for multipass girth-butt welded pipes. The model consists of two parts, a ...

Abstract: Recent approaches to controlling stress corrosion cracking in welded 304 stainless steel pipes have been based on various types of controlled heating procedures. When applied properly, the heating ...
