Abstract
A method and apparatus for fastening two substantially coplanar edges without a weld is disclosed. The method includes: configuring a dovetail feature on a first edge; configuring a complementary dovetail feature receptacle on a second edge to receive the dovetail feature therein; disposing the dovetail feature within the complementary dovetail receptacle; and swaging an interface defined between the dovetail feature in said first edge and said complementary dovetail feature in the second edge to swage mating edges defining the dovetail feature and the dovetail receptacle at at least six swage contact points. In one embodiment the swaging is with a hollow circle punch.
