Subjects related to strength and durability of structures such as oil and gas transmission pipelines areof great importance. Considering the special characteristics of these structures including their construction and harsh working environment, they are especially prone to different types of damages. Repair welding is a viable optiontomitigatesuch damages and for restoration of the strength and resistance of these structures. In this paper, anumerical coupled thermo-mechanical finite element modelling approachis conducted tosimulatethewelding and the repair welding process. The results of the studyshow that repair weldsmay wellhave adverseeffects on the residual stress magnitudeand on its distribution. This might in turnpotentially put the integrity of the pipeline at risk. |
