Verified Approaches to Life Management & Improved Design of High Temperature Steels for Advanced Steam Plants – VALID

The project explores the link between welding process and cross-weld creep strength for CSEF steel P92 and also the relationship between specimen geometry and weld width. Five different welding processes are being used to fabricate joints in P92 to allow acquisition of data over a wide range of process parameters and demonstrate the available welding technologies to industry. This will include the development of welding equipment and consumables. A demonstration of the creep performance of welds in new experimental steels will also be carried out.
