Corrosion fatigue tests at full scale on welded tubular joints and cast-steel hybrid design components
This project was part of a European Coal and Steel Community programme of research into corrosion fatigue in offshore structures. 11 welded tubular joints made of the fine-grain structural steel StE 355 were tested. Except for one test in air, all tests were conducted in artificial sea water. In addition, 4 welded tubular joints made of StE 690 and 4 hybrid nodes of StE 355 were tested, as were some 20 V-shaped cast steel specimens. Tests on the tubular joints were conducted under variable amplitude loading using the so-called Common Load Sequence. The axial loading of the two braces was conducted in antiphase. 4 tubular joints were tested under constant amplitudes. Results show that high strength steels can be used with success in fatigue stressed offshore structures when subjected to a post-weld treatment such as TIG dressing. The advantages of a hybrid design of tubular joint in rolled steel with cast steel insert in offshore constructions were also demonstrated.
