Welding aluminium and steel welding is required in shipbuilding. The use of transition joints can be found in marine constructions. A permanent, maintenance free joint between aluminium and steel is essential. Aluminium is being used in shipbuilding to reduce weight. However, it is quite expensive and therefore not used for the complete hull.
