Ultrasonic Theory 2.5.1 What Is an Ultrasonic Weld? Ultrasonic welding joins metal parts by applying the energy of high frequency vibrations onto the interface area between the parts to be welded. 2.5.1.1 How Does It Work? Electrical Energy is transformed into high frequency mechanical vibration. This mechanical vibration is transferred to a welding tip through an acoustically tuned horn.
The power required to initiate and maintain vibration (motion) during the weld cycle can be defined as: Table 2.1 Calculating Power Where: • P = Power (watts) P = F x A x f • F = Force * (N) •...
Figure 2.3 Weld Power Graph for clean components, dirty components and when part is missing 2.5.5 Power The converter/booster/horn, (stack assembly), requires minimal electrical power to initiate and maintain motion (vibration) at a ‘no-load’ condition. As the mechanical load increases, the power required to maintain the mechanical vibration also increases. The maximum power required during a weld cycle is ‘Peak Power’.
2.5.6 Time The time required to deliver the necessary energy is defined as the Weld Time. For most welds, the time required will be less than one second. If more energy is required and all other weld parameters are maintained, the weld time will increase (Figure 2.5).
Figure 2.7 Amplitude’s Influence on Weld Power and Time 2.5.8 Resonant Frequency The ultrasonic tooling acts as a spring having node points and anti-node points. The mechanical energy used to vibrate the tool is created by the converter. As the vibrations are propagated through the acoustical tool, a harmonic resonance is established consisting of nodes and antinodes.
Page 32
NOTICE Electronic circuits in the system will protect the power supply if an overload condition exists. 2.5.10 Welding to Time In specific applications, ‘Welding To Time’ may be desired. As previously mentioned, there are three primary variables that interact; they are: •...
Terminology Actuator: A mechanical device which houses the converter/booster/horn (stack) assembly in a rigid mounting and is utilized to move the stack up or down. This allows for precise control of welding pressure while delivering mechanical vibrations from the ultrasonic stack to the work piece(s). After Burst: A short duration (burst) of ultrasonic energy that begins after completion of the AFTER BURST DELAY.
Page 34
Energy: Energy is the area beneath the ultrasonic power curve and is calculated in joules, (Watts X Seconds = Joules). When the ultrasonic welding system is setup in the “Weld In Energy” mode the system will deliver the amount of energy as programmed. NOTE: The maximum (default) time allowed for delivering ultrasonic energy is five (5) seconds.
Page 35
Power Supply (Ultrasonic): An electronic device that converts 50/60 cycle electrical current into 20 kHz, (20,000), 40 kHz (40,000), or 60 kHz, (60,000) cycles per second high frequency electrical energy. Power Supply Overload (Ultrasonic): The point or limit at which the amount of power in watts, required to keep the ultrasonic stack in motion, exceeds the available power from the power supply.
Shipping and Handling The Ultraseal 20 actuator is a system of metal and electro-pneumatic components that move the ultrasonic tooling in the ultrasonic welding system and control aspects of the weld process. Many of its components can be harmed if the unit is dropped, shipped under improper conditions, or otherwise mishandled.
