Fully Automated Welding Workcell Developed Specifically For Industrial Pipe Pre-Fabrication

Rotoweld 3.0 Video

Watch on TecnarChannel youtube icon website tecnar
  The Rotoweld is a fully automated work cell developed specifically for industrial pipe prefabrication, small pressure vessel manufacturing or other similar 1G welding. It integrates machine vision, adaptive control and robotics technology in a completely dedicated package that produces high quality full penetration 1G girth welds, five times faster than manual SMAW.

  Configured for easy set-up and operation, the work cell will process spools from 4" to 42" in. diameter and up to 80' in length. Typical Rotoweld configurations include two separate workbays and rotators to maximize the workcells throughput by allowing re-loading of one workbay while welding in the alternate one.  The motorized welding carriage travels between workbays along a continuous track system that also guides the idler rolls to maintain perfect alignment along the full length of the machine.
  The Rotoweld is also available in a single workbay, low cost, version that delivers the same high quality welds on the full pipe size range.  Thanks to its robotized manipulator, the same welding torch, wire-feeder and power source can be used to perform both the vision controlled root pass and all subsequent fill passes.  Furthermore, using electronic mass flow controllers, the Rotoweld can mix its own gas, a very useful feature in some areas where mixed gas is not easily available.
  The core of the Rotoweld technology is its unique, patented, vision based penetration control system.  It allows any operator, even with little or no welding experience, to perform high quality girth welds with just a few hours of training.

  Operating like the welder's eyes and hands, the system continuously analyses the image of the root weld pool picked up by a video camera incorporated in the welding arm.  Unique algorithms use this information to adjust welding parameters such as travel speed, wire feed rate, arc voltage or weaving width, constantly adapting the process to varying conditions such as changes in gap, alignment, root face or temperature. The computer's fast reaction time allows the machine to work at high deposition rates and travel speeds where weld pool conditions are much too critical to be sustained by hand.
   The Rotoweld comes with thoroughly tested individual welding programs for std and heavy wall carbon steel pipe. Additional ones can easily be created. The system's user friendly operator interface allows storage, retrieval and development of programs through off-line and even "live" editing of welding parameters. Full encoder feedback drives on all major axis ensure absolute precision and repeatability of all programmed variables. The results: 90% arc-on duty cycle, 400% productivity increase and a clean, high quality weld every single time.
