Residual Stresses Measurement in Various Joint Weldments

Published experimental data from residual stress measurements are generally limited or difficult to find. Experimental data in the offshore industry are even more scarce and difficult to access to. The oil and gas industry can benefit from research done in other industries. For example, the nuclear industry has published a multitude of residual stress measurements that could be beneficial to the offshore industry, gaining more understanding and confidence in the structural integrity of critical components.For the past year VEQTER Ltd has been developing a web access database for storing and comparing residual stress measurement and modelling results. This paper presents a comparison of through thickness residual stress measurement results that are published. The first case will show numerous measurements using different techniques on girth welded joints. Then, measurements on the temper bead welding processes which have been developed to simulate the tempering effect of post-weld heat treatment will be presented and compared with cladding. Finally, comparison of residual stress measurements on T-section plate fillet weld will be made.Copyright © 2013 by ASME
