Imparting the energy is discontinued after the first energy director (107) is substantially melted and the object (133) is properly positioned, while the second energy director (125) is not substantially melted.

A second energy director (125), having a slower characteristic melting rate than that of the first energy director (107), is positioned between, and is in contact with, the second end (124) and the second member (123).

The energy incident on the lower beak may be reflected from a lower beak energy director (e.g., a reflector) or it may be provided a separate energy source.

A multifaceted energy director (15) is provided for joining two plastic workpieces (12, 14) by an ultrasonic welding method.

A method for joining at least two ultrathin plastic pieces, including the multifaceted energy director, is also provided.

The control system is preferably a control system for power transmission technology or power distribution technology.
