2.6 Welding Systems
2.6.1 Principle of Operation
Thermoplastic parts are welded ultrasonically by applying high frequency vibrations to the parts being
assembled. The vibrations, through surface and intermolecular friction, produce a sharp rise in temperature
at the welding interface.
When the temperature is high enough to melt the plastic, there is a flow of material between the parts. When
the vibrations stop, the material solidifies under pressure and a weld results.
Most plastics welders operate at a frequency above the range of human hearing (18 kHz) and are thus
called ultrasonic.
2.6.2 Weld System Applications
2000X weld systems can be used for the following applications:
• Ultrasonic welding
• Cutting and sealing thermoplastic fabric and film
• Staking, spot welding, swaging, and degating thermoplastic parts
• Other ultrasonic processing applications
2.7 Glossary of Terms
The following terminology may be encountered when using or operating a 2000-series ultrasonic welding
system. Some of these terms may not be available in all Controls (Power Supply model) configurations:
AB Amplitude: The amplitude at the horn face during the afterburst step.
AB Delay: Time delay between the end of the hold and the start of afterburst.
AB Time: The time duration of the afterburst.
