Abstract

The experimental determination of the optimum values of welding parameters and consequently the optimum weld quality of shipbuilding and submarine steels which can be used in the future for the improvement of the quality of already existing underwater marine systems (including oil platforms, bridge columns and ships) and for the construction of new and unfamiliar underwater sea-structures (including the submerged parts of Wave Energy Converters and Tidal Energy Converters) in many countries like Greece is an essential parameter from a technical, qualitative and economical point of view. The purpose of this study is the presentation, justification and discussion of the outputs of the welding experimental execution of three different steels (HY 100 steels, 316Ti and S355J2+N) which are currently used in shipbuilding and submarine constructions.
