Several techniques are available for joining thermoplastic composites, including resistance welding and ultrasonic welding. While resistance welding uses Joule heating inside an electrically ...

Completion of the 8-meter-long thermoplastic composite (TPC) fuselage section comprised continuous ultrasonic welding of the MFFD’s right-hand (RH) longitudinal fuselage joint (left) and resistance ...

Unlike composites made with a thermoset matrix, thermoplastic composites (TPCs) require neither complex chemical reactions nor lengthy curing processes. Thermoplastic prepregs require no refrigeration ...

The last two decades have seen substantial improvements in ultrasonic plastic-welding machines. Bench-top models feature proportional-valve controls, linear encoders, line-voltage regulation, internal ...

Traditional ultrasonic plastic welding “modes” use computerized measurements associated with each weld to control weld consistency by focusing on a single parameter or a limit most critical to part ...

To meet growing demand for reliable, compact, and aesthetically appealing wearable medical devices, manufacturers are challenged to achieve strong, precise, and particle-free welds in increasingly ...

Martin Frost – UK sales manager, Telsonic UK the wholly owned subsidiary of Telsonic AG Switzerland, talks to AZoM about the ultrasonic torsional welding. In plastic welding, conventional LINEAR ...

Ultrasonics can effectively join together thin, fragile conductive materials, such as copper, aluminum, nickel, brass, titanium, silver, and even gold, that are essential to advanced battery ...

– Ultrasonic Welding (USW) is a joining technique that uses high-frequency ultrasonic acoustic vibrations to create solid-state welds. In the electronic, computer and electrical industries, ultrasonic ...

Film radiography is often used for welding inspection in offshore and onshore pipe laying, and for checking the reliability of defect detection using ultrasonic testing. However, it can be slow and ...
