Abstract
A method for watertight welding, and components formed using that welding method, wherein the welding method includes providing a first component half with a groove and a protruding ridge located therein, providing a second component half with a tenon shaped to match the profile of the groove, disposing the tenon inside the groove such that the tenon contacts the protruding ridge, applying an ultrasonic power source near the groove to melt the protruding ridge, and applying opposing vertical force to the first component half relative to the second component half, such that the protruding ridge wedges in a bonding seam between an outside surface of the tenon and an inside surface of the groove.
