ned.
6. The process can be integrated into automated production lines.
7. Moderate operator skill level is enough.
8. The process is fast, economical and automated.
9. It is used in mass production up to 60 parts per minute.
10. It ensures increased flexibility and versatility.
11. It produces high strength joints.
12. Very thin materials can be welded.
Limitations of ultrasonic Welding :
1. Only small and thin parts may be welded.
2. Work pieces and equipment components may fatigue at reciprocating loads provided by ultrasonic vibration.
3. Work pieces may bond to the anvil.
4. It is not suitable for ductile materials since they yield under the stresses.
5. It needs specially designed joints.
6. Ultrasonic vibrations can damage electrical components.
7. Tooling costs for fixtures are high.
Applications of Ultrasonic Welding :
1. Ultrasonic welding is used mainly for bonding small workpieces in electronics, manufacturing communication devices, medical tools and watches.
2. It is used in automotive, medical and toy production.
3. It is used in health care industries due to clean welds.
4. Ring-type continuous welds can be used for hermetic sealing.
5. It is-used in sealing and packaging, aircraft, missiles and fabrication of nuclear components.
6. It is also used in armatures, slotted commuters, starter motor armatures, joining of braded brush wires, brush plates and wire terminals.
7. Ultrasonic welding is used in the automotive industry to fabricate headlamp parts, dashboards, buttons and switches, fuel filter, fluid vessels, seat-belt locks, electronic key fobs, lamp assemblies and air ducts.
8. In electronic appliances such as switches, sensors and data storage keys are fabricated using ultrasonic welding.
9. Ultrasonic welding is also used to make medical parts such as filters, catheters, medical garment and masks.
10. It is used in welding of tubes to sheets in solar panels.
11. Packing applications such as blister packs, pouches, tubes, storage containers and carton spouts can be fabricated using ultrasonic welding,
