A method for securing first and second parts together via a spheroid, wherein the first part has a hole in it slightly smaller than the spheroid while the second part and spheroid each include ultrasonically fusible material. The method comprises placing the first part against the second part, placing the spheroid into the hole in the first part so that a portion of the spheroid extends through the hole and into contact with a portion of the second part, placing a concentrating horn of an ultrasonic power source in contact with the spheroid, and ultrasonically vibrating the horn to beat it against the spheroid and thus impart ultrasonic energy to both the spheroid and the second part, thereby heat-softening the spheroid and second part and causing the spheroid material to flow through the hole, fuse with the second part material, and overlap an adjacent portion of the first part, whereby the two parts, via the spheroid, are firmly secured together.
