Abstract: Vibratory welded connections are formed between first and second members (32, 33) of thermoplastic material by interposing a junction piece (47) of similar material and vibrating the junction piece (47) at high speed while pressing the first and second members (32,33) in a controlled manner against opposite sides of the junction piece (47). Friction created by the vibration generates heat which melts a small amount of material at the engaging surfaces which upon cooling provides a strong welded joint having minimal flash. Entire frame systems such as window-frames can be fabricated by an apparatus system (120) which forms a friction welded joint between adjacent ends of the frame members (134, 135, 136, 137). Furthermore the frame can be fabricated around a panel such as a glazing panel. The welded connections formed by the system do not mar the finish of the frame members and produce no unsightly flash bead requiring subsequent machining steps for its removal.

Abstract: After the fixing of an angle indexing body to a holder by fixtures is canceled by loosening the fixtures, a resonator is turned by operating the angle indexing body with an axis in a vibration transmission direction as the center of rotation, a bonding work face is replaced by another bonding work face, and the angle indexing body is fixed to the holder by the fixtures so that the new bonding work face becomes parallel to the top face of a mounting table.
