Ultrasonic welding is explained as the high frequency waves of vibration for an ultrasound of the piece that is being welded. The parts are placed together under a lot of pressure which creates the solidity of the weld. Plastic materials are the pieces that are usually used with this type of welding. The ultrasonic vibrations allows the welder to weld the materials together without having to use nails and bolts or other materials to bond the parts together. The vibrations are used on the thermoplastics as they melt and the vibration is like a magnet that pulls the parts together to jolt them. Ultrasonic welding is used on various types of materials; one of the main materials it is used on is metal. For metal, the welding process is known as friction welding. A welding sonotrode is a type of horn that the welding vibrations come from. The sonotrode allows the plastic cause the thermoplastic to get softer so that it can be lined up to be jointed together. Every type of material that is used for welding has a different type of strength; metal will have the strongest bond from being welded with ultrasonic waves. Ultrasonic welding is used under circumstances when there are several jobs that need to be performed. This form of welding will get the job done the quickest and it is a very successful method to use. Automotive industries and electronic companies often use this method for welding their products since they have lots of inventory involved. Metals, hard plastic, and soft plastic are all materials that can be used with the ultrasonic welding method. Nowadays since the ultrasonic welding has been so successful with welding the above mentioned materials, the process is being studied to determine how well it will work with other types of materials as well. Ultrasonic has been in high demand for other products which is the reason why it must be studied. For example, there are some underwater welding schools, where everything is explained in details. For ultrasonic welding to work correctly, there have to be two pieces of materials that can be bonded together under lots of pressure. An anvil is used to place the parts where they need to go so that it can hit them for bonding. An ultrasonic stack is also needed for the sonotrode horn so that it can be set for the correct tune for the vibration. Next, an ultrasonic generator is needed with high AC power to match the stack resonance. A controller is also needed to maintain the movement of the press and the way it delivers the ultrasonic energy. In the future you can expect ultrasonic energy to be used for various other bonding projects since it has grown very popular with many manufacturing companies.
