Welding torches and wire feeder

  • Designed with 2 welding torches: one to perform open-root-pass butt welds and the other for filling passes
  • Each torch has its own wire spools. Root pass is done in GMAW choices for fill passes: GMAW, FCAW, MCAW, SAW.
  • Separate gas shielding system for each torch
  • Robotized torch manipulator for fast and repeatable torch positioning on selected pipe diameter
  • Torches can be easily switched — FCAW and SAW are both standard in the Rotoweld 3.0 HD model.

Manipulator

  • Self-positioning of the arm in welding position in just a few seconds with no human manipulation
  • Welding vision system controls the puddle penetration and adapts welding parameters in real time
  • Embedded LED lighting allows the welder to easily align the torch in the bevel before starting to weld.

Proprietary designed rail system

  • Rails are the backbone of the Rotoweld 3.0 and can be level with any shop floor conditions
  • Rails are factory pre-assembled and pre-aligned for maximum on-site precision
  • Seamless integration; no wires lying on the ground.
  • Welding station and optional fume extractor travel on the rails to desired position simply by using the joystick
  • Twin Bay comes with 5 rails for a total length of 77 ft. (23.8 m).

Heavy-duty pipe stands

  • 4 pipe stands that can be moved quickly and easily on the rail while staying aligned with the rotator to guarantee perfect positioning
  • Powerful hydraulic lift raises the pipe to the desired height, effortlessly, efficiently and safely
  • Heavy-duty steel idler rolls allow the pipe to turn freely. Optional rubber idler rolls for stainless steel application.
  • Recovery bins designed for easier flux recovery and fast positioning under the joint
  • Diameter range: 3 in. to 48 in. / 75 mm to 1,219 mm
  • Load capacity: 15,000 lbs. / 6,804 kg

High-torque rotators

  • Minimal set-up time required due to its self-aligned design
  • Diameter capacity: 3 in. to 48 in. / 75 mm to 1 ,219 mm
  • Centre line clearance to ground: 71 in. / 1,803 mm
  • Operation speed range: 0.2 to 1.9 rpm
  • Load capacity: 3,000 lbs. / 1,360 kg
  • Maximum torque: 50,000 lbs.-in. / 5,649 n-m
  • Optional stainless steel grippers.

Prodatalog™

Gives you:

  • An overview of your productivity for a period of time that can be filtered by welder, welding programs and job number
  • A daily report in a chart that contrasts the arc-on time, the complete procedure and interruption
  • Details on each joint:
    • Displays the welding parameters used for all passes as a function of degrees of rotation
    • Displays the complete welding program that was loaded for this joint.
    • Records a live video of each pass, pushing the limits of investigating welding practices or a joint preparation
    • Displays the temperature measurements and waiting times between passes for temperature-sensitive material.
