The practice of joining two thermoplastic resin bodies with widely disparate melting temperatures is enhanced by providing a shallow, roughened surface on at least the higher melting point body. When the parts are clamped together for frictional engagement, the roughened surface increases the local pressure, accelerates the formation of a molten film between the bodies and provides a strengthening mechanical interlock in the welded joint.

A vehicle lamp assembly has an opaque housing portion and a light transmissive lens portion. The housing includes a peripheral channel for accepting a sealing adhesive and a complementary peripheral tongue on the lens portion. The bottom of the channel is characterized by a plurality of energy directors which contact the tongue and are locally upset by a ultrasonic weld apparatus to provide local welding between the lens and housing. The local welding provides fixtureless retention of the respective parts during the curing of the sealing adhesive.
