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.
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 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.
