How Ultrasonic Welding Works

About How Ultrasonic Welding Works

Ultrasonic welding differs from TIG welding since it does not involve an electrode or shielding gas. Like TIG welding, ultrasonic welding can be used to join a variety of metals together. Unlike TIG, ultrasonic welding can also weld plastic work pieces, giving it a major advantage.
Ultrasonic welding, or USW, is a welding technique that utilizes mechanical vibrations above the audible range. The process is accomplished by converting high-frequency electrical energy into high mechanical motion. The mechanical motions applied along with force generate friction alheat at the plastic joint area. This causes the plastic material to melt, forming a molecular bond between the parts. This technique is fast, economical, easy to automate, and wellsuited for thermo plastic materials’ mass welding.
