Abstract: Vibratory welded connections are formed between first and second members of thermoplastic material by interposing a junction piece of similar material and vibrating the junction piece at high speed while pressing the first and second members in a controlled manner against opposite sides of the junction piece.

Entire frame systems such as window frames can be fabricated by an apparatus system which forms a friction welded joint between adjacent ends of the frame members. 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.
