The paper presents a method for the enhancement of quality and flexibility of the elastic adhesive bonding of large components with high tolerances. The main improvement of the method is based on an innovative methodology for the alignment of one component to another component, e. g. a windshield to a truck body. The alignment is realized by a calculated deformation of the one work piece immediately before the joining process, based on the actual distances between the two components and also on the emerging stresses inside the work piece due to the deformation. In the beginning the relevant fundamentals of adhesive bonding and a specification of the state of the art-technology are presented. Based on the deficits the main intention of the work is detailed, which is followed by an extensive characterization of the invented method. Several advantages by utilization of the presented approach can be achieved. These can be described as follows: Higher process stability and reliability through precise control of the joining process, essential increase of the process quality through association with standard positioning system, immediate tolerance compensation of work pieces, reduction of leaky spots and therefore reduction of manual refinishing processes, customization of joining process according to the work pieces, reduction of strains induced by handling processes. The above mentioned methodology was invented and verified through examinations on the joining process of a large windshield for trucks. In further works the transfer of method to other large components, for example sandwich elements for side panels on busses, will be promoted. Moreover the design of adapted handling devices will be worked on and an examination of process capability and quality assurance for the production will be analyzed.
