ROTOWELD 3.0

The Automatic Pipe Spool Welding Robot Proven Worldwide.

With over 35 years of automated welding experience and hundreds of systems in operation worldwide, Rotoweld provides a stable approach to pipe spool welding. Autoa supplies and supports Rotoweld across Australia and New Zealand, helping fabricators introduce consistent, repeatable welding into their production. The system is designed for shops that want predictable cycle times, reduced variability, and a simpler way to manage pipe spool welding.

ROTOWELD 3.0 Configurations

Explore The Rotoweld 3.0 Configurations.

The Rotoweld 3.0 Single Bay is a compact, full-capability pipe welding cell built for workshops that need accuracy and consistent productivity in a smaller footprint. It’s ideal for structural spool fabrication, maintenance work, and jobbing environments where fast changeovers matter.

The Rotoweld 3.0 Twin Bay adds a second welding station to increase throughput without expanding your floor space. It enables continuous production by letting operators prep one joint while welding the next, making it well-suited for busy fabrication shops and mid-scale project work.

The Rotoweld 3.0 Single Bay HD is designed for heavy-wall and large-diameter pipe where higher torque and strong material handling are essential. It delivers stable, repeatable welding performance for demanding industrial applications and thicker section spools.

The Rotoweld 3.0 Twin Bay HD combines heavy-duty capacity with dual-bay productivity, making it ideal for high-volume pipe welding in LNG plants, refineries, and large industrial builds. It is designed to keep thick-wall spools moving through production at pace.

The Rotoweld advantage

Automated Pipe Welding.

Rotoweld brings consistency to pipe spool welding by controlling torch position, rotation, and travel throughout each pass. The system reduces the variation found in manual welding and helps fabricators achieve predictable results with less operator input. See more on the RotoWeld website here.

Protecting The Welder

Improved Welding Conditions.

Safer Distance From The Arc.

Operators supervise the weld remotely, reducing UV exposure and direct arc contact.

Clear Camera-Based Visibility.

A live weld view allows operators to monitor every pass without leaning over the joint.

Reduced Manual Handling.

Controlled pipe rotation minimises repositioning and repetitive movements.

Lower Physical Strain.

Operators avoid extended reach, awkward positions, and heavy handling across long shifts.

Predictable, Stable Operation.

A consistent welding sequence reduces unexpected movements and operator fatigue.

Integrated Fume Extraction.

Weld fumes are captured at the source to support safer operating conditions.

PerfectPass-IQ

Automatic Welding Intelligence.

PerfectPass-iQ adjusts welding parameters in real time to suit joint preparation and changing conditions in pipe spool welding. Operators can start a weld with a single button and let the system manage root, fill, and cap passes with minimal intervention.

Prodatalog

Performance Logging.

Prodatalog records every weld completed on the Rotoweld and presents the data through a simple, web-based dashboard. Fabricators can monitor progress, review weld information, and support quality control with clear, accessible records

Frequently Asked Questions

You Ask. We Answer.

As a rule of thumb, typical Rotoweld 3.0 welding times are as follows: 

1 min/inch dia for standard wall pipes prepared with 37.5 deg bevels

1.5 min/inch dia for heavy wall pipes (again with 37.5 deg bevels)

A more precise calculation can be achieved using the formula below (valid for 37.5 deg bevel):

W = (D x0.31416) + (40 x T2 x D) / R

  • W is the welding time (minutes)
  • T is the pipe thickness (inches)
  • D is the pipe diameter (inches)
  • R is the deposition rate (lbs/h)

Typically, a welder will be fully effective with the Rotoweld after 1 week. But to get the most from the Rotoweld, you must also consider the supply chain. If you can’t feed the machine with enough pipes, it won’t give you the best results.

Rotoweld technology adapts the welding process to varying conditions, such as changes in gap, alignment and root face. Pipe fitting must be done using root tacks, which need to be feathered with a grinder to let the automated welding adapt to it properly. The Rotoweld can handle gaps up to 6 mm and HI-LOs up to 75% of the gap. Practically, the system’s fast response time allows for high deposition rates and travel speeds at which weld pool conditions are so critical that they could not be sustained by hand.

Nothing out of the ordinary in the welding industry, but here are some benchmarks for heavy users:

Daily: fill torch contact tip
Weekly: fill torch liner
Monthly: root torch contact tip, camera window
3 months: Root torch contact tip and camera’s plastic disposable window
Yearly: Fill torch liner and water chiller coolant

The Rotoweld 3.0 comes with basic welding programs to accelerate the qualification of WPS.

Because of its optimised linear design, the Rotoweld 3.0 can be installed along the walls of a shop, or along the borders  between two production bays of a plant, which is usually square feet that are not optimised or used for piling stuff. What is important is to clear the centre of a shop where there is traffic and production flow.

Shops that follow these guidelines usually double their available floor space in the middle of the shop or bay, making more space for pipe fitting stations (required to feed 150+ inch dia per shift with a Rotoweld 3.0 Single Bay). This results in better spool line-up on the floor and easing the displacement of mobile fume extractors.

Some will compare an optimised linear station, like the Rotoweld 3.0, to a collaborative robot approach. Collaborative robots can give the impression that minor adjustments must be made to a shop to integrate them into production and claim that the required floor space is limited to the bolt pattern of the steel plate of the robot’s base (4’x4′). This is not the case when you consider the operational footprint required by the welding arm.

The Rotoweld, with its linear design, can be installed along the walls of a shop or along the borders between two production bays of a plant. The collaborative robot base cannot be mounted along a wall to save space. It has to be bolted towards the centre of the shop and needs approximately 10 feet perpendicularly to the pipe axis to perform all the maneuvers of welding a 30-foot spool.

So all in all, the footprint impact of a Rotoweld is slightly less than a collaborative robot for equivalent spool specifications. Finally, it is  important to keep in mind that an optimized Rotoweld 3.0 integration will usually liberate the space required  for increasing productivity.
