Rather than using a bench mounted or special purpose ultrasonic welding machine, ultrasonic hand welding can offer great flexibility, portability and a low cost solution to your joining requirement, with only a basic level of skill required for repeatable results. Let’s discuss hand welding in further detail and examine the main benefits of this method.

Ultrasonic plastic welding is a straightforward process that can take on many unique forms. Regardless of the specific application, the fundamentals of ultrasonic welding are the same. By using ultra high frequency sound waves, plastic is heated locally via friction, and deformed to meet specifications. This process is extremely precise, and can be applied to many kinds of plastic. The materials are bonded without adhesives or the application of heat. While there is a very small amount of heat generated by the process, the equipment relies on sound waves, not direct heating, to create the weld.

Ultrasonic welding is a relatively new bonding technique that is evolving all the time. Originally discovered in the 1961, ultrasonic welding uses ultra-high frequency sound waves to bond materials. The fundamental principle is extremely simple; when an ultra-fast frequency soundwave is introduced to some materials, they melt. This form of bonding technology is unique because of the control that it offers, and its ability to join dissimilar materials. It is used extensively in the aerospace, automotive, medical and plastic manufacturing industries, but in recent years ultrasonic welding has also been utilised in the manufacture of electronics as well. Because all of the heat is localised in the weld area, this method can be used to bond very fragile materials together.
