Collaborative welding robot designed for process pipe welding

SWR inproduction

Spool Welding Robot

The Spool Welding Robot (SWR) is a welding cobot designed specifically for pipe, small pressure vessel, and other types of roll welding. It is capable of welding flanges, Tees, elbows, reducers, and more.

By being a cobot, the SWR can be operated by junior welders and therefore, is able to improve shop productivity and produce consistent high-quality welds every time.

The SWR is a fast and efficient welding solution capable of storing and quickly recounting weld data and videos for accurate shop analysis and quality control. 

pipe spool welding automation
Pneumatic Manipulator with Adjustable Height: Easily move the arm between joints within 15 ft of base // Approach a full range of pipes from 2” to 60” at different heights
Slender design & compact head: Only 1.6” clearance around the pipe is required
Easy-To-Use Human-Machine Interface (HMI) allows operator to: Select the pre-programmed welding procedure // Tune the weld and motion parameters // Get access to the pass tracking feature and see the graphical representation of weld joint build-up during the weld
A light and durable pendant. Operators easily start, stop and change motion and weld parameters. Includes: 6.5″ resistive touch screen // Hardwired safety rated E-stop // Easy-to-find rocker switches, push buttons and joystick
Power Source: Different power source options available (Lincoln Power Wave® R450, Miller Auto-Continuum™ 500, Fronius TPS 400i LSC Advanced)
Laser Camera: Tracks the seam in real time – no prescan // Point Laser: Maintains the contact to work distance
Novarc’s welding vision system
Three-axis robotic arm: Imitates all roll welding motions // Moves torch up/down, left/right while creating weave motion
EWR 2: Saves shielding gas while providing better gas coverage

Conformité -Européenne

  • Does not block forklift traffic or interfere with shop flow


  • Semi-automated seam tracking using a laser scanner with 0.3 mm accuracy (for carbon and stainless steel pipes up to 0.75” in thickness and more than 4” in diameter)
  • Automatic stick-out distance control (tip to pipe distance) with 0.1 mm accuracy
productivity options

Open Platform

  • Ability to integrate with more than 2 positioners
  • Flexibility to integrate with existing positioners
  • Choice of power source: Lincoln Power Wave® R450, Miller Auto-Continuum™ 500, Fronius TPS 400i LSC Advanced

Welding Vision System

Novarc SWR’s groundbreaking weld monitoring system,
has a camera built into the robotic arm which records each weld.

  • Novarc’s welding vision system records every weld, with the key weld parameters on the video
  • Operators get a clear view from inside the groove on the HMI as each weld progresses in real time.
  • Supervisors get videos of all welds to analyze in parallel with the weld parameters saved by NovData™ to improve weld quality.
  • Operators can clearly see the effects and changes of the Tack Fusion™ and Root Save™ features.



Novarc’s comprehensive production monitoring software, NovData™, brings traceability and accountability into your production. It automatically creates the in-depth reports you need for accurate troubleshooting and enhanced Quality Control practices. The reports include:

  • Daily Operations Report (Operator name, number and sizes of pipes welded, job number, Welding Procedure Data Sheet; etc.)
  • Log Report (50 ms stamped values for voltage, current, WFS, travel speed, true energy and many other parameters; Operators name; Spool number; Work order; etc.)

Collaborative welding robot designed for high-mix low-volume production

Lower cost per weld

Consistent and repeatable root pass

SWR options

Multiple Power Sources

  • Lincoln Power Wave® R450
  • Miller Auto-Continuum™ 500

Works with Multiple Positioners

  • The SWR can easily be integrated to work with multiple positioners including Team Industries, Profax, Preston Eastin)
  • Novarc can integrate with one or more positioners based on your needs (up to five)
