RF Welding vs Ultrasonic Welding: A Comparison
When it comes to joining components together, there are two primary methods of welding that are widely used - Radio Frequency Welding (RF) and Ultrasonic Welding (USW). Each has its own distinct advantages and disadvantages, making them ideal for different applications. So how do you choose between RF and USW? Let's take a closer look at each to see how they compare. What is Radio Frequency welding? Radio Frequency welding is a type of non-contact joining process that uses an alternating current to generate heat. It is also known as High Frequency Welding and is commonly used in the production of items such as airbags and seat belts. RF welding uses a combination of heat and pressure to fuse two or more materials together. It is often used on thermoplastics and films but can also be employed to weld metals such as aluminum and nickel when used in conjunction with a conductive foil. What is Ultrasonic Welding? Ultrasonic welding is another type of non-contact process that combi...
