The short answer is sometimes and under the correct conditions.
Just about any thermoplastic, and I am assuming you are talking about
thermoplastic urethane instead of thermosetting urethanes, can be
ultrasonicly welded to itself.
The trouble with urethanes is that in softer forms it takes a lot of
energy to get the two surfaces to excite enough to weld together.
Been there done that. Spent over 6 years bonding urethane systems.
There are other techniques that are prefered, if you need assistance
further drop me E-mail and we can discuss.
