For a 20-kHz ultrasonic-welding process, for example, polystyrene (PS) requires 15 to 20 m ... This calibration lets a numeric value for the welding parameters of trigger force, ...

Ultrasonic welding, including the single-parameter weld modes, let electronics manufacturers meet high levels of assembly quality, especially for products built from rigid, molded plastic components.

We then installed the ultrasonic welding end effector on an external linear axis and the resistance welding head on a linear axis inside the fuselage.” “We led the development of the welding, ...

This article describes the process of ultrasonic welding and describes systems used for the process. ... All welding parameters are automatically controlled and adjusted which protects the acoustic ...

Ultrasonic welding is based on high-frequency vibrations (typically between 20 and 40 kHz) that cause surface friction and viscoelastic heating at the weld. The most important process parameters are ...

Ultrasonic metal welding, which came into broad use around 1990, lends itself extremely well to joining the often thin, fragile, and dissimilar nonferrous materials that are essential to advanced ...

While resistance welding uses Joule heating inside an electrically conductive carbon fibre implant, melting the thermoplastic matrix and forming a strong weld, ultrasonic welding uses high frequency ...

Continuous ultrasonic welding at DLR: “This process control at SAM|XL is also true for DLR’s continuous ultrasonic welding process, were we monitor all parameters from the generator (i.e. amplitude, ...
