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.
