Abstract

Two workpieces are joined together or welded to one another by inducing movement in a first of the two workpieces or a portion thereof by means of a pulsed magnetic force, whereby the first workpiece or portion impacts onto the second of the two workpieces and the two then become joined or welded to one another.
