wind tower seam weld inspections; and bond testing of silicone coatings on high-voltage power line insulators. Ultrasonic flaw detectors (Figure 3) are also widely used in critical safety-related ...

Continuous ultrasonic welding presents the flexibility crucial for future lunar and deep-space missions, but also for defense ...

An understanding of ultrasonic welders helps designers apply this assembly method efficiently. The last two decades have seen substantial improvements in ultrasonic plastic-welding machines.

First used to bond toy parts in the 1960s and widely used in the automobile industry starting in the 1980s, ultrasonic welding is used to weld myriad plastic elements together. See ultrasonic.

Here’s something that may be of interest to all the reprappers, vacuum formers, and other plastic fabbers out there: ultrasonic welding of plastics. If you’ve ever wanted to join two pieces ...

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 ...
