Welding Systems
2.5.1
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.
2.5.2
Weld System Applications
DCX S Power Supply 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
DCX S Power Supply weld systems typically consist of a power supply operated with a
fixed converter-booster-horn stack.
