This paper presents an experimental study and a numerical simulation of impact welding of single and double aluminium plates using a gas gun. The study shows the differences in the bonding quality of the two impacting flyer plates. In general the bonded area between the two flyer plates is less than that between the leading flyer and the target. The simulations show that the back surface of the leading plate flyer exhibits an increase in roughness after impacting onto the target. The numerical modelling in agreement with the experiment shows that the contact surface between two flyers at the time of the contact is not flat.
