The aim of the development of test methods for joint characterisation is to characterize in-depth the performance of the optimized joints for each material combination and hence generate knowledge concerning the joint properties. One of these aspects is the corrosion resistance of the joints. To this end, the optimized sheet and tubular joints will be 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 will be tested destructively by means of metallographic examination and lap shear testing. The purpose is 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. First, an overview of the material combinations tested for both sheet and tubular joints was listed. The experimental set-up and details of the corrosion tests are then described. Subsequently, a synthesis of the corrosion tests and destructive testing results for both sheet and tubular joints is presented.
