Abstract
A method and an apparatus for friction stir spot welding together at least two metal sheets is described. A tool comprising a stepwise decreasing diameter towards the welding end is used. Each stepwise decrease in diameter defines a shoulder. The first shoulder is situated at a distance (x) from the welding end which is larger than zero and smaller than the minimum thickness (Wmin) of one of the metal sheets, and wherein a higher number of shoulders than the number of metal sheets to be joined, are situated within a distance (L) from the welding end that is smaller than the maximum thickness (Wmax) of a metal sheet times the number of metal sheets to be joined minus one.
