Transmitted ultrasonic energy through welding parts to welding area, local high temperature will happen due to high acoustic resistance between two welding interface places with a certain pressure, it makes fusion to one unite. When ultrasonic stop function, and keep the pressure sustain to make its solidification molding, finally forming a strong molecular chain, which achieve the purpose of welding.
Ultrasonic spotwelding is used predominantly when, for instance, flat mouldings without weld preparation (ED) have to be welded (e.g. semi-finished products, thermoformed, blow moulded, extruded and large-surface mouldings).
Composite sonotrodes with interchangeable tips are available as standard spot welding components. Tip shape selection and use is quick and simple, allowing for items with a 3 mm thickness to be soldered this way. The bottom layer can be thicker than the top one. The spot binding process is versatile, fast and easy to use, with a manual handgrip that facilitates maneuverability.
