Ultrasonic Welding Force Calculation. The power required for ultrasonic welding. In a point of a structure the mechanical impedance is given by the ratio between the acting force and speed.
Ultrasonic welding 131132133 the most widely used welding method for thermoplastics uses ultrasonic energy at high frequencies 2040 kHz to produce low amplitude 125 μm mechanical vibrations. All ultrasonic generator manufacturers are telling the power in terms of watts. Thetechnologyhas beendevelopedto the stage where.
The main goal in this study is.
Ultrasonic welding actuators are typically pneumatic or electric driven and provide a weld force in the range of 50-750 lbs. For this article the amplitude and welding modes are considered. Due to intermolecular and surface friction heat is generated and melts the material. To achieve a constant quality the welding time is automatically adjusted.
