Laser Joining Technologies for Dissimilar Material Combinations (JODIS)

Objetivo

For the constructions of yachts and small ships the application of aluminium/steel-transition joint approaches significant relevance because of design criteria in order to reduce weight in the upper regions of the vessel. In these application fields, materials with a thickness of 5 mm are of relevant interest. At present, material combinations like aluminium and steel can only be joined by an explosively bonded steel/aluminium transition profile.
To realize a direct bonding of the dissimilar materials no commercial technology is available for the corresponding material thickness. By using an adapted laser joining technology, this problem could be overcome. For joining thin sheet material combinations e.g. steel / aluminium alloy a laser process with potential for industrial application is already available. By the localized energy input of the laser beam and a controlled heat distribution a minimized interaction of the joined materials is realized, thus avoiding embrittlement of the joint. The topic of this project is the up-scaling of the material thickness up to 5 mm focussing on the material combination steel / aluminium. Joint geometries like butt- and T-joints should be evaluated, targeting on the potential of assemblies made of dissimilar material combinations. As the implementation of expensive laser welding equipment will not be economically reasonable for small shipyards, suppliers specialized in laser welding will have to enabled by transfer of know how.
The goal of this project is the strengthening of the competitiveness of small European ship yards and their suppliers trough the implementation of advanced joining technology...
