Hypothesis: | |||
Through repeated plunging, the material does not have | |||
sufficient time to cool down, it assumes a state similar to | |||
the artificially aged state in the area of re-plunging, | |||
Repeated annealing ( following stitching joints) causes | |||
(over-) aging, | |||
The mechanical properties are affected by | |||
those temperature cycles]] | |||

❖ A functioning welding gun was developed and tested.<br /> | |||
❖ It is possible to perform intersecting stitch welds with excellent strength properties.<br /> | |||
❖ The tensile strength, ultimate plastic elongation and fatigue strength can be scaled with the stitch weld length.<br /> | |||
❖ The temperature cycles in intersecting stitched welds have a significant effect on the microstructure and | |||
hardness distribution of the welds.<br /> | |||
➢ Further mechanical improvment of the design of the welding gun <br /> | |||
➢ Installation and start-up of a robotic manufacturing cell <br /> | |||
➢ Further investigation of the mechanical properties of the joints <br /> | |||
➢ Overlap joints, variation of materials (5xxx, 7xxx alloy) <br /> | |||
➢ Further improvment/ reduction of the weld cycle time <br /> | |||
➢ Practical demonstrators (3-sheet connection, influence of adhesive,...)]] | |||
