Rotoweld 3.0
Twin Bay

Get the industry’s highest productivity output

The Rotoweld 3.0 Twin Bay is all about efficiency and arc-on time. Make loading, unloading, grinding and aligning time losses disappear with the twin bay. Prepare your next spool on the second bay while the Rotoweld is completing a job on the first bay. This is how you’ll accomplish up to 300 dia inch in a single 10-hour shift.

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.
  • Separate gas shielding system for each torch
  • Robotized torch welding arm for fast and repeatable torch positioning on selected pipe diameter
  • Torches can be easily switched — optional SAW available.

Robotic welding arm

  • 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
  • Optional fillet weld for slip-on flanges.

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 laying 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 80 ft. (24.4 m). You can upgrade a Single Bay Rotoweld to a Twin Bay.

High-torque rotators

  • Minimal set-up time required due to its self-aligned design
  • Specifically designed for the Rotoweld to have total control of the weld puddle
  • Diameter capacity: 3 in. to 42 in. / 75 mm to 1,065 mm
  • Centre line clearance to ground: 65 in. /1,605 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.

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
  • A hand pump connected to the hydraulic cylinder levels the pipe section easily, efficiently and safely
  • Heavy-duty steel idler rolls allow the pipe to turn freely. Optional rubber idler rolls are available for stainless steel application.
  • Diameter range: 3 in. to 42 in. / 75 mm to 1,065 mm
  • Load capacity: 10,000 lbs. / 4,535 kg

User Interface features:

  • UI entirely browsable with the Rotoweld pendant
  • Large centred image of the torch in the bevel (arc-off) and the weld puddle (arc-on)
  • User and Engineering modes easily toggled with the engineering lock key
  • Welding program visible at all times with a live cursor that indicates the progression of the weld
  • Expandable menus to enter key information
  • Welding information display.


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 degree 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 joint preparation
    • Displays the temperature measurements and waiting times between passes for temperature-sensitive material.
