Today, welding utilizes a number of energy sources. These sources include gas flame, electric arc, laser, electron beam, friction, and ultra sonic. Among all of them, ultrasonic welding is touted as a very effective way of bonding two dissimilar materials to each other in a much stronger way than can be achieved by any other welding process, particularly in plastic welding. Various forms of plastics will achieve a lasting and hard to detect bond guaranteed to act more effectively thn the use of glue or other adhesive materials or even thermal press machine.

Ultrasonic welding is a process whereby mechanical energy, developed through the transformation of high frequency alternating current into mechanical vibration (by piezoelectric ceramic transducers) is transmitted through a metal tool called a horn (or sonotrode) to the interface of two overlapping surfaces to be joined, supported by a static suitable anvil, producing intimate contact and welded joint. Many of the devices and instruments in your home like cell phone parts or computer parts have likely been put together using ultrasonic welding techniques.

It is important to keep in mind that welding is a dangerous work. By wearing protective clothing and specialized welding helmets and other gear, you can greatly reduce the inherent risks of welding. Be sure to work on a dry floor. Don’t forget to wear thick rubber shoes and dry leather welding gloves.
