WHAT IS ULTRASONIC WELDING?

In simple terms, ultrasonic welding uses high frequency vibrations to heat and bond two parts that are touching under pressure. These high frequency vibrations exceed the limit of human hearing in most cases. The range of human hearing is from 20 Hz to 20 kHz while ultrasonic frequencies utilized in these welders typically range from 15 kHz to 75 kHz. The technique was patented in the 60’s and first used in the toy industry. Since then, the technology continues to advance and is used in industries such as medical, electronics, packaging, and automotive. Ultrasonic welding can be used for plastics as well as metals, but this article will primarily focus on plastic welding. To better understand ultrasonic welding let’s examine the components of a welder.Welding with ultrasound is a process of combining thermoplastics or metals using the heat created through mechanical actions that operate at a high-frequency. An electrical energy with high-frequency is produced and is converted into this high-frequency mechanical motion. Applied force is used in conjunction with the mechanical motion to produce heat friction at the mating surfaces or joint areas of the metals or thermoplastics. This heat friction causes the parts to melt together, forming a molecular bond that is strengthened once the materials cool back down. In the case of metals, the heat friction raises the metal surfaces’ temperatures to around one-third of its melting point. Rather than melting the metals, the heat friction removes films and metal oxides from the metal surfaces, permitting the metal atoms to move between the surfaces and fuse the metals together.
