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 welding arm 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.
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.
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 80 ft. (24.4 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
- 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 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: 20,000 lbs. / 9,072 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.
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 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.
