Updated pipe welding work cell from Tecnar ROTOWELD pipe welding work cells have been used in the pipe spool prefabrication industry for more than 20 years. Specifically developed for industrial pipe pre-fabrication, small pressure vessel manufacturing or other similar 1G welding, Rotoweld integrates machine vision, adaptive control and robotics technology in a dedicated package that produces high quality GMAW full penetration 1G girth welds, at five times the rate of manual SMAW. The new Rotoweld 3.0 is the result of the re-engineering of all aspects of the machine, including mechanical design, servo-controls, computer and software, taking advantage of the latest technologies. The most visible change is the robotised manipulator, which provides increased flexibility for torch positioning in various machine configurations. full penetration girth welds with just a few hours of training. Operating like the welder’s eyes and hands, the control loop continuously analyses the image of the root weld pool. Image processing algorithms use the image to adjust welding parameters such as travel speed, wire feed rate, arc voltage or weaving width, constantly adapting the process to varying conditions (gap, alignment, root face and temperature). Rotoweld 3.0 is de- signed with a modular Tecnar’s Rotoweld has been fully re-engineered

architecture, allowing users to select different configurations and processes such as SAW or FCAW, to better suit operators’ needs. A new, low-cost base model delivers the same quality welds on the full pipe size range as the previous version, but at lower productivity rates.

The core of the Rotoweld technology is its patented vision-based penetration control loop. It allows any operator, even without welding experience, to perform
