Non Destructive Determination of Residual Stresses in the Spiral Submerged Arc Welded Steel Pipes

2016-06-17
The residual stress state has a vital effect on the performance and service life of the welded structures. Thus, development of rapid and reliable nondestructive techniques to measure residual stresses is a critical task. Various destructive or nondestructive methods exist with their advantages and limitations. This study aims to investigate the applicability of Magnetic Barkhausen Noise (MBN) method to monitor the residual stress variations in the spiral welded steel pipes. In the experimental part, API 5L X70M steel was welded by submerged arc welding technique. Variation of the surface residual stresses was detected by MBN measurements. Microstructure investigations, hardness measurements, and residual stress measurements by the X-ray diffraction method were performed.
