Vattholma Mekano AB logo

“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.”

Cobot welding quote

Alusteel logo

“Based on our needs and the purely financial, it makes much more sense to us. We ensure uniform products, and our welders avoid the tedious and repetitive work. They are happy with their new colleague.”

“The Smooth Robotics Software has hands down been epic in quick programming. I have found that if we have to weld more than 12” in length, it’s more effective to use the robot. Even for just 1 part. This is a game changer.”

Pre-integrated welding power sources

We’ve preconfigured SmoothTool to be compatible with several welding power sources that are ‘plug and play’. And we’ll keep adding more.

Digital I/O

RetroFit Kit

Integrate with any power source not pre-integrated in SmoothTool using the RetroFit Kit developed by Smooth Robotics.

Callback function

Digital I/O

You can set up SmoothTool by simply using Digital I/O with your power source.

Make a basic welding program in just 4 steps

Step 1

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

Step 2

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

Step 3

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

Step 4

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

The RetroFit Kit

Easily integrate your existing power source with SmoothTool using the RetroFit Kit by Smooth Robotics

If you have a welding power source that uses the EURO Connector, Miller connector, or Lincoln connector you can turn it into a powerful robotic welding unit by adding a cobot, SmoothTool, and the Retrofit Kit.

The kit consists of 3 parts:

  1. Connector plate
  2. Adaptor
  3. Feedback Shunt

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 of 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.
