Nondestructive Evaluation of Welding Residual Stresses in Dissimilar Welded Pipes [PDF]

Journal of Nondestructive Evaluation, 2013
This paper investigates the nondestructive capability of ultrasonic waves in residual stress evaluation of dissimilar welded pipes. Longitudinal critically refracted (L CR ) waves are employed to measure the residual stresses in a pipe-pipe joint of stainless steel 304 and carbon steel A106. Measuring the acoustoelastic constant is usually accomplished
