The applications for ultrasonic welding are extensive. Which items can be joined by welding is determined by their thickness. If they are too thick, they cannot be successfully combined. This is the main issue with traditional welding. However, ultrasonic welding can join wires, microcircuit connections, sheet metals, foils, ribbons, and mesh. This has also become a popular method for plastic welding. This process is quick and mess-free due to the high-quality technology in these welders, such as ultrasonic converters. Because of this, many industries have taken to ultrasonic welding. 

1. Computers

In the computer industry, ultrasonic welding is popular for joining wires and microcircuit connections. Manufacturers also use this process to join junctions of wire harnesses. These are large groups of wires that spread electrical signals and power. It is also used for assembling flash drives and computer disks. This is because this welding process is so fast and can churn out high quantities in a short amount of time.  

2. Automotive

The Automotive industry uses ultrasonic welding to assemble instrument panels, door panels, lamps, air ducts, steering wheels, upholstery, and engine parts. This has replaced traditional welding because more of the components used in the automotive industry tend to be plastic. Plus, this type of welding is fast, cheap, flexible, and automated. Plus, it will not cause the surface damage that car manufacturers hated about traditional welding. 

3. Medical

Ultrasonic welding is popular in the medical industry because it does not introduce foreign debris into clean rooms. It is also something that can be automated without losing precision. Therefore, it increases part quality and decreases costs. This type of welding is often used to make medical items such as arterial filters, anesthesia filters, blood filters, IV catheters, dialysis tubes, pipettes, cardiometry reservoirs, gas filters, and face masks. It can also be used to make hospital clothing. For instance, ultrasonic welding may be used to make gowns, sterile garments, and transdermal patches. This helps prevent foreign particles from entering hospitals or clean rooms and fights against infections. 

4. Packaging

The packaging industry relies heavily on ultrasonic welding. Many everyday items you use are packaged with this method. For instance, it is used for sealing containers, tubes, and blister packs. 

5. Clothing

This technology has been used to manufacture some types of clothing. It is particularly useful in swimsuits. 

Ultrasonic welding has become popular in a lot of different industries. These are just some of the industries where you may encounter parts and tools made with this process.
