The project methodology is structured around four pillars for developing an industrial solution for reliable FSW girth welding of pipeline materials under extreme conditions, including high temperature, high pressure and high wear: process optimisation and robustness, flaw detection and analysis, remediation measures, and validation and demonstration. Each pillar follows the same approach, combining experimental work with computational methods in an iterative process. Experiments generate data for model development and validation, while modelling supports the design of further experiments. This approach expands the knowledge base and can be transferred to other FSW applications and material systems beyond pipeline girth welding.
