We developed the SWR by working closely with manufacturing shops struggling to automate the pipe spool welding process. Pipe shops were frustrated by the lack of industry innovation and believed that conventional six-axis robots weren’t feasible for pipe welding, and that robots on rails were too limiting and too expensive.

Then we got to work.

Over the next 10 years, we mastered the design and creation of a robot whose precision and dexterity matches the exact needs of pipe shops to get the job (and welds!) done.

Reliable, Repeatable Weld Quality

  • Increased overall weld cleanliness using mechanized motion
  • Constant stick out using fully automatic laser-based height control
  • Ability to optimize sidewall fusion
  • Reduction in weld stops and starts and associated potential defects
  • Ability to monitor heat input on the HMI per pass or per joint
  • Steady, adjustable weave allowing you to optimize weave width for best mechanical properties
  • Consistent and repeatable tie-ins, root pass and penetration
  • Modified short circuit GMAW (STT, LSC, RMD) for root and GMAW, MCAW or FCAW for fill and cap passes using single torch or double torch configuration


Bottom Line

  • 4x increase in production capacity compared to root to cap manual SMAW
  • 30% faster travel speeds compared to manual MIG
  • 50% increase in production capacity compared to root to cap manual MIG
  • 75% lower cost per joint
  • 90% arc-on time

Quality and Data

  • Control how welds are done using pre-programmed automated welds
  • Increase quality of welds (learn more)
  • Supervisors will fully aware of stop starts and the reasons why
  • Access all weld and motion data using the SWR’s production monitoring software
  • Continue to improve robot performance by collecting and preserving welding data

Fast Deployment

  • Training in 2 days
  • Simple 2 day installation
  • Operational in as few as 4 days

Top Line

  • Tackle bigger projects while bidding with a lower cost base. Now that’s called a competitive advantage

Welding Capacity on Demand

  • Reduce dependency on finding scarce, highly-skilled pipe welders
  • Scale up quickly by easily training intermediate welders to weld pipes
  • Capture and retain welding skills within the SWR


  • Keep the production floor clear and open. The SWR will only take a 4’ by 6’ footprint
  • SWR does not interfere with overhead cranes or forklift traffic
  • No safety cell or fencing required with all the safety systems built into the robot
  • Multiple positioners can be used simultaneously

“Designed to semi-automate the pipe welding process by working with collaboratively with an operator, Novarc’s SWR increases the capacity of pipe shops, lowers the cost per joint and increases the weld quality. We are extremely impressed with the SWR’s ability to weld pipe modules up to 30 feet while taking only an 8 x 4 foot area. In fact, Novarc’s SWR has the potential to have a significant impact on the pipe fabrication process industry due to the shortage of trained pipe welders in a growing market of more than 10,000 pipe welding shops globally.”
