Phantom High-Speed Camera Goes Where No Welding Camera Has Gone Before

Using cameras to monitor welding processes is nothing new. They help operators control the quality, speed and positioning accuracy of automated welding equipment in dangerous or hard-to-reach areas. That’s where Davi Ribeiro and his colleagues come in. Ribeiro is a member of the Welding Research and Technology Laboratory (LPTS), a Brazil-based research group that falls under the Department of Metallurgical and Materials Engineering at the Federal University of Ceará (UFC). The lab focuses on developing new arc welding processes (see sidebar) and utilizes a range of both manual and automated welding equipment—from grinders and cutting blades, to robotic positioning systems and specialized computer software. For the last few years, the lab has also utilized a Phantom v711 high-speed camera from Vision Research, enabling Ribeiro and his colleagues to effectively image welding joints less than 1 mm in diameter.

A High-Speed Look At Downhole Oil Well Cleaning

Thanks to Vision Research’s Phantom v2511, Olson Technologies was able to see what their Plasma Blaster does in an oil well 30 feet underground—notably, the blast reaction and liquid retraction. Whenever a detonation or blast of some kind occurs under a liquid (in this case, oil), the fluid is briefly displaced. As the oil quickly moves to refill the unoccupied space, a powerful vacuum is created, which sucks the loosened debris into the bottom of the Plasma Blaster. By utilizing the vacuum in this way, Olson Technologies removes the original source of the clog and lessens the chances that another issue will happen in the future. Keep Reading

Capturing Fast-Moving Ferrofluids On The Nanoscale

Led by Dr. Yu Gu, Assistant Professor of Physics at Juniata College, undergraduate students focused their studies on magnetic ferrofluids. The research being performed requires a Phantom high-speed camera do see the quick movement occurring in tiny capillary tubes. Using a Miro C110 mounted to a microscope in a laboratory setup. Results of the study will aid in the advancement of laboratory research capabilities and in industrial areas like semiconductor manufacturing. Keep Reading
