Results are shown in impulse joining of aluminium sheets with self-pierce-riveting. Two institutes are testing impulse-riveting with different setting velocities of the punch - up to 10 m/s by using pneumatic cylinders and about 100 m/s by using a propellant charge.
One aim focus consists in riveting without a C-frame against a flat anvil instead of using a C-frame with a contoured die. So accessibility is increased and disadvantages of occurring misalignments are avoidable.
The strength properties of the realised joints are tested.
