Sure, cobots are lightweight: the largest UR10 robot is under 29 kg/64 lbs, so they’re easy to pick up and move from one process to another. But they’re no lightweights when it comes to heavy-duty processes like welding. In fact, there’s already a range of cobot welding systems to choose from. Surprised? Don’t be. It’s just one more smart application for these flexible, cost-effective, and easy-to-program automation tools.
The flexibility and ease-of-programming of cobot-based welding systems make them especially well-suited for low-volume/high-mix environments, as well as custom or small-template welding processes. But with high accuracy and repeatability, these systems can also handle long runs with consistent quality. Welding tasks can be programmed in as little as half-an-hour by workers who have no previous experience, and programs can be saved and reused, saving the expense of trained robot programmers. Lightweight cobot welders can be mounted on tabletops, hung from ceilings, or installed into existing welding booths, offering more flexibility than manual welders or traditional fixed robots. And speaking of manual welders, these will be increasingly harder to find. In the U.S. alone, the American Welding Society predicts a shortfall of 372,000 welders by 2026. Several companies have already announced cobot welding systems.
Numerous types of welding are possible with the UR robot, such as TIG, MIG, Spot, Arc, Ultrasound and Plasma. Reduced production downtime and less wasted material belong to the many advantages of deploying a collaborative robot arm.

The SnapWeld Collaborative Robot Welding package is a cobot-assisted, interactive welding system that can be deployed in existing, manual welding booths, so it eliminates the need for costly new robotic cells. The system is ideal for small job shops that are struggling with the budget, programming, and space requirements of traditional welding robots
The SnapWeld system includes a Profax wire feeder and water-cooled torch for welds up to 600 amps, along with the UR robot. One of the big advantages of using cobots for a welding application is the ease of programming. SnapWeld was developed with and verified by Universal Robots through the UR+ platform facilitating direct software integration into the UR programming environment, enabling advanced settings to be easily programmed directly on the robot’s teach pendant.
