Abstract
Due to their very high specific strength, the proportion of 7000 series aluminum alloys in vehicle bodies is steadily increasing. However, in the artificially aged condition T6 the materials generally exhibit a limited formability. The aim within the project is to improve the joinability of high-strength aluminum alloys in mechanical joining processes by a process-adapted and locally limited heat treatment and to control the material flow in order to improve the joint properties. The use of laser radiation as a heat source enables the application of heat treatment layouts in the size of the joint and thus the adjustment of locally different properties.
