Abstract
A visually seamless method of joining a first piece of metal and a second piece of metal is described. The first piece of metal is placed in contact with an edge of the second piece of metal. In some embodiments, the edge includes a sacrificial lip. The first piece of metal forming a junction area with the edge of the second piece of metal, applying a forging force to the first piece of metal, the forging force having an effect of creating an extremely tight fit up between the first and the second pieces of metal, welding the first and the second pieces to form an assembly and forming a cosmetically enhancing protective layer on the surface of the assembly, the protective layer obscuring any visible artifacts on the surface of the assembly, the obscured visible artifacts including any discoloration or discontinuity created by the laser welding.
