Developments in the field of laser beam technology over the past 20 years have enabled many industry sectors, such as the automotive industry, to significantly reduce distortion and thus to considerably increase part quality. At the same time the level of automation in manufacturing was increased. This knowledge in the fields of process technology, that is welding, dimensioning and designing of such joints, process equipment und last but not least quality assurance is to be transferred within the research project QuInLas according to the specifications of shipbuilding. However, shipbuilding makes high demands on such an automated production system in particular due to large sheet thickness as well as large part dimensions. Within the scope of the research undertaking QuInLas novel and highly innovative laser-based laser beam joining processes are developed. To be able to apply this process for welding three-dimensional ship sections, in parallel a revolutionary production system is developed, that uses seeing industry robots that can spot parts and hence allow for a high degree of automation in the welding process. Moreover, the dimension of the production system is adapted to the requirements of maritime industry and, with length of 30 m, width of 10 m and height of 8 m, considerably exceeds common portals. Furthermore, this productions system will hold process diagnostic that documents data and information required for classification already whilst producing. In addition, by means of this production system it will be possible to realize new and so far infeasible design solutions of ship engineering and to verify their structural durability in maritime application. Within the presentation objectives and results as well as their potential for laser supported manufacturing of innovative ship building and civil engineering constructions will be presented. |
