What is the difference between vibration and ultrasonic welding?
In vibration welding, the amplitude is typically between 0.4 and 1.8 mm in high-frequency machines and 1.8 and 4.0 mm in low-frequency machines. The lower the amplitude, the higher the frequency. Ultrasonic welding, by contrast, uses much smaller amplitudes. Many applications use between 25 and 125 microns or 0.025-0.125 mm.
