Abstract
The present invention is a method for seaming a polymeric material. The method involves forming an interface between a plurality of separate polymeric sheets of materials. Next, heat and pressure are applied to facilitate the diffusion of the polymer molecules at the interface. A diffusion weld is made when the polymer molecules diffuse across the interface.
