Collaborative welding robot designed for process pipe welding

SWR inproduction

Spool Welding Robot

The Spool Welding Robot (SWR) is a collaborative welding machine 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 collaborative robot, 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 (using Novarc’s AI-powered welding vision system, NovEye) 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 2” 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: Multiple power source options available
Laser Camera: Tracks the seam in real time – no prescan // Tracks the joint in XYZ axis (height, width, depth all adjusted automatically)
NovEye™: Novarc’s weld monitoring system
Three-axis robotic arm: Imitates all 1G welding motions // Moves torch up/down, left/right while creating weave motion

Conformité -Européenne

Complies with applicable European Community Directives  including European Directives for Safety of machinery (EN60204-1), electromagnetic compatibility (EN61000-6) and safety of collaborative robots (ISO 15066-2016).

productivity options


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

  • 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 proprietary comprehensive production monitoring software, NovData™, gives you the insights you need to scale your operation profitably. It automatically creates all the reports you need:

  • 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.)

Open Platform

  • Ability to integrate with more than 2 positioners
  • Easy integration with existing positioners
  • Choice of power source
