Beschreibung
Zusammenfassung:	The present invention provides a process for forming a fluid tight seal between a polymeric body (18) and a polymeric dilatation member (20) surrounding the body comprising positioning the dilatation member along and in surrounding relation to the body with the dilatation member and body aligned to place a first surface portion of the dilatation member and a second surface portion of the body in a contiguous and confronting relation, generating substantially monochromatic energy at a wavelength selected to at least approximately match a wavelength of high spectral absorption of at least one of the polymeric materials forming the dilatation member and body, controllably directing the monochromatic energy onto the body and the dilatation member to concentrate the monochromatic energy in a narrow bond site circumscribing the body and running along the interface of the first and second surface portions, thus to melt the polymeric materials along said bond site and the immediate region thereof and allowing the previously melted polymeric material to cool and solidify to form a fusion bond (36) between the body and dilatation member.
