A method of assembly of fencing made of thermoplastic materials which can be easily assembled utilizing ultrasonic welding and which can include a unique configuration for the ultrasonic welding surfaces which prevents the flow of melted thermoplastic materials outwardly onto the decorative outer surfaces of the various fencing parts. Any excess thermoplastic material is designed to pass inwardly toward the longitudinally extending bore defined in the various fencing construction parts. This concept is particularly useful for attaching capping fence members which are injection molded onto structural fence members which are extruded. 1. A method for assembly of a thermoplastic fencing construction comprising:A. providing a structural fence member of thermoplastic material with a bore extending longitudinally therethrough and defining a bore opening therein and further defining an inner wall surface extending around and defining the bore and an outer wall surface oppositely positioned from the inner wall surface and facing outwardly with respect thereto with a structural securement zone defined on the inner wall surface for facilitating securement with respect thereto;B. providing a capping fence member of thermoplastic material and defining a capping securement zone thereon for placement adjacent to the structural securement zone on the inner wall surface of the structural fence member for allowing mutual securement together by ultrasonic welding together;C. providing a plurality of welding ribs to facilitate ultrasonic welding between the structural securement zone of the structural fence member and the capping securement zone of the capping fence member;D. positioning of the capping fence member extending through the bore opening and into the bore defined in the structural fence member with the capping securement zone in registration with respect to the structural securement zone and with the welding ribs positioned between the capping securement zone and the ...
