Connect your craft to the machine

SmoothTool is an easy-to-use cobot welding package that helps your welding robot deliver the perfect result – by learning from you.

We get a better working environment and less stress as the welder does not have to sit for long hours near the welding fumes and the heat, and at the same time profitability increases.

All you need to get the job done

SmoothTool is a robotic welding solution that helps you deliver your best work by putting you in charge of the automated welding process.

Offset welding

  • Copy and offset items in X, Y, Z direction or hand-guide the robot to your preferred offset position​ to ensure the best weld every time​

Stitch welding

  • Control your stitch weld with parameters, e.g., retraction, weld length, air speed, number of welds​

3D Viewer

  • Check if your welding path needs correcting before pressing start​
  • Zoom into different segments of the welding path for a closer look

Linear and circular weaving

  • Works on CB and e-series​
  • Set and adjust the amplitude, frequency and dwell time for the best result
  • Can also be combined with stitch welding

UR+ certified

  • SmoothTool is a ‘plug-and-play’ robotic welding kit that is tested and approved by Universal Robots
  • Compatible with UR3e, UR5e, UR10e, UR16e and CB-series collaborative robots (or cobots)

Power source independent

  • Use your preferred power source
  • Manage parameters using the UR teach pendant​ or directly on the power source

Programming Flange

  • Use the Programming Flange to show your robot how you want the job done
  • Doing it freehand makes this process a lot easier and faster

View your paths in 3D

SmoothTool’s 3D Viewer creates a virtual welding path so you can adjust the parameters to get the perfect weld first time and minimize the need for dry runs.


Make a basic welding program in just 4 steps

Step one

Approach: Set the point above the item you’re about to weld

step two

Weld Start: Set the starting point of your welding path (arc on)

step three

Weld End: Set the ending point of your welding path (arc off)

step four

Exit: Set the point above the item where the welding will end

Robotic welding is changing

Automated robotic welding used to be exclusive to large manufacturers that required high volumes of identical welds in their production workflow. Today, due to the development of collaborative robotics, robotic welding offers significant advantages to production companies large and small.

More accessible to SMEs

Small- and medium-sized production companies now have the opportunity to incorporate robotic welding into their workflows without risk.

  • Advancements in robotic welding allow production workers who have no previous robotics programming experience to learn how to operate a cobot within minutes.
  • With robotic welding having been around for some time, the start-up costs in adding a robot to the operation have decreased.
  • Cobots work alongside humans and therefore don’t need to be kept in a cage that takes up a lot of factory floor space. With cobots (such as those from Universal Robots) weighing as little as 11 kg, many production companies choose to mount their robot arm on a magnetized surface or a wheeled trolley so they can deploy it anywhere in the factory.

More profitable

By incorporating the robotic welding process into their workflows, SMEs benefit from reduced manufacturing costs and a shorter payback period on the robot through:

  • Increased efficiency and quality through consistency and repeatability of welds, resulting in improved ROI on smaller batches; and
  • Increased focus on design – giving the welder time to focus on more complex and profitable projects.

More attractive workplace

SMEs that use robotic welding in their operation can make up the shortfall in skilled welders through the efficiencies gained by adding a cobot to the team. 

In addition, SMEs can attract employees with a broader skill set who are ready to add robotic welding to their portfolio where the job will demand more of their expertise in decision making, attention to detail and customer service.

Studies show that robotic welding reduces instances of repetitive strain injury (RSI) in welders. As well as being good for employee wellbeing, it’s good for SMEs too as it reduces the risk of exposure to staff shortages.
