The purpose of Deliverable 5.2 is to characterize in-depth the corrosion behaviour of the optimised sheet and tubular joints for each material combination. The optimized sheet and tubular joints were exposed to two complementary corrosion tests, namely salt spray testing and immersion testing. After performing the corrosion investigations, both the corrosion test specimens and not-exposed (so-called “blank”) test specimens were tested destructively by means of metallographic examination and lap shear testing. The purpose was two-fold: firstly, to compare the load bearing capacity prior to and after the corrosion damage and secondly, to compare the corrosion sensitivity of the test specimens. Corrosion testing of the sheet welds have been completed and the results are detailed in this deliverable. Compressive testing and the immersion testing of tubular welds are still ongoing. The results are expected at the end of March. The corrosion results of the tubular welds achieved so far are already presented in this deliverable.
