Insertion: The process of embedding a metal component in plastic.
Interface: 1. The contact surface of two mating parts. 2. The connection between two
pieces of equipment.
Joint: The weld surfaces.
Parameter: A unique factor or element which affects the welding operation in a particular
mode.
Parameter Range: Valid range of parameters accepted for a particular setup.
Power Supply: The electronic instrument in an ultrasonic assembly system which
changes conventional 50/60 Hz electrical power into high frequency electrical power at
20 kHz, 30 kHz or 40 kHz.
Seek: The activation of ultrasonics at a low-level (10%) amplitude, for the purpose of
finding the resonant frequency of the stack.
Staking: The process of melting and reforming a plastic stud to mechanically lock a
dissimilar material in place.
Swaging: The process of capturing another component of an assembly by melting and
reforming a ridge of plastic.
Thermoplastic: A polymer which undergoes a reversible change of state when subjected
to heat.
Thermoset: A polymer which undergoes an irreversible change when subjected to heat.
Token: Token is a concept that applies to who can make a change to the preset. If the
fieldbus has gotten the token, then only the fieldbus can perform a change. However, if
fieldbus has not gotten the token (or has released the token), then the preset can be
changed by any other means, for example, via Web Page or front panel controls.
Ultrasonic Power: Presence of ultrasonic power at the horn face.
Ultrasonic Welding: The use of ultrasonic vibrations to generate heat and subsequently
melt the mating surfaces of two thermoplastic parts. When ultrasonic vibrations stop, the
molten material resolidifies, and a weld occurs.
User ID: A unique 12 character long alphanumeric ID used to keep track of user access to
the web page interface.
Weld System: A combination of components required to perform an ultrasonic operation.
Usually consists of a power supply, converter, booster, and horn, with either an actuator or
a handheld device, or in a fixed, mounted location.
