The method includes the steps of: removably positioning a first terminal edge of a first conduit portion with a first terminal edge of a second conduit portion; facing the terminal edges of the first conduit portion and the second conduit portion; aligning the terminal edges of the first conduit portion and the second conduit portion; melting at least a portion of the terminal edges of the first conduit portion and the second conduit portion; engaging the melted terminal edge of the first conduit portion with the melted terminal edge of the second conduit portion; maintaining pressure between the engaged terminal edges, thereby creating a fused joint area; and removing at least a portion of the resultant external bead extending around the fused joint area. A fusion apparatus for employing this method is also disclosed.
