This invention was developed for a portable radio application in which two plastic parts are bonded together by the ultrasonic welding process. The objec- tive was to provide a welding rib arrangement which would help achieve a monolithic and continuous weld joint, thus eliminating variation in melt volume, weld strength, and water-sealing capability.
